public static void UpLoadFile(string fileNamePath, string uriString)
{
string NewFileName = DateTime.Now.ToString("yyMMddhhmmss") + DateTime.Now.Millisecond.ToString() + fileNamePath.Substring(fileNamePath.LastIndexOf("."));
uriString = uriString + NewFileName;
//创建WebClient实例
WebClient myWebClient = new WebClient();
//指定用户名和密码
myWebClient.Credentials = new NetworkCredential("username", "password");
try

//上传文件
myWebClient.UploadFile(new Uri(uriString), fileNamePath);
