在項目中用到了將WebClient上傳文件到服務(wù)器，經(jīng)在網(wǎng)上查找，自己添加到項目中進(jìn)行實(shí)驗了一番了，特將此代碼拷貝上來(lái)：

/// <summary>
        /// WebClient上傳文件至服務(wù)器
        /// </summary>
        /// <param name="localFilePath">文件名，全路徑格式</param>
        /// <param name="serverFolder">服務(wù)器文件夾</param>
        /// <returns></returns>
        public static bool Upload(string localFilePath, string serverFolder, string newFileName)
        {

                  //獲取服務(wù)器的IP
                 string ip = PublicMethod.GetIp();
                if (!serverFolder.EndsWith("/") && !serverFolder.EndsWith(@"\"))
                {
                    serverFolder = serverFolder + "/";
                }
                string uriString = "http://" + ip + "/" + serverFolder + newFileName;

                /// 創(chuàng )建WebClient實(shí)例
                WebClient myWebClient = new WebClient();
                myWebClient.Credentials = CredentialCache.DefaultCredentials;

                // 要上傳的文件
                FileStream fs = new FileStream(localFilePath, FileMode.Open, FileAccess.Read);
                ////判斷文件大小
                //string strFileSize = DAL.DataBaseOperator.GetValueFromApplictionConfig("fileSize");
                //int fileSize = Convert.ToInt32(strFileSize) * 1024 * 1024;
                //if (fs.Length > fileSize)
                //{
                //    MessageBox.Show("您上傳的附件不能超過(guò) " + strFileSize + "M");
                //    return false;
                //}
                BinaryReader r = new BinaryReader(fs);

                //使用UploadFile方法可以用下面的格式
                myWebClient.UploadFile(uriString, "PUT", localFilePath);
                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("文件目前不可寫(xiě)！");
                }
                System.Windows.Forms.Application.DoEvents();
                postStream.Close();
            }
            catch (Exception err)
            {
                MessageBox.Show("文件上傳失敗，請稍候重試~");
                //DAL.Log.FileLogSys.FileLog.WriteLog(err.Message + err.StackTrace);
                return false;
            }

            return true;

        }

/// <summary>

        public static string GetIp()
        {
            string Ip = "";

            string strConn = DBUtil.SqlConnectionManager.ConnectionString();

            int startIndex = strConn.IndexOf("=") + 1;
            int endIndex = strConn.IndexOf(";");
            int totalLength = strConn.Length;
