我晕,怎么接收端 怎么可能啊。你这是所谓往局域网别的机器发送文件,那么也得给他的一个物理地址啊uriString 你传的什么参数

服务器上传的位置。
我们可以发送任何一个文件到 腾讯服务器喽...甚至病毒文件....
http://blog.163.com/lewei8@yeah/blog/static/7327417020111120103515205/
说明你上传文件用的协议是HTTP啊
服务器端就得用Request.Files接收
这样子服务器也接收不了啊?
服务器段是用网站开发的啊 不是WINFORM客户端核心代码 System.Net.WebClient myWebClient = new System.Net.WebClient();
myWebClient.UploadFile("http://wwww.xxx.com","客户端的文件路径");看你代码 写那么复杂不知道干嘛用的

System.Net.WebClient 来发送文件啊
用TCP或者FTP啊

局域网的那台机器是不是建了一耳光共享文件夹吧,如果是的那不叫夸机器传送文件的 ,再说了,局域网和外网差别大了
这是答案
需要注意的是:设置好FTP的权限
