After reading the migration infos from Google on the Gdrive.v3 SDK here: https://developers.google.com/drive/v3/web/migration, I#m still not really sure how I can set the ParentReference (to the root folder) for a file correctly. Currently in v2 this is done via:
private string UploadToGDrive( Google.Apis.Drive.v3.DriveService service, string uploadFile, string parent)
{
var body = new Google.Apis.Drive.v3.Data.File
{
Name = Path.GetFileName(uploadFile),
Description = uploadFile,
MimeType = GetMimeType(uploadFile),
Parents = new List<ParentReference> {new ParentReference {Id = parent}}
};
}
private string GetMimeType(string fileName)
{
var mimeType = "application/unknown";
var extension = Path.GetExtension(fileName);
if (extension == null) return mimeType;
var ext = extension.ToLower();
var regKey = Registry.ClassesRoot.OpenSubKey(ext);
if (regKey?.GetValue("Content Type") != null) return mimeType;
if (regKey != null) mimeType = regKey.GetValue("Content Type").ToString();
return mimeType;
}
As stated in the document - Inserting a file in a folder:
To insert a file in a particular folder, specify the correct ID in the parents property of the file, as shown:
var folderId = "0BwwA4oUTeiV1TGRPeTVjaWRDY1E";
var fileMetadata = new File()
{
Name = "photo.jpg",
Parents = new List<string>
{
folderId
}
};
FilesResource.CreateMediaUpload request;
using (var stream = new System.IO.FileStream("files/photo.jpg",
System.IO.FileMode.Open))
{
request = driveService.Files.Create(
fileMetadata, stream, "image/jpeg");
request.Fields = "id";
request.Upload();
}
var file = request.ResponseBody;
Console.WriteLine("File ID: " + file.Id);
Hope this helps.
I must have overseen this... It simply means in my case to replace
var body = new Google.Apis.Drive.v3.Data.File
{
Name = Path.GetFileName(uploadFile),
Description = uploadFile,
MimeType = GetMimeType(uploadFile),
Parents = new List<ParentReference> {new ParentReference {Id = parent}}
};
with
var body = new Google.Apis.Drive.v3.Data.File
{
Name = Path.GetFileName(uploadFile),
Description = uploadFile,
MimeType = GetMimeType(uploadFile),
Parents = new List<string> {parent}
};
(I've added this as an answer as it is to long for a comment).

I am trying to move data for example;
Source = "Uploads/Photos/" to Destination="Uploads/mytest/"
I am getting error like that but but when i give a specific file this works.
Basically, I want to move folder with all files.
My code is below;
public async Task<MoveResponse> MoveObject(MoveRequest moveRequest)
{
MoveResponse moveResponse = new MoveResponse();
CopyObjectRequest copyObjectRequest = new CopyObjectRequest
{
SourceBucket = moveRequest.BucketName,
DestinationBucket = moveRequest.BucketName + "/" + moveRequest.Destination,
SourceKey = moveRequest.Source,
DestinationKey = moveRequest.Source,
};
var response1 = await client.CopyObjectAsync(copyObjectRequest).ConfigureAwait(false);
if (response1.HttpStatusCode != System.Net.HttpStatusCode.OK)
{
moveResponse.IsError = true;
moveResponse.ErrorMessage = "Files could not moved to destination!";
return moveResponse;
}
return moveResponse;
}
I hope, you are using high level S3 API's.
