使用c#编写APP上传文件到sharepoint2013出错

[starseeker7]

如题，一个曾经正常使用的代码
因公司把sharepoint2003升级到了2013，这个客户端程序就无法使用了- -
提示错误"The remote server returned an error: (403) Forbidden.“

            try
            {
                using (WebClient IR = new WebClient())
                {
                    IR.Credentials = new NetworkCredential("username", "pwd", "域名");
                    IR.UploadFile(@"http://sitename/file/filename.xml", "put", @"F:\File\filename.xml");
                }

            }
            catch (System.Net.WebException webex)
            {
                MessageBox.Show("Update File Error(System.Net.WebException):" + webex.Message.ToString());
            }
            catch (Exception ex)
            {
                MessageBox.Show("Update File Error(System.Exception):" + ex.Message.ToString());
            }

网上查询了参考资料

但按照他提供的代码会提示无法调用Microsoft.SharePoint.Client.Runtime的情况
求各位大大解惑，谢谢
