C# write textfile from google calendar api - c#

I need some help. Probably it is easy, but I don't get it.
In our firestation is a screen where the alerts are shown (address, keyword, ...). When there is no alert I'd like to show upcoming events like birthdays, etc. The software running the screen needs ".txt"-files for input.
So what I want to do is: I create a google calendar and put all the events in it. Every night the task scheduler runns a little piece of software and downloads the events from google, writes everything in one file and the alert-software reads this file.
Until now I got so far:
I created a google calendar api.
I downloaded a code sample from google and got it working with two calendars.
And that's it. Now I got stuck all day long and I guess I'm a better firefighter than programmer. So I need help. Please give me some hints how to do it.

I would suggest you to create a List<String> object (possibly named ListOfLines, initially empty, and then go on adding one string for each line you'd like your file to have. Then, when you already have all your lines in the list (in appropriate order), you just use File.WriteAllLines(filename, ListOfStrings), and a file will be created with the given filename, whose lines will be the strings in the list.
From what I have seen, you'd just replace Console.Writeline(somestring) by ListOfLines.Add(somestring) on your current code.
Also, mind that you don't need to explicitly add a newline to your strings, File.WriteLines does that for you.

Downloading file from MS teams programatically

Previously, I developed an application which downloaded a file from a corporate Sharepoint site and then performed some magic with it.
The powers that be have since migrated to MS Teams and I'm trying to update the application to use the new platform. However, I'm having all sorts of issues getting the file to download.
My old (working for Sharepoint) code uses a WebClient to retrieve the file based on credentials previously provided by the user:
private string GetSchedule(string username, string password, string domain)
{
string tempPath = Path.GetTempFileName().Replace(".tmp", ".xlsm");
using (WebClient client = new WebClient())
{
client.Credentials = new NetworkCredential(username, password, domain);
try
{
client.DownloadFile(_networkSchedulePath, tempPath);
}
catch (WebException e)
{
if (e.Message.Contains("401"))
{
StatusUpdated?.Invoke(this, new EventArgs<string>("Invalid Credentials Provided"));
Finished?.Invoke(this, null);
return null;
}
if (e.Message.Contains("404"))
{
StatusUpdated?.Invoke(this, new EventArgs<string>("File Not Found"));
Finished?.Invoke(this, null);
return null;
}
else
{
StatusUpdated?.Invoke(this, new EventArgs<string>(e.Message));
Finished?.Invoke(this, null);
return null;
}
}
}
return tempPath;
}
However, when I use this with the new teams link I'm getting a 403 Forbidden error. So is there any way to programmatically retrieve a file from MS Teams?
I was mistaken in the comments. Simply replacing the NetworkCredentials with SharePointOnlineCredentials is not the solution.
I'm not sure if the following is the "right" approach, but it works and seems pretty solid. Please give it a try:
private static string GetFile(string path, string username, string password, string domain)
{
var secureString = new SecureString();
foreach (var ch in password)
{
secureString.AppendChar(ch);
}
string tempPath = Path.GetTempFileName().Replace(".tmp", ".xlsm");
using (WebClient client = new WebClient())
{
var credentials = new SharePointOnlineCredentials(username, secureString);
client.Headers[HttpRequestHeader.Cookie] = credentials.GetAuthenticationCookie(new Uri(path));
try
{
client.DownloadFile(path, tempPath);
}
catch (WebException e)
{
// Error Handling
}
}
return tempPath;
}
Another option is to use the CSOM rather than using a webclient directly. n.b., I encountered errors at the OpenBinaryDirect() call when using the Microsoft.SharePoint.Client NuGet package and it looks like this package is wildly out of date. It appears that the one to use now is Microsoft.SharePointOnline.CSOM or Microsoft.SharePoint2019.CSOM:
private static string GetFileWithClientContext(string path, string username, string password, string domain)
{
var secureString = new SecureString();
foreach (var ch in password)
{
secureString.AppendChar(ch);
}
string tempPath = Path.GetTempFileName().Replace(".tmp", Path.GetExtension(path));
using (var context = new ClientContext(path))
{
context.Credentials = new SharePointOnlineCredentials(username, secureString);
try
{
using (var file = Microsoft.SharePoint.Client.File.OpenBinaryDirect(context, new Uri(path).AbsolutePath))
using (var outFile = System.IO.File.OpenWrite(tempPath))
{
file.Stream.CopyTo(outFile);
}
}
catch (WebException e)
{
// Error Handling
}
}
return tempPath;
}
Thanks to JLRishe for the help his answer and comments provided. However, the final solution varied from the one in his answer, which is why I'm posting it here:
The OfficeDevPnP.Core package is used extensively for this.
Firstly, the AuthenticationManager is used to get a ClientContext in terms of the specific sharepoint site that needs to be accessed. This pops a window up to allow for the MFA. Then various components are loaded in via the ClientContext object. From here, the file is fetched via Guid and dumped to disk.
private string GetSchedule()
{
string tempPath = Path.GetTempFileName().Replace(".tmp", ".xlsm");
try
{
AuthenticationManager authManager = new OfficeDevPnP.Core.AuthenticationManager();
ClientContext ctx = authManager.GetWebLoginClientContext("https://oursite.sharepoint.com/sites/ourspecificsite/");
Web web = ctx.Web;
Microsoft.SharePoint.Client.File schedule = web.GetFileById(new Guid("ourguid"));
ctx.Load(web);
ctx.Load(schedule);
ctx.ExecuteQuery();
FileInformation fInfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(ctx, schedule.ServerRelativeUrl);
using (var fileStream = File.Create(tempPath))
{
fInfo.Stream.CopyTo(fileStream);
}
}
catch (WebException e)
{
StatusUpdated?.Invoke(this, new EventArgs<string>(e.Message));
return null;
}
return tempPath;

