我试图沿着下面的代码的东西运行在Windows Server 2012 R2机器上的C#的Web客户端应用程序:权限问题与.NET的Web客户端应用程序
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
namespace willitwork
{
class Program
{
static void Main()
{
// Create web client.
WebClient client = new WebClient();
// Download string.
string value = client.DownloadString("http://www.dotnetperls.com/");
// Write values.
Console.WriteLine("--- WebClient result ---");
Console.WriteLine(value.Length);
Console.WriteLine(value);
}
}
}
当我运行应用程序作为管理员一切工作正常:
C:\moop>whoami
p10uc2\administrator
C:\moop>willitwork.exe
--- WebClient result ---
3336
<!doctype html><html><head><link rel=canonical href=http://www.dotnetperls.com><style>body{font:18px/1.45 verdana;position:relative;padding:0 0 330px;min-width:
750px;max-width:960px;margin:0 auto}...
etc.
但是,部署时,应用程序将由系统启动。我切换到系统的用户,并再次运行应用程序,刚要碰到这样的:
c:\moop>whoami
nt authority\system
c:\moop>willitwork.exe
Unhandled Exception: System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made becaus

出于某种原因,这似乎并没有要在Windows 7的问题,我会是什么任何暗示感激我可能做错了!
