Question

I want to know if its possible to send a file to a generic handler in c#, and generate some kind of response. For example: post a .txt file to the handler. The handler check if a textfile is submitted and then converts it to json as response. Hope you get the idea. Thanks

You can write your handler like this:

public class FileUploadHandler : IHttpHandler 
{
    public void ProcessRequest (HttpContext context) 
    {
        HttpResponse response = context.Response;

        foreach (string file in context.Request.Files)  
        {  
           HttpPostedFile hpf = context.Request.Files[file] as HttpPostedFile;  
           if (hpf.ContentLength == 0)  
              continue; 
           //DO SOMETHING WITH FILE.
        }

        //RETURN ANY RESPONSE USING response OBJECT
    }

    public bool IsReusable 
    {
        get
        {
            return false;
        }
    }
}
