我写的一个在.NET下获取网页内容的类：
using
System;
using System.Net;
using System.IO;
using System.Text;
using System.Windows.Forms;
namespace iUNS
{
/// <summary>
/// iuGetWebContent 的摘要说明。
/// </summary>
public class iuGetWebContent
{
public iuGetWebContent()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
/// <summary>
/// 从指定的url取得网页内容
/// </summary>
/// <param name="url"> 网页地址 </param>
/// <returns> 返回取得的内容 </returns>
public static string getContentFromUrl( string url, string encoding)
{
try
{
string text = "" ;
// Create a 'WebRequest' object with the specified url.
WebRequest myWebRequest = WebRequest.Create(url);
myWebRequest.Timeout = 10000 ;
// 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(encoding);
// 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[ 512 ];
// Read 512 charcters at a time.
int count = readStream.Read( read, 0 , 512 );
// Console.WriteLine("HTML
\r\n");
while (count > 0 )
{
// Dump the 512 characters on a string and display the string onto the console.
String str = new String(read, 0 , count);
text += str;
count = readStream.Read(read, 0 , 512 );
}
// Release the resources of stream object.
readStream.Close();
// Release the resources of response object.
myWebResponse.Close();
return text;
}
catch
{
return " MYERROR " ;
}
}
}
}
