有没有人知道我如何设置访问不同的服务器文件夹与用户名和密码在c# .net

这里有一个简短的问题。有谁能告诉我如何在c# .net中使用用户名和密码设置访问差异服务器文件夹吗?

我有下面的代码上传一个文件到另一个服务器的文件夹。不知何故，我需要使用用户名和密码，然后我只能访问到这个文件夹。有人知道设置文件夹访问用户名和密码的代码吗?

   private void uploadFile()
   {
           DateTime dateTime = DateTime.Now;
           string sDate = dateTime.ToString("yyyyMMdd") + "_" + dateTime.ToString("fffffff");
           string fn = System.IO.Path.GetFileName(File1.PostedFile.FileName);
           string SaveLocation = Server.MapPath("document") + "''" + sDate + "_" + fn;
           supportFileName = sDate + "_" + fn;
           try
           {
               File1.PostedFile.SaveAs(SaveLocation);
           }
           catch (Exception ex)
           {
               err.Text = "Error: " + ex.Message;
           }
   }

用于访问不同的服务器，并将文件上传到其中。首先，您需要为这个用户帐户赋予正确的权限，并模拟这个帐户。

在编程上下文中，术语"模拟"是指在另一个用户上下文中执行代码，而不是在最初启动应用程序的用户上下文中执行代码的技术，即在应用程序执行期间，用户上下文中临时更改一次或多次。

这里有两篇文章，希望能对大家有所帮助，有样例代码:
