因此，我之前使用过托管的 SharePoint 网站，当我使用以下代码对该网站进行身份验证时，一切正常：
private static NetworkCredential credentials = new NetworkCredential(username, password, domain);
private static ClientContext clientContext = new ClientContext("https://thisonesite.com/hosting/151");
private static Web site = clientContext.Web;
private static List list = site.Lists.GetByTitle(listName);
private static void sharepointLogin()
{
try
{
//Loads credentials needed for authentication
clientContext.Credentials = credentials;
//Loads the site
clientContext.Load(site);
//Loads the site list
clientContext.Load(list);
//Executes the previous queries on the server
clientContext.ExecuteQuery();
//Writes out the title of the SharePoint site to the console
Console.WriteLine("Title: {0}", site.Title);
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
现在，我为我创建了一个沙箱，我可以（手动）访问该站点。但是，当我尝试通过我的 c# 代码对站点进行身份验证时，出现错误。
除了用户名、密码和域之外，我真正改变的只是private static ClientContext clientContext = new ClientContext("http://sandbox");.
我在控制台中得到的错误是：
System.Net.WebException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

有谁知道为什么在新的 SharePoint 网站上突然出现此错误？