Check out this sample code
private void uploadFolderToolStripMenuItem_Click(object sender, EventArgs e)
{
string directoryPath = textBoxBasePath.Text + listBoxFolder.SelectedItem.ToString().Replace("[", "").Replace("]", "");
string bucketName = comboBoxBucketNames.Text;
string FolderName = listBoxFolder.SelectedItem.ToString().Replace("[", "").Replace("]", "");
try
{
TransferUtility directoryTransferUtility = new TransferUtility(new AmazonS3Client(AwsAccessKeyID, AwsSecretAccessKey, RegionEndpoint.USEast1));
TransferUtilityUploadDirectoryRequest request = new TransferUtilityUploadDirectoryRequest
{
BucketName = bucketName,
KeyPrefix = FolderName,
StorageClass = S3StorageClass.StandardInfrequentAccess,
ServerSideEncryptionMethod = ServerSideEncryptionMethod.AES256,
Directory = directoryPath,
SearchOption = SearchOption.AllDirectories,
SearchPattern = "*.*",
CannedACL = S3CannedACL.AuthenticatedRead
};
ListMultipartUploadsRequest req1 = new ListMultipartUploadsRequest
{
BucketName = bucketName
};
var t = Task.Factory.FromAsync(directoryTransferUtility.BeginUploadDirectory, directoryTransferUtility.EndUploadDirectory, request, null);
t.Wait();
MessageBox.Show(string.Format("The Directory '{0}' is successfully uploaded", FolderName));
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);

I am just trying to learn ASP.NET MVC and am having an issue, well not so much of an issue but lack of understanding any is not working I am trying to update an SQL table, the code below works fine if I want to delete a table but all I want to do is to add another file to the data table
public async Task<IActionResult> DeleteSnTFileFromFileSystem(int id)
{
var file = await context.SnTModels.Where(x => x.Id == id).FirstOrDefaultAsync();
if (file == null)
return null;
var basePath = Path.Combine(Directory.GetCurrentDirectory() + "\\wwwroot" + file.FilePath);
if (System.IO.File.Exists(basePath))
{
System.IO.File.Delete(basePath);
}
context.SnTModels.Remove(file);
context.SaveChanges();
TempData["Message"] = $"Removed {file.Name + file.Extension} successfully from File System.";
return RedirectToAction("Scenario");
}
Here is my code to create the table
[HttpPost]
public async Task<IActionResult> SnTUploadToFileSystem(List<IFormFile> files, string description)
{
foreach (var file in files)
{
var subPath = "\\*dir file\\";
var basePath = Path.Combine(Directory.GetCurrentDirectory() + "\\wwwroot" + subPath);
bool basePathExists = System.IO.Directory.Exists(basePath);
if (!basePathExists)
Directory.CreateDirectory(basePath);
var fileName = Path.GetFileNameWithoutExtension(file.FileName);
var filePath = Path.Combine(basePath, file.FileName);
var extension = Path.GetExtension(file.FileName);
if (!System.IO.File.Exists(filePath))
{
// saving our file to the file system
using (var stream = new FileStream(filePath, FileMode.Create))
{
await file.CopyToAsync(stream);
}
// creating a model and save this model into the db
var SnTModel = new SnTOnFileSystem
{
CreatedOn = DateTime.UtcNow,
FileType = file.ContentType,
Extension = extension,
Name = fileName,
Description = description,
FilePath = subPath + file.FileName
};
context.SnTModels.Add(SnTModel);
context.SaveChanges();
}
}
TempData["Message"] = "File successfully uploaded to File System.";
return RedirectToAction("Index");
}
Here is the post to update the table

I upload image from angular to .net core but the file input I receive always null , with the postman , it's receive exactly. I don't know why ?
Can you help me how to solve it?
Thank you so much !

I've been trying to download .xml file, but sadly unsuccesfully.
From angular side I am sending *.xml file. In .NET side I take it to process and create a new *.xml file. And I need to download that new file, however I can't really find out how to workaround it.
