當時的情況是這樣的：

a.aspx頁面執行一個URL字符串訪問b.aspx 然后 b頁面返回一個值給a

a.aspx.cs的一段代碼
代碼如下:
                            string result = "";
                            string url = "http://localhost:1759/textWeb/b.aspx";
                            result =exec_url(url);
                            Label1.Text = result;

public string exec_url(string url)
{

        string result = "1";
        WebRequest request = WebRequest.Create(url);
        try
        {
            request.Timeout = 20000;//20秒超時
            WebResponse response = request.GetResponse();

            Stream resStream = response.GetResponseStream();
            StreamReader sr = new StreamReader(resStream);
            result = sr.ReadToEnd();
            sr.Close();
            resStream.Close();
        }
        catch
        {
            return "1";
        }
        return result;

    }

b.aspx頁面代碼:
代碼如下:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>無標題頁</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>


    </div>
    </form>
</body>
</html>

b.aspx.cs代碼如下：
代碼如下:
public partial class test : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Write("你好哈哈！");
