ReSharper建议我们改变：
System.Net.ServicePointManager.ServerCertificateValidationCallback +=
delegate(object sender,X509Certificate certificate,X509Chain chain,SslPolicyErrors sslPolicyErrors)
{
return true;
};
成：
System.Net.ServicePointManager.ServerCertificateValidationCallback +=
(sender,certificate,chain,sslPolicyErrors) => true;
它看起来更清洁.但我们的目标是.NET 2.0.这仍然是我们应该做的事情吗？
