C#winform怎么上传文件到服务器啊？

[lala133]

        private void UpLoadFile(string fileNamePath, string uriString)
        {
            //string fileName = fileNamePath.Substring(fileNamePath.LastIndexOf("\\") + 1);
            string NewFileName = DateTime.Now.ToString("yyMMddhhmmss") + DateTime.Now.Millisecond.ToString() + fileNamePath.Substring(fileNamePath.LastIndexOf("."));

            string fileNameExt = fileNamePath.Substring(fileNamePath.LastIndexOf(".") + 1);
            if (uriString.EndsWith("\\") == false) uriString = uriString + "\\";

            uriString = uriString + NewFileName;
            /**/
            /// 创建WebClient实例
            System.Net.WebClient myWebClient = new System.Net.WebClient();
           // WebClient myWebClient = new WebClient();
            
            //myWebClient.Credentials = CredentialCache.DefaultCredentials;

            // 要上传的文件
            FileStream fs = new FileStream(fileNamePath, FileMode.Open, FileAccess.Read);
            //FileStream fs = OpenFile();
            BinaryReader r = new BinaryReader(fs);
            try
            {
                //使用UploadFile方法可以用下面的格式
                //myWebClient.UploadFile(uriString,"PUT",fileNamePath);
                byte[] postArray = r.ReadBytes((int)fs.Length);
                Stream postStream = myWebClient.OpenWrite(uriString, "PUT");
                if (postStream.CanWrite)
                {
                    postStream.Write(postArray, 0, postArray.Length);
                }
                else
                {
                    MessageBox.Show("文件目前不可写！");
                }
                postStream.Close();
            }
            catch(Exception ex)
            {
                MessageBox.Show(ex .ToString ()+"文件上传失败，请稍候重试~");
            }
        }

每次到 postStream.Close();这里距出错了，服务器，我设置权限为everyone了，还是不行，请问用什么方法上传文件呢？

服务器上没网站 你怎么能用 System.Net.WebClient 来发送文件啊 用TCP或者FTP啊

局域网是可以发送文件成功的，服务器就不行。怎么用ftp啊？

我也是来学习的 求大神们各抒己见

[Trust-Me]

上传文件最蛋疼的莫过于程序没错，权限不够。

你可以现在自己机器上建一个FTP（好像要开启Window功能），先在本机上测试，google下C# ftp上传，有很多

这个就可以上传到服务器了，我已经测试了，怎么通过FTP删除文件和创建文件夹啊？

如果在ftp删除文件和创建文件夹？

[_小黑_]

删除 比较 麻烦 你需要 递归 先删除 最里面 的文件 之后 在 删除 文件夹 也就是 说 你不能 直接 删除 最外层的 文件夹 需要 冲内部 向 外部 删除

上传文件最蛋疼的莫过于程序没错，权限不够。

是啊，刚开始不知道，后面才知道。

虽然结贴了，我想说了你用的是FTP协议，在服务器上也有FTP服务端的，是不是，客户端不能随意发的而没有接收端
