我猜我现在必须处理服务器发起的SSL信任问题,但如果这是真的,而不是2 Windows 7 Pro机器之间的不同,其中2个工作正常,2抛出该例外,异常在第一个“使用”:
使用(var os= firstrequest.getRequestStream())
例外详细信息:
System.Net.WebException was unhandled
Message=The operation has timed out
Source=System

它可以是什么?
public static string HttpPost4(string URI, string URI2, string Parameters1, string Parameters2)
{

CookieContainer cookieJar = new CookieContainer();

catch (Exception ee)

finally

}
. 解决方案
是 ssl证书问题,由服务器处理不佳。
重定向到其他服务器时,一切都在所有方案中都适用。
通过升级.NET 4到.NET 4.5
