使用C＃

Question

使用c＃连接到tfsapi时出现以下错误。我有正确的凭据，url并添加了dll Microsoft.TeamFoundation.Client C：\ Program Files（x86）\ Microsoft Visual Studio 10.0 \ Common7 \ IDE \ ReferenceAssemblies \ v2.0

＆安培; System.Net也是。有什么可能导致这个问题的建议吗？

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using Microsoft.TeamFoundation.Client;


namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Uri url = new Uri("https://");

            NetworkCredential nc = new NetworkCredential("", "", "");

            TfsTeamProjectCollection coll = new TfsTeamProjectCollection(url, nc);

            coll.EnsureAuthenticated();

        }
    }
}

错误： “Microsoft.TeamFoundation.Clientdll中发生了'System.Net.WebException'类型的未处理异常。附加信息：底层连接已关闭.Cound未建立SSL / TSL安全通道的信任关系”
