請求的URI是這個FTP命令

Question

我在Visual Studio 2010中

WebRequest request = WebRequest.Create("ftp://myftp.com"); 
      request.Method = WebRequestMethods.Ftp.MakeDirectory; 
      request.Credentials = new NetworkCredential("myusername", "12344"); 
      using (var resp = (FtpWebResponse)request.GetResponse()) 
      { 
       Console.WriteLine(resp.StatusCode); 
      } 

添加以下代碼在我的C＃.NET應用程序，但我收到以下錯誤無效。

The requested URI is invalid for this FTP command. 

請建議解決方案。謝謝

Answer 1

如果你只是要檢查文件信息，你應該嘗試改變request.Method到WebRequestMethods.Ftp.ListDirectoryDetails代替：

WebRequest request = WebRequest.Create("ftp://myftp.com"); 
     request.Method = WebRequestMethods.Ftp.ListDirectoryDetails; 
     request.Credentials = new NetworkCredential("myusername", "12344"); 
     using (var resp = (FtpWebResponse)request.GetResponse()) 
     { 
      Console.WriteLine(resp.StatusCode); 
     } 

Answer 2

你必須指定一個你想創建的子目錄;你不能創建根，這就是你想要做的。因此錯誤。

Answer 3

烏里應該是FTP：// + IP或ftpServerName +/Folder_to_create_Name

於是，看見的請按照下面的代碼：

WebRequest request = WebRequest.Create("ftp://myftp.com/FOLDER_TO_CREATE/"); 
request.Method = WebRequestMethods.Ftp.MakeDirectory; 
request.Credentials = new NetworkCredential("myusername", "12344"); 

using (var resp = (FtpWebResponse)request.GetResponse()) 
{ 
     Console.WriteLine(resp.StatusCode); 
}
