I can't find a way to read the "initial key" property from an mp3 file to use the song information in my application.
I've already tried to find libraries which do the job for me. I found TagLib# which is a very cool solution for getting tags/properties of different file formats. (including mp3).
I can use this library to get the title, the artist, the beats per minute and so on.. only the initial key value is missing for my use which isn't featured, unfortunately.
I also tried to find other solutions which support the initial key property but I haven't found one.
I already found a source which seems to address the same issue and solves it with using TagLib#, but I can't figure out how he solved that problem.
Use Ctrl + F and search for "Initial" to find the code block.
You can find the link here
I'll post a short part of my code which can be used to determine different info about one song in a pattern like this: (["bpm"]"title" - "artist")
var file = TagLib.File.Create(filePath);
return $"[{file.Tag.BeatsPerMinute}]{file.Tag.Title} - {file.Tag.FirstPerformer}";
Thanks for any help or recommendations in advance! :)
Try this:
public static void Main(string[] args)
{
var path = …
var file = TagLib.File.Create (path);
var id3tag = (TagLib.Id3v2.Tag)file.GetTag (TagTypes.Id3v2);
var key = ReadInitialKey (id3tag);
Console.WriteLine ("Key = " + key);
}
static string ReadInitialKey(TagLib.Id3v2.Tag id3tag)
{
var frame = id3tag.GetFrames<TextInformationFrame>().Where (f => f.FrameId == "TKEY").FirstOrDefault();
return frame.Text.FirstOrDefault() ;
}
On Windows 10 you can also use:
async Task<string> ReadInitialKey(string path)
{
StorageFile file = await StorageFile.GetFileFromPathAsync(path);
Windows.Storage.FileProperties.MusicProperties musicProperties = await file.Properties.GetMusicPropertiesAsync();
var props = await musicProperties.RetrievePropertiesAsync(null);
var inkp = props["System.Music.InitialKey"];
return (string)inkp;
}
See here for documentation on MusicProperties object and here for the valid music properties.
You can use the Shell to read all MP3 properties.
Test on Windows 10, VS 2015 =>
// Add Reference Shell32.DLL
string sFolder = "e:\\";
string sFile= "01. IMANY - Don't Be so Shy (Filatov & Karas Remix).mp3";
List<string> arrProperties = new List<string>();
Shell objShell = new Shell();
Folder objFolder;
objFolder = objShell.NameSpace(sFolder);
int nMaxProperties = 332;
for (int i = 0; i < nMaxProperties; i++)
{
string sHeader = objFolder.GetDetailsOf(null, i);
arrProperties.Add(sHeader);
}
FolderItem objFolderItem = objFolder.ParseName(sFile);
if (objFolderItem != null)
{
for (int i = 0; i < arrProperties.Count; i++)
{
Console.WriteLine((i + ('\t' + (arrProperties[i] + (": " + objFolder.GetDetailsOf(objFolderItem, i))))));
}
}
Just borrowing code from nuget: mono TaglibSharp:
var tfile = TagLib.File.Create(#"..");
string initialKey = null;
if (tfile.GetTag(TagTypes.Id3v2) is TagLib.Id3v2.Tag id3v2)
{
/*
// test: add custom Initial Key tag
var frame = TextInformationFrame.Get(id3v2, "TKEY", true);
frame.Text = new[] {"qMMM"};
frame.TextEncoding = StringType.UTF8;
tfile.Save();
*/
var frame = TextInformationFrame.Get(id3v2, "TKEY", false);
initialKey = frame?.ToString();
}
I have an existing web site that allows the user (normally me) to upload pictures and then to display the image on the appropriate page. I am now trying to add this functionality to a new web site.
In visual studio I opened the new web site and did an ‘add existing item’ to copy the model/view/controller from the old web site. Made a few changes to remove unneeded functionality from the code and a few other minor things.
In both I store the image in a folder named /data/Images. When I execute the code for the new site (Lat34North) and add an image, the image gets added, and the everything appears to work (no errors).
Problem:
If I look at the folder (new solution) using “File Explorer”, the jpg appears, in this case, on my hard drive and in the correct folder.
If I try and access the folder (~/Data/Images) via Visual Studio, the jpg does not show up.
When I try and display the image from the web site, I just get that funny little icon you get when the image is not found.

The other difference between the two are the packages I have installed. Could I be missing one?
I'm using CefSharp in my WinForm project.
