How do you programatically call an ashx file from dot.net?

Question

I have been provided with an ashx "service" that returns an image. I'm new to ashx files - so don't know how to handle it.

I need to stream the image into a byte[] so I can copy it somewhere else. How do I do that?

Answer 1

You can use WebClient.DownloadData pointing to asxh.

So let me give you a sample. Let's say you have image located on asp.net page, like this:

<img src="http://someServer/someSite/MyHandler.ashx?id=myId"/>

In this case you can use following code:

        using (System.Net.WebClient wclient = new System.Net.WebClient())
        {
            byte[] data = wclient.DownloadData(
                "http://someServer/someSite/MyHandler.ashx?id=myId");  
        }

Alternatively you can use WebRequest
