远程服务器返回错误：（404）未找到

Question

我运行的我webpage.

这段代码获得源代码（如字符串）的问题是，为什么这个函数会返回404错误？

Private Function getPageSource(ByVal URL As String) As String 
    Dim webClient As New System.Net.WebClient() 
    Dim strSource As String = webClient.DownloadString(URL) 
    webClient.Dispose() 
    Return strSource 
End Function

试试这个

使用系统;使用System.IO的 ;使用System.Net的 ; using System.Text;

public static void GetFile 
     ( 
     string strURL, 
     string strFilePath 
     ) 
    { 

     WebRequest myWebRequest = WebRequest.Create(strURL); 

     WebResponse myWebResponse = myWebRequest.GetResponse(); 

     Stream ReceiveStream = myWebResponse.GetResponseStream(); 

     Encoding encode = System.Text.Encoding.GetEncoding("utf-8"); 

     StreamReader readStream = new StreamReader(ReceiveStream, encode); 

     string strResponse=readStream.ReadToEnd(); 

     StreamWriter oSw=new StreamWriter(strFilePath); 

     oSw.WriteLine(strResponse); 

     oSw.Close(); 

     readStream.Close(); 

     myWebResponse.Close(); 

    }
