遇到问题查MSDN和google，这样解决得更快。
下面的代码来自MSDN Library:
// Create a new request to the mentioned URL.
HttpWebRequest myWebRequest=(HttpWebRequest)WebRequest.Create("http://www.microsoft.com");
WebProxy myProxy=new WebProxy();
// Obtain the 'Proxy' of the Default browser.
myProxy=(WebProxy)myWebRequest.Proxy;
// Print the Proxy Url to the console.
Console.WriteLine("\nThe actual default Proxy settings are {0}",myProxy.Address);
try
{
Console.WriteLine("\nPlease enter the new Proxy Address that is to be set:");
Console.WriteLine("(Example:http://myproxy.example.com:port)");
string proxyAddress;
proxyAddress =Console.ReadLine();
if(proxyAddress.Length>0)
{
Console.WriteLine("\nPlease enter the Credentials ");
Console.WriteLine("Username:");
string username;
username =Console.ReadLine();
Console.WriteLine("\nPassword:");
string password;
password =Console.ReadLine();
// Create a new Uri object.
Uri newUri=new Uri(proxyAddress);
// Associate the newUri object to 'myProxy' object so that new myProxy settings can be set.
myProxy.Address=newUri;
// Create a NetworkCredential object and associate it with the Proxy property of request object.
myProxy.Credentials=new NetworkCredential(username,password);
myWebRequest.Proxy=myProxy;
}
Console.WriteLine("\nThe Address of the new Proxy settings are {0}",myProxy.Address);
HttpWebResponse myWebResponse=(HttpWebResponse)myWebRequest.GetResponse();
//---------下面几行是我加的------
StreamReader reader= new StreamReader(myWebResponse.GetResponseStream());
string html = reader.ReadToEnd();
Console.WriteLine(html);
