使用rest api将文件上传到onedrive时显示进度条
问题描述：
我正在使用onedrive rest api将文件上传到onedrive。它使用client.asyncupload方法将文件上传到onedrive。它工作正常，但无法显示要上传的文件的百分比或进度。有人可以有任何参考吗？
以下是我上传文件到onedrive的代码。

string url = string.Format(@"https://apis.live.net/v5.0/me/skydrive/my_documents/files/{0}?access_token={1}",
Path.GetFileName(fileName), access_token);
using (var client = new WebClient())
{
client.UploadDataAsync(new Uri(url), "PUT", ImageToByteArray(fileName));
}

你好
使用Web客户端UploadProgressChanged事件
Hello
Use the web client UploadProgressChanged event
private void cmdBrowseAndUpload_Click(object sender, EventArgs e)
{
string fileName = string.Empty;
using (var dlg = new OpenFileDialog())
{
dlg.Filter = "All Files|*.*";
if (dlg.ShowDialog(this) == DialogResult.OK)
{
fileName = dlg.FileName;
}
}
string url = string.Format(@"https://apis.live.net/v5.0/me/skydrive/my_documents/files/{0}?access_token={1}",
Path.GetFileName(fileName), access_token);
using (var client = new WebClient())
{
client.UploadProgressChanged += new UploadProgressChangedEventHandler(client_UploadProgressChanged);
client.UploadDataAsync(new Uri(url), "PUT", ImageToByteArray(fileName));
}
}
void client_UploadProgressChanged(object sender, UploadProgressChangedEventArgs e)
{
//To do you code here.
//Progress changed code here
}