this is my file-component.ts:
OnSubmit(value, File) {
const params1: FormData = new FormData();
params1.append('File', this.fileToUpload, this.fileToUpload.name);
params1.append('ProcessingMode', value.processingMode);
params1.append('StartDate', value.startDate.formatted);
const params = {
'File': this.fileToUpload,
'ProcessingMode': value.processingMode,
'StartDate': value.startDate.formatted
};
this.mapsConfigurationService.postFile(value, this.fileToUpload, value.startDate.formatted)
.subscribe((res: any) => {
this.downloadFile(res, 'xml'); debugger;
this.xmlProcessing = false;
},
(err) => {
if (err.status === 401) {
// this.router.navigate(['unauthorized']);
} else {
this.xmlProcessing = false;
}
});
downloadFile(data, type) {
const fileName = 'test';
var contentType;
if (type === 'xml') {
contentType = 'text/xml';
}
var blob = new Blob([data._body], { type: contentType });
const dwldLink = document.createElement('a');
const url = URL.createObjectURL(blob);
const isSafariBrowser = navigator.userAgent.indexOf('Safari') !== -1 && navigator.userAgent.indexOf('Chrome') === -1;
if (isSafariBrowser) {
dwldLink.setAttribute('target', '_blank');
}
const fullFileName = fileName + '.' + type;
dwldLink.setAttribute('href', url);
dwldLink.setAttribute('download', fullFileName);
dwldLink.style.visibility = 'hidden';
document.body.appendChild(dwldLink);
dwldLink.click();
document.body.removeChild(dwldLink);}
this is service.ts
postFile(value: any, fileToUpload: File, startDate) {
const formData: FormData = new FormData();
formData.append('File', fileToUpload, fileToUpload.name);
formData.append('ProcessingMode', value.processingMode);
formData.append('StartDate', '2015-05-23');
return this.http
.post(this.Url, formData);
}
and this is backend side:
[HttpPost, DisableRequestSizeLimit]
public ActionResult UploadFile()
{
try
{
var xml = Request.Form.Files["File"].ToString();
var httpRequest = HttpContext.Request.Form;
var postedFile = httpRequest.Files["File"];
string outputFile = Request.Form["info"].ToString();
var startDate = Request.Form["StartDate"];
var file = httpRequest.Files[0];
string fullPath = "";
string folderName = "Upload";
string antFile = #"C:\ant.bat";
string build = #"C:\build.xml";
string rootPath = #"C:\Users";
string newPath = Path.Combine(rootPath, folderName);
if (!Directory.Exists(newPath))
{
Directory.CreateDirectory(newPath);
}
if (file.Length > 0)
{
string fileName = ContentDispositionHeaderValue.Parse(file.ContentDisposition).FileName.Trim('"');
fullPath = Path.Combine(newPath, fileName);
using (var stream = new FileStream(fullPath, FileMode.Create))
{
file.CopyTo(stream);
}
}
return PhysicalFile(#"C:\Book1.xml", "application/xml", "Book1.xml");
}
catch (System.Exception ex)
{
return StatusCode(500);
}
}
I get error 500 and I do understand that the problem is with RequestHeaders but I can't figure out the way to solve it and in which side
for downloading for downloading any file... I am use this code in backend
and make and request the code from angular by normal http request
var myFile :: your file
if (System.IO.File.Exists (myFile.Path)) {// to know if the file is Exist or not
//Process File Here ...
} else {
return Json ("NotFound");
}
string contentType = "application/xml";
HttpContext.Response.ContentType = contentType;
var result = new FileContentResult (System.IO.File.ReadAllBytes (myFile.Path), contentType) {
FileDownloadName = $"{myFile.Title }" // + myFile.Extension
};
// System.IO.File.Delete (myFile.Path); //if you want to delete the file after download
return result;
Is there any possible way to get the list of files with parent folder name and without making additional queries?
My Files.List() code sample:
var sheets = new List<File>();
var sheetsRequest = Service.Files.List();
sheetsRequest.Fields = "nextPageToken, files(id, name, owners, parents)";
sheetsRequest.Q = $"mimeType = '{mimeType}' and name = '{name}'";
sheetsRequest.PageSize = 500;
var sheetsFeed = await sheetsRequest.ExecuteAsync();
while (sheetsFeed.Files != null)
{
foreach (var file in sheetsFeed.Files)
{
sheets.Add(file);
}
if (sheetsFeed.NextPageToken == null)
break;
sheetsRequest.PageToken = sheetsFeed.NextPageToken;
sheetsFeed = await sheetsRequest.ExecuteAsync();
}
return sheets;
Because for now I making GetFileParentDirAsync call for each File using following method (and it's very slow):
public async Task<string> GetFileParentDirAsync(File file)
{
return await Task.Run(async () =>
{
var folderName = string.Empty;
if (file.Parents?.First() == null) return folderName;
var parentId = file.Parents.First();
var parentRequest = Service.Files.Get(parentId);
var parentResponse = await parentRequest.ExecuteAsync();
folderName = parentResponse.Name;
return folderName;
});
}
Thanks.