Retrieving more than 100 message ids from Gmail API

I have 3000 emails in my gmail account. I want to create an aggregated list of all the senders so that I can more effectively clean up my inbox. I dont need to download the message bodys or the attachments.
I used this sample to get me started (https://developers.google.com/gmail/api/quickstart/dotnet) althought now I cant figure out how to return more than 100 message ids when i execute this code:

var messageList = new List<Message>();
ListMessagesResponse messageResponse1 = new ListMessagesResponse();
var k = 0;
do
{
messageResponse1 = messageRequest.Execute();
messageList.AddRange(messageResponse1.Messages);
var output = $"Request {k} - Message Count: {messageList.Count()} Page Token: {messageRequest.PageToken} - Next Page Token: {messageResponse1.NextPageToken}";
Console.WriteLine(output);

return source
.Select((x, i) => new { Index = i, Value = x })
.GroupBy(x => x.Index / chunkSize)
.Select(x => x.Select(v => v.Value));
}
}
}
The research I've done says I need to use a batch request and based on the information I've found Im not able to adapt it to what I'm trying to accomplish. My understanding is that I would use the batch request to get all of the message ids and then 3000 individual calls to get the actual from, subject, and date received from each email in my inbox??
You can use paging to get a full list.
Pass the page token from the previous page to get the next call to Users.Messages.List (don't pass into the first call to get things started). Detect the end when the result contains no messages.
This allows you to get all the messages in the mailbox.
NB. I suggest you make the code async: if there are more than a few messages to read, it can take an appreciable time to get them all.
You can also use PageStreamer to get the remainder of the results.
var pageStreamer = new PageStreamer<Google.Apis.Gmail.v1.Data.Message, UsersResource.MessagesResource.ListRequest, ListMessagesResponse, string>(
(request, token) => request.PageToken = token,
response => response.NextPageToken,
response => response.Messages);
var req = service.Users.Messages.List("me");
req.MaxResults = 1000;
foreach (var result in pageStreamer.Fetch(req))
{
Console.WriteLine(result.Id);
}
This code will continue to run as long as there are additional results to request. Batching isnt really going to help you here as there is no way to know what the next page token will be.