I wan't to clear the cache directory in real time:
if (browser != null)
{
BrowserPanel.Controls.Remove(browser);
browser = null;
}
String cachePath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + #"\TelegramParser\Users\" + userName;
if (Directory.Exists(cachePath))
{
Directory.Delete(cachePath, true);
}
But I always get an error that it is not possible to delete this directory.
This is how I declare the browser:
String cachePath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + #"\TelegramParser\Users\" + userName;
if (!System.IO.Directory.Exists(cachePath))
{
System.IO.Directory.CreateDirectory(cachePath);
}
var requestContextSettings = new RequestContextSettings { CachePath = cachePath };
if (browser != null && BrowserPanel.Controls.Contains(browser))
BrowserPanel.Controls.Remove(browser);
browser = new ChromiumWebBrowser();
browser.RequestContext = new RequestContext(requestContextSettings, new CustomRequestContextHandler());
browser.Dock = DockStyle.Fill;
JsDialogHandler js1 = new JsDialogHandler();
browser.JsDialogHandler = js1;
BrowserPanel.Controls.Add(browser);
browser.Load("https://google.com/");
What can I do to fix this?
As of 85.4 it is possible to delete cache of a running CefSharp browser using DevToolsClient and Network.ClearBrowserChache. As mentioned on General Usage wiki of CefSharp.
private async Task ClearCache(object sender)
{
using (var devToolsClient = Browser.GetDevToolsClient())
{
var response = await devToolsClient.Network.ClearBrowserCacheAsync();
}
}
Note: this will not deleted the entire folder, it will however clear cached objects.
I am trying to make a parser based on "AngleSharp".
I use the following code for download:
var itemsAttr = document.QuerySelectorAll("img[id='print_user_photo']");
string foto_url = itemsAttr[0].GetAttribute("src");
string path = pathFolderIMG + id_source + ".jpg";
WebClient webClient = new WebClient();
webClient.DownloadFile(foto_url, path);
For pages "type_1" -link - the code works.
For pages "type_2" - link - the code does not work.
How to download photos for pages "type_2"?
Please read the AngleSharp documentation carefully, e.g., looking at the FAQ we get:
var imageUrl = #"https://via.placeholder.com/150";
var localPath = #"g:\downloads\image.jpg";
var download = context.GetService<IDocumentLoader>().FetchAsync(new DocumentRequest(new Url(imageUrl)));
using (var response = await download.Task)
{
using (var target = File.OpenWrite(localPath))
{
await response.Content.CopyToAsync(target);
}
}
where we used a configuration like
var config = Configuration.Default.WithDefaultLoader(new LoaderOptions { IsResourceLoadingEnabled = true }).WithCookies();
var context = BrowsingContext.New(config);
Can someone please provide an example of how to use Google.Apis.Storage.v1 for uploading files to google cloud storage in c#?
I found that this basic operation is not as straight forward as you might expect. Google's documentation about it's Storage API is lacking in information about using it in C# (or any other .NET language). Searching for 'how to upload file to google cloud storage in c#' didn't exactly help me, so here is my working solution with some comments:
Preparation:
You need to create OAuth2 account in your Google Developers Console - go to Project/APIs & auth/Credentials.
Copy Client ID & Client Secret to your code. You will also need your Project name.
Code (it assumes that you've added Google.Apis.Storage.v1 via NuGet):
First, you need to authorize your requests:
var clientSecrets = new ClientSecrets();
clientSecrets.ClientId = clientId;
clientSecrets.ClientSecret = clientSecret;
//there are different scopes, which you can find here https://cloud.google.com/storage/docs/authentication
var scopes = new[] {#"https://www.googleapis.com/auth/devstorage.full_control"};
var cts = new CancellationTokenSource();
var userCredential = await GoogleWebAuthorizationBroker.AuthorizeAsync(clientSecrets,scopes, "yourGoogle#email", cts.Token);
Sometimes you might also want to refresh authorization token via:
await userCredential.RefreshTokenAsync(cts.Token);
You also need to create Storage Service:
var service = new Google.Apis.Storage.v1.StorageService();
Now you can make requests to Google Storage API.
