XMLHTTP获得网页内容的方法(C#版)

首先需要在项目中添加(Microsoft XML, v3.0)的引用

using MSXML2;

private string VerifyNotifyURL(string URL)
{
    MSXML2.XMLHTTPClass xmlhttp=new MSXML2.XMLHTTPClass();
    try
    {
        xmlhttp.open("GET",URL,false,null,null);
        xmlhttp.setRequestHeader("CONTENT-TYPE","text/xml;charset=gb2312");
        xmlhttp.send(null);
        return System.Text.Encoding.GetEncoding("gb2312").GetString((byte[])xmlhttp.responseBody);
    }
    catch
    {
        return "";
    }
}
