此命令的FTP WebException-URI無效

Question

我有一段非常簡單的代碼。 一切都寫得正確，沒有錯別字，我跟同事聊天，但我們兩個人根本沒有理想，錯誤在這裏。

它順利地通過繼續彈出GetRequestStream（）異常彈出。它找到文件，正確編碼它，但似乎無法連接到服務器。

這是代碼：

public class WebRequestUploadExample 
{ 
    public void WebRequestUpload() 
    { 


    // Get the object used to communicate with the server. 
     FtpWebRequest request = (FtpWebRequest)WebRequest.Create(@"ftp://xxxxx"); 
     request.Method = WebRequestMethods.Ftp.UploadFile; 

     // This example assumes the FTP site uses anonymous logon. 
     request.Credentials = new NetworkCredential("xxxxx", "xxxxx"); 

     // Copy the contents of the file to the request stream. 
     StreamReader sourceStream = new StreamReader(@"D:\ftpTest\Test\Test.txt"); 
     byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd()); 
     sourceStream.Close(); 
     request.ContentLength = fileContents.Length; 

     Stream requestStream = request.GetRequestStream(); 
     requestStream.Write(fileContents, 0, fileContents.Length); 
     requestStream.Close(); 

     FtpWebResponse response = (FtpWebResponse)request.GetResponse(); 

     Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription); 

     response.Close(); 

    } 
}

可能是你的目標服務器不支持「被動」模式。你嘗試過主動模式嗎？ request.UsePassive = false;

FtpWebRequest.UsePassive
