c# - 如何在c#中快速上传文件到服务器

Question

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("request_uri_string");
FileStream fileStream = new FileStream("path_to_my_file", FileMode.Open, FileAccess.Read); 
Stream requestStream = request.GetRequestStream(); 
byte[] buffer = new Byte[checked((uint)Math.Min(4096, (int)fileStream.Length))];   
int bytesRead = 1;
while (bytesRead != 0)
{
    bytesRead = fileStream.Read(buffer, 0, buffer.Length);
    if (bytesRead > 0)
    {
        requestStream.Write(buffer, 0, bytesRead);
    }
} 
request.Close(); 
fileStream .Close(); 

目前我正在使用上面的代码。

还有比这更好(意味着快速)的其他方法吗？

不确定这是否更快，但可读性更高:

using (var webClient = new WebClient())
{
    webClient.DownloadFile(remoteFileUrl, localFileName);
}

编辑:

因为 WebClient 是 IDisposable，所以应该正确处理它(我添加了 using)。

MSDN 说:

This method uses the RETR command to download an FTP resource. For an HTTP resource, the GET method is used.
