webclient.uploadfile无法正常工作 [英] webclient.uploadfile not working

问题描述

我正在尝试将文件上传到asp.net 1.1 winforms应用程序中的远程服务器。我正在使用System.Net.WebClient方法上传文件。

但是，运行时出现以下错误：

" System.IO.IOException ：文件名，目录名称或卷标语法不正确。\\\\\ n  在System.IO .__ Error.WinIOError（Int32 errorCode，String str）\\\\ n  在System.IO.FileStream..ctor（String path，FileMode mode，
FileAccess access，FileShare share，Int32 bufferSize，Boolean useAsync，String msgPath，Boolean bFromProxy）\\ nn; 在System.IO.FileStream..ctor（String path，FileMode mode，FileAccess access，FileShare share）\\ nn;在System.Net.FileWebStream..ctor（FileWebRequest
请求，字符串路径，FileMode模式，FileAccess访问，FileShare共享）\\ n  在System.Net.FileWebRequest.InternalGetRequestStream（）"

这是我上传文件的代码：           

 
 System.Net.WebClient wc = new System.Net.WebClient（）; 
 wc.Credentials = new System.Net.NetworkCredential（uName，pwd）; 
 try 
 {
 Byte [] response = wc.UploadFile（@" \\ServerIP\C $ \Attachments\"，"POST"，txt_filename。文本）; 
} 
 catch（Exception ex）
 {
 exc = ex.InnerException.ToString（）; 
} 
 
请告诉我这里出了什么问题。
 
谢谢

txt_filename.Text < /跨度>

Hi,

I'm trying to upload files to a remote server in asp.net 1.1 winforms application. I'm using the System.Net.WebClient method to upload the file.

However, I'm getting the following error when I run it:

"System.IO.IOException: The filename, directory name, or volume label syntax is incorrect.\r\n\r\n   at System.IO.__Error.WinIOError(Int32 errorCode, String str)\r\n   at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean useAsync, String msgPath, Boolean bFromProxy)\r\n   at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share)\r\n   at System.Net.FileWebStream..ctor(FileWebRequest request, String path, FileMode mode, FileAccess access, FileShare sharing)\r\n   at System.Net.FileWebRequest.InternalGetRequestStream()"

Here's my code to upload the files:           

                System.Net.WebClient wc = new System.Net.WebClient();
                wc.Credentials = new System.Net.NetworkCredential(uName,pwd);
                try
                {
                    Byte[] response = wc.UploadFile(@"\\ServerIP\C$\Attachments\","POST",txt_filename.Text);
                }
                catch(Exception ex)
                {
                    exc = ex.InnerException.ToString();
                }
Please let me know what am doing wrong here.
Thank you
Abhi
