HttpWebRequest 

The HttpWebRequest class allows you to programatically make web requests against an HTTP server. 

This code shows how to read a file's content from a remote webserver using the HttpWebRequest class.

Visual Basic:

If Not (IsPostBack) Then

    Try

        Dim fr As System.Net.HttpWebRequest

        Dim targetURI As New Uri("http://weblogs.asp.net/farazshahkhan")

 

        fr = DirectCast(System.Net.HttpWebRequest.Create(targetURI), System.Net.HttpWebRequest)

        'In the above code http://weblogs.asp.net/farazshahkhan is used as an example

        'it can be a different domain with a different filename and extension

        If (fr.GetResponse().ContentLength > 0) Then

            Dim str As New System.IO.StreamReader(fr.GetResponse().GetResponseStream())

            Response.Write(str.ReadToEnd())

            str.Close() 
        End If

 

    Catch ex As System.Net.WebException

        Response.Write("File does not exist.")

    End Try

End If

C#:

if (!(IsPostBack))

{

    try

    {

        System.Net.HttpWebRequest fr;

        Uri targetUri = new Uri("http://weblogs.asp.net/farazshahkhan");

        fr = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(targetUri);

        //In the above code http://weblogs.asp.net/farazshahkhan is used as an example

        //it can be a different domain with a different filename and extension

        if ((fr.GetResponse().ContentLength > 0))

        {

            System.IO.StreamReader str = new System.IO.StreamReader(fr.GetResponse().GetResponseStream());

            Response.Write(str.ReadToEnd());

            if (str != null) str.Close();

        }

    }

    catch (System.Net.WebException ex)

    {

        Response.Write("File does not exist.");

    }




}