Let's start with creating a new bucket:
var newBucket = new Google.Apis.Storage.v1.Data.Bucket()
{
Name = "your-bucket-name-1"
};
var newBucketQuery = service.Buckets.Insert(newBucket, projectName);
newBucketQuery.OauthToken = userCredential.Result.Token.AccessToken;
//you probably want to wrap this into try..catch block
newBucketQuery.Execute();
And it's done. Now, you can send a request to get list of all of your buckets:
var bucketsQuery = service.Buckets.List(projectName);
bucketsQuery.OauthToken = userCredential.Result.Token.AccessToken;
var buckets = bucketsQuery.Execute();
Last part is uploading new file:
//enter bucket name to which you want to upload file
var bucketToUpload = buckets.Items.FirstOrDefault().Name;
var newObject = new Object()
{
Bucket = bucketToUpload,
Name = "some-file-"+new Random().Next(1,666)
};
FileStream fileStream = null;
try
{
var dir = Directory.GetCurrentDirectory();
var path = Path.Combine(dir, "test.png");
fileStream = new FileStream(path, FileMode.Open);
var uploadRequest = new Google.Apis.Storage.v1.ObjectsResource.InsertMediaUpload(service, newObject,
bucketToUpload,fileStream,"image/png");
uploadRequest.OauthToken = userCredential.Result.Token.AccessToken;
await uploadRequest.UploadAsync();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
if (fileStream != null)
{
fileStream.Dispose();
}
}
And bam! New file will be visible in you Google Developers Console inside of selected bucket.
You can use Google Cloud APIs without SDK in the following ways:
Required api-key.json file
Install package Google.Apis.Auth.OAuth2 in order to authorize the
HTTP web request
You can set the default configuration for your application in this
way
I did the same using .NET core web API and details are given below:
Url details:
"GoogleCloudStorageBaseUrl": "https://www.googleapis.com/upload/storage/v1/b/",
"GoogleSpeechBaseUrl": "https://speech.googleapis.com/v1/operations/",
"GoogleLongRunningRecognizeBaseUrl": "https://speech.googleapis.com/v1/speech:longrunningrecognize",
"GoogleCloudScope": "https://www.googleapis.com/auth/cloud-platform",
public void GetConfiguration()
{
// Set global configuration
bucketName = _configuration.GetValue<string>("BucketName");
googleCloudStorageBaseUrl = _configuration.GetValue<string>("GoogleCloudStorageBaseUrl");
googleSpeechBaseUrl = _configuration.GetValue<string>("GoogleSpeechBaseUrl");
googleLongRunningRecognizeBaseUrl = _configuration.GetValue<string>("GoogleLongRunningRecognizeBaseUrl");
// Set google cloud credentials
string googleApplicationCredentialsPath = _configuration.GetValue<string>("GoogleCloudCredentialPath");
using (Stream stream = new FileStream(googleApplicationCredentialsPath, FileMode.Open, FileAccess.Read))
googleCredential = GoogleCredential.FromStream(stream).CreateScoped(_configuration.GetValue<string>("GoogleCloudScope"));
}
Get Oauth token:
public string GetOAuthToken()
{
return googleCredential.UnderlyingCredential.GetAccessTokenForRequestAsync("https://accounts.google.com/o/oauth2/v2/auth", CancellationToken.None).Result;
}
To upload file to cloud bucket:
public async Task<string> UploadMediaToCloud(string filePath, string objectName = null)
{
string bearerToken = GetOAuthToken();
byte[] fileBytes = File.ReadAllBytes(filePath);
objectName = objectName ?? Path.GetFileName(filePath);
var baseUrl = new Uri(string.Format(googleCloudStorageBaseUrl + "" + bucketName + "/o?uploadType=media&name=" + objectName + ""));
using (WebClient client = new WebClient())
{
client.Headers.Add(HttpRequestHeader.Authorization, "Bearer " + bearerToken);
client.Headers.Add(HttpRequestHeader.ContentType, "application/octet-stream");
byte[] response = await Task.Run(() => client.UploadData(baseUrl, "POST", fileBytes));
string responseInString = Encoding.UTF8.GetString(response);
return responseInString;
}
}
In order to perform any action to the cloud API, just need to make a HttpClient get/post request as per the requirement.
Thanks
This is for Google.Cloud.Storage.V1 (not Google.Apis.Storage.v1), but appears to be a bit simpler to perform an upload now. I started with the Client libraries "Getting Started" instructions to create a service account and bucket, then experimented to find out how to upload an image.
