你看了（HTTP的['爲文檔DownloadFileAsync']：// MSDN。 microsoft.com/en-us/library/ms144196.aspx）？ –

特別是，您認爲「異步」部分意味着什麼？ –

我將使用兩種方法，例如** DownloadFileAsync **和** DownloadFile **，但結果相同。 :( – Elshan

class Program 
{ 
    private static WebClient wc = new WebClient(); 
    private static ManualResetEvent handle = new ManualResetEvent(true); 
    private static void Main(string[] args) 
    { 

     wc.DownloadProgressChanged += WcOnDownloadProgressChanged; 
     wc.DownloadFileCompleted += WcOnDownloadFileCompleted; 
     wc.DownloadFileAsync(new Uri(@"http://www.nattyware.com/bin/pixie.exe"), @"C:\\pixie.exe"); 
     handle.WaitOne(); // wait for the async event to complete 

    } 

    private static void WcOnDownloadFileCompleted(object sender, AsyncCompletedEventArgs e) 
    { 
     if (!e.Cancelled && e.Error == null) 
     { 
      //async download completed successfully 
     } 
     handle.Set(); // in both the case let the void main() know that async event had finished so that i can quit 
    } 

    private static void WcOnDownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e) 
    { 
     // handle the progres in case of async 
     //e.ProgressPercentage 
    }
