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.");

    }




}

The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.
 
The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