specify an email address for Google Calendar notifications via api

How do I specify an email address for GoogleCalendar API notifications?
I need to programatically manipulate my Google Calendar via the Google API using C# dot-net. I've been able to create, delete and modify events successfully, but I'd like some control over notifications. Currently only email and UI popup options are available, and email defaults to the Google email account.
What I'm thinking is that if I can manipulate the email address used, I can send email to my Verizon email-to-SMS address, and send a text message instead of email (SMS is an option only for Government accounts). Or possibly to a dummy email that interfaces to an SMS service like Twilio. Bottom line is I would like to send email notifications to one or more email addresses of my choosing.
The only option for email is in a constructor for an EventReminder override:
new EventReminder{Method="email",Minutes=60};
Here's my working code:
namespace stuff
{
class Program
{
static string[] Scopes = { CalendarService.Scope.Calendar };
static string ApplicationName = "Google Calendar API .NET Quickstart";
static string _Chelle = "fake_id#gmail.com";
static string _EventCalendar = "jwejq36jjgwijg54iw7yjs7j7e#group.calendar.google.com";

{
UserCredential credential;
using (var stream =

credPath = Path.Combine(credPath, ".credentials/calendar-dotnet-quickstart.json");
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
Scopes,
"user",
CancellationToken.None,
new FileDataStore(credPath, true)).Result;
Console.WriteLine("Credential file saved to: " + credPath);
}
// Create Google Calendar API service.
var service = new CalendarService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = ApplicationName,
});
EventsResource.ListRequest request = service.Events.List(_EventCalendar);
request.TimeMin = DateTime.Now;
request.TimeMax = DateTime.Now.AddDays(30);
request.ShowDeleted = false;
Events events = request.Execute();
if (events.Items != null && events.Items.Count > 0)
{
foreach (var eventItem in events.Items)
{
// add new reminders
eventItem.Reminders = new Event.RemindersData
{
UseDefault = false,
Overrides = new[]
{
new EventReminder {Method="popup",Minutes=((60*24*7) - (60*9)) }, // one week before # 0900
new EventReminder {Method="email",Minutes=((60*24*7) - (60*9)) }
}
};
try
{
service.Events.Update(eventItem, _EventCalendar, eventItem.Id).Execute();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
Thread.Sleep(1000);

The redirect URI in the request: http://localhost:12349/authorize/ did not match a registered redirect URI

I'm getting this error while trying to run my c# console application... I am trying to call google calender api v3 to fetch calender and add event to calender.

This is my redirect URIs in my GoogleDevelopers Console project.
Redirect URIs: http://localhost:7744/authorize/
And this is the error message shown in browser.
I couldn't find any way to resolve this problem. Some help will be appreciable. I also search all the realted post in stackoverflow. But I couldn't find it's solution.
I think you are doing something wrong while "create client id" in GoogleDevelopers Console. Make sure that you have chosed "Installed application" in application type to access your project from console application.
Have a look in the attached image. According to request type you must create clientid
and credintials in your registered application in Google Developers Console.
You don't need to define redirect uri in console application while authenticating.
I was having this error on a simple test program (https://ctrlq.org/google.apps.script/docs/guides/rest/quickstart/dotnet.html), and it happens to be the client_secret.json was th wrong one, download it again and it worked.

Have you used Google's Directory API?

I'm trying to use Google Directory API Library for .NET to maintain email addresses for a domain. The latest library is google-admin-directory_v1-rev6-csharp-1.4.0-beta. The best and farthest I've gotten so far is to receive a 403 error (Not Authorized to access this resource/api).
Has anyone out there successfully used it? If so, could you share some code, tips, or tricks?
I have used it and got some success in creating a console-application.
At the moment I'm trying to find a way to skip the copy/paste of the authorization code.
Don't forget to turn on API access in your APIs Console.
