Question

Following program will connect to the web and get html content of “msnbc.com” webpage and print out the result. If it takes longer than 2 seconds to get data from the webpage, I want my method to stop working and return. Can you please tell me how can I do this with an example?

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        gethtml();
        MessageBox.Show("End of program");
    }

    public void gethtml()
    {
        HttpWebRequest WebRequestObject = (HttpWebRequest)HttpWebRequest.Create("http://msnbc.com/");

        WebResponse Response = WebRequestObject.GetResponse();
        Stream WebStream = Response.GetResponseStream();

        StreamReader Reader = new StreamReader(WebStream);
        string webcontent = Reader.ReadToEnd();
        MessageBox.Show(webcontent);
    }
}

As stated above .Timeout

    public void gethtml()
    {
        HttpWebRequest WebRequestObject = (HttpWebRequest)HttpWebRequest.Create("http://msnbc.com/");
        WebRequestObject.Timeout = (System.Int32)TimeSpan.FromSeconds(2).TotalMilliseconds;
        try
        {
            WebResponse Response = WebRequestObject.GetResponse();
            Stream WebStream = Response.GetResponseStream();

            StreamReader Reader = new StreamReader(WebStream);
            string webcontent = Reader.ReadToEnd();
            MessageBox.Show(webcontent);
        }
        catch (System.Net.WebException E)
        {
            MessageBox.Show("Fail");
        }
    }