The process I followed was:
Sign up for Google Cloud free trial
Create a new project in Google Cloud (remember the project name\ID for later)
Create a Project Owner service account - this will result in a json file being downloaded that contains the service account credentials. Remember where you put that file.
The getting started docs get you to add the path to the JSON credentials file into an environment variable called GOOGLE_APPLICATION_CREDENTIALS - I couldn't get this to work through the provided instructions. Turns out it is not required, as you can just read the JSON file into a string and pass it to the client constructor.
I created an empty WPF project as a starting point, and a single ViewModel to house the application logic.
Install the Google.Cloud.Storage.V1 nuget package and it should pull in all the dependencies it needs.
Onto the code.

Use of Google.Apis.Storage.v1 for uploading files using SDK to google cloud storage in c#:
Required api-key.json file
Install the package Google.Cloud.Storage.V1; and Google.Apis.Auth.OAuth2;
The code is given below to upload the file to the cloud
private string UploadFile(string localPath, string objectName = null)
{
string projectId = ((Google.Apis.Auth.OAuth2.ServiceAccountCredential)googleCredential.UnderlyingCredential).ProjectId;
try
{
// Creates the new bucket.
var objResult = storageClient.CreateBucket(projectId, bucketName);
if (!string.IsNullOrEmpty(objResult.Id))
{
// Upload file to google cloud server
using (var f = File.OpenRead(localPath))
{
objectName = objectName ?? Path.GetFileName(localPath);
var objFileUploadStatus1 = storageClient.UploadObject(bucketName, objectName, null, f);
}
}
}
catch (Google.GoogleApiException ex)
{
// Error code =409, means bucket already created/exist then upload file in the bucket
if (ex.Error.Code == 409)
{
// Upload file to google cloud server
using (var f = File.OpenRead(localPath))
{
objectName = objectName ?? Path.GetFileName(localPath);
var objFileUploadStatus2 = storageClient.UploadObject(bucketName, objectName, null, f);
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
return objectName;
}
To set the credentials
private bool SetStorageCredentials()
{
bool status = true;
try
{
if (File.Exists(credential_path))
{
Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", credential_path);
using (Stream objStream = new FileStream(Environment.GetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS"), FileMode.Open, FileAccess.Read))
googleCredential = GoogleCredential.FromStream(objStream);
// Instantiates a client.
storageClient = StorageClient.Create();
channel = new Grpc.Core.Channel(SpeechClient.DefaultEndpoint.Host, googleCredential.ToChannelCredentials());
}
else
{
DialogResult result = MessageBox.Show("File " + Path.GetFileName(credential_path) + " does not exist. Please provide the correct path.");

I used SDK in one of my window application. You can use the same code according to your needs/requirements.
You'll be happy to know it still works in 2016...

Here are 2 examples that helped me to upload files to a bucket in Google Cloud Storage with Google.Cloud.Storage.V1 (not Google.Apis.Storage.v1):
Upload files to Google cloud storage using c#
Uploading .csv Files to Google Cloud Storage using C# .Net
I got both working on a C# Console Application just for testing purposes.
#February 2021
string _projectId = "YOUR-PROJECT-ID-GCP"; //ProjectID also present in the json file
GoogleCredential _credential = GoogleCredential.FromFile("credential-cloud-file-123418c9e06c.json");
/// <summary>
/// UploadFile to GCS Bucket
/// </summary>
/// <param name="bucketName"></param>
/// <param name="localPath">my-local-path/my-file-name</param>
/// <param name="objectName">my-file-name</param>
public void UploadFile(string bucketName, string localPath, string objectName)
{
var storage = StorageClient.Create(_credential);
using var fileStream = File.OpenRead(localPath);
storage.UploadObject(bucketName, objectName, null, fileStream);
Console.WriteLine($"Uploaded {objectName}.");
}
You get the credentials JSON file from the google cloud portal where you create a bucket under your project..
Simple, with auth:
private void SaveFileToGoogleStorage(string path, string? fileName, string ext)
{
var filePath = Path.Combine(path, fileName + ext);
var gcCredentialsPath = Path.Combine(Environment.CurrentDirectory, "gc_sa_key.json");
Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", gcCredentialsPath);
var gcsStorage = StorageClient.Create();
using var f = File.OpenRead(filePath);
var objectName = Path.GetFileName(filePath);
gcsStorage.UploadObject(_bucketName, objectName, null, f);
Console.WriteLine($"Uploaded {objectName}.");
}
