I’m working on a desktop application that handles file uploads to Google Drive. Currently I have a synchronous upload function that works fine, but I want to add a progress bar so users can see upload status.
public static File SendFileToCloud(string filePath, string fileDescription, string contentType, int retryCount)
{
try
{
string fileName = Path.GetFileName(filePath);
var driveFile = new File {Title = fileName, Description = fileDescription, MimeType = contentType};
byte[] fileData = System.IO.File.ReadAllBytes(filePath);
var fileStream = new MemoryStream(fileData);
FilesResource.InsertMediaUpload uploadRequest = service.Files.Insert(driveFile, fileStream, "text/html");
uploadRequest.Convert = false;
uploadRequest.Upload();
File uploadedFile = uploadRequest.ResponseBody;
return uploadedFile;
}
catch (Exception ex)
{
if(retryCount < 10)
{
return SendFileToCloud(filePath, fileDescription, contentType, retryCount + 1);
}
else
{
throw ex;
}
}
}
My previous setup used FTP with async operations which made progress tracking easy. Is there a way to make the Google Drive InsertMediaUpload work asynchronously so I can update a progress bar during the upload process?
Switch from Upload() to UploadAsync() and add progress tracking. You’re loading the entire file into memory right now, which breaks with large files. Use FileStream directly instead of reading everything into a MemoryStream. For progress tracking, subscribe to the ProgressReporter event before calling UploadAsync(). It’ll give you bytes sent and total bytes. Set a reasonable ChunkSize on your upload request - this controls how often you get progress updates. I’ve found monitoring Google.Apis.Upload.UploadStatus helps handle completion and errors properly. Also throw in a CancellationToken so users can cancel long uploads.
yeah, deff doable! change Upload() to UploadAsync() and hook into the ProgressReporter event. something like: uploadRequest.ProgressReporter = new Progress(progress => { /* update ur progressbar here */ }); dont forget to make ur method async and use await. works great for large files.
To implement async file upload with progress tracking using the Google Drive API, utilize the IUploadProgress interface. Begin by switching to async methods, specifically by using await uploadRequest.UploadAsync() instead of the synchronous upload method. Establish a progress reporter for real-time feedback during the upload. It’s important to manage chunk sizes with uploadRequest.ChunkSize; smaller chunks provide more frequent updates at the potential cost of performance. In my experience, 1MB chunks were optimal with varied file sizes. Don’t forget to wrap your file stream in a using statement to prevent memory leaks and consider implementing a cancellation token for user flexibility on long uploads.
