如何更快地获取HttpWebResponse返回信息的内容

// Create a 'WebRequest' object with the specified url.
WebRequest myWebRequest = WebRequest.Create();

// Send the 'WebRequest' and wait for response.
WebResponse myWebResponse = myWebRequest.GetResponse();

// Obtain a 'Stream' object associated with the response object.
Stream ReceiveStream = myWebResponse.GetResponseStream();

Encoding encode = System.Text.Encoding.GetEncoding("utf-8");

// Pipe the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader( ReceiveStream, encode );
Console.WriteLine("\nResponse stream received");
Char[] read = new Char[256];

// Read 256 charcters at a time.
int count = readStream.Read( read, 0, 256 );
Console.WriteLine("HTML...\r\n");

while (count > 0)
{
// Dump the 256 characters on a string and display the string onto the console.
String str = new String(read, 0, count);
Console.Write(str);
count = readStream.Read(read, 0, 256);
}

Console.WriteLine("");
// Release the resources of stream object.
readStream.Close();

// Release the resources of response object.
myWebResponse.Close();
