Question

这里有两个问题：

1）WebRequestMethods.Ftp.uploadfile和WebRequestMethods.Ftp.uploadfilewithuniquename之间的区别？

2）当我使用下面的代码为现有文件执行上传文件时，它会覆盖该文件。是否可以安全地假设它将始终覆盖？

         public static void Main ()
    {
        // Get the object used to communicate with the server.
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm");


        request.Method = WebRequestMethods.Ftp.UploadFile;
 // what if i use  request.Method = WebRequestMethods.Ftp.UploadFilewithuniquename;



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

        // Copy the contents of the file to the request stream.
        StreamReader sourceStream = new StreamReader("testfile.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();
        }

这些方法指的是FTP命令STOR and STOU。

如果登录用户拥有privs，则STOR（WebRequestMethods.Ftp.UploadFile）将创建一个新文件或覆盖现有文件。
