C# 将文档从ASP.Net上载到Sharepoint Server

我正在尝试将文件从ASP.Net上载到Sharepoint（为了保留时间戳，我使用这种方式）

下面是我的代码

    protected void UploadFileToSharePoint(string UploadedFilePath, string SharePointPath)
    {
        WebResponse response = null;

        try
        {
            string SUrl = "http://MysharepointPath/Folder";

            //WebRequest request = WebRequest.Create(SharePointPath);

            WebRequest request = WebRequest.Create(SUrl);

            request.Credentials = new NetworkCredential(username,password );

            //request.Method = "PUT";

            request.Method = "POST";

            FileStream fStream = File.OpenRead(UploadedFilePath);
            string fileName = fStream.Name.Substring(3);
            byte[] contents = new byte[fStream.Length];
            fStream.Read(contents, 0, (int)fStream.Length);

            fStream.Close();

            request.ContentLength = 0;

            //Custom code
            using (WebClient uploader = new WebClient())
            {
                try
                {
                    uploader.UploadFile(new Uri(SUrl), UploadedFilePath);
                }
                catch (Exception ex)
                {

                }
            }
            response = request.GetResponse();
        }
 }

当我尝试在调试模式下运行代码时，它会引发异常

“远程服务器返回错误401未经授权”

“为了保留时间戳，我用这种方式”是什么意思？SharePoint中上载文档的时间戳将是文档添加到SharePoint文档库的日期

错误401（Unauthorized）表示客户端必须首先对自身进行身份验证，因此您是否可以使用Fiddler验证您是否正在SharePoint服务器中进行身份验证

您是使用SharePoint Online还是内部部署

codeplex中有一些示例介绍了您试图实现的功能，请查看此链接以了解更多信息。。。
