如何在 C# 中通过 FileStream 和 ResumableUploader 上传/更新文件

Question

我想通过 Google Documents List API(C#) 中的 System.IO.FileStream 上传/更新文件？

我使用以下两种方式：Google.GData.Client.ResumableUpload.ResumableUploader
(1) public void UpdateAsync(Authenticator authentication, AbstractEntry payload, object userData)
(2) public void UpdateAsync(Authenticator authentication, Uri resumableUploadUri, Stream payload, string contentType, object userData)

(1) 成功。
(2) 因 403 Forbidden 或其他原因失败...

那么，有人有关于（2）的示例代码吗？

我的 (2) 代码： 此代码由 Claudio Cherubino 的示例代码编辑，用于将文件流上传到 Google 文档（驱动器）。但是文件（DocumentEntry）的名称在 Google Drive 的页面上显示为“Untitled”。似乎“蛞蝓”不起作用。我错过了一些重要的设置吗？

Google.GData.Documents.DocumentsService conn =
new Google.GData.Documents.DocumentsService("TestSend");
conn.setUserCredentials("UserName", "UserPass");

string path = @"D:\test_file\test.exe"; 

Google.GData.Client.ResumableUpload.ResumableUploader send =
new Google.GData.Client.ResumableUpload.ResumableUploader();
send.AsyncOperationCompleted += new Google.GData.Client.AsyncOperationCompletedEventHandler(
    delegate(object sender,
        Google.GData.Client.AsyncOperationCompletedEventArgs e)
    {
        System.Windows.Forms.MessageBox.Show("File Send Done");
    }
);

System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite);

send.InsertAsync(
    new Google.GData.Client.ClientLoginAuthenticator("TestSend", "writely", this._DiskConn.Credentials),
    new System.Uri("https://docs.google.com/feeds/upload/create-session/default/private/full?v=3"),
    fs,
    "application/octet-stream",
    System.IO.Path.GetFileName(path),
    new object()
);

试试下面的代码：

DocumentsService service = new DocumentsService("MyDocumentsListIntegration-v1");
ClientLoginAuthenticator authenticator = new ClientLoginAuthenticator(APPLICATION_NAME, ServiceNames.Documents, USERNAME, PASSWORD);

string slug = "Legal contract";
MediaFileSource mediaSource = new MediaFileSource("c:\\contract.txt", "text/plain");
Uri createUploadUrl = new Uri("https://docs.google.com/feeds/upload/create-session/default/private/full?v=3");

ResumableUploader ru = new ResumableUploader();
ru.InsertAsync(authenticator, createUploadUrl, mediaSource.GetDataStream(), mediaSource.ContentType, slug, new object());
