Displaying ad content from Respose.WriteFile()/ Response.ContentType *

Question

How would one display any add content from a "dynamic" aspx page? Currently I am working on using the System.Web.HttpResponse "Page.Response" to write a file that is stored on a web server to a web request.

This would allow people to hit a url to the type http://www.foo.com?Image=test.jpg and have the image display in their browser. So as you may know this revolves around the use of Response.ContentType.

By using

Response.ContentType = "application/octet-stream";

I am able to display images of type gif/jpeg/png (all i have tested so far), bit trying to display .swf or .ico files gives me a nice little error.

using

Response.ContentType = "application/x-shockwave-flash";

I can get flash files to play, but then the images are messed.

So how do i easily choose the contenttype?

Answer

This is ugly, but the best way is to look at the file and set the content type as appropriate:

switch ( fileExtension )
{
    case "pdf": Response.ContentType = "application/pdf"; break; 
    case "swf": Response.ContentType = "application/x-shockwave-flash"; break; 

    case "gif": Response.ContentType = "image/gif"; break; 
    case "jpeg": Response.ContentType = "image/jpg"; break; 
    case "jpg": Response.ContentType = "image/jpg"; break; 
    case "png": Response.ContentType = "image/png"; break; 

    case "mp4": Response.ContentType = "video/mp4"; break; 
    case "mpeg": Response.ContentType = "video/mpeg"; break; 
    case "mov": Response.ContentType = "video/quicktime"; break; 
    case "wmv":
    case "avi": Response.ContentType = "video/x-ms-wmv"; break; 

    //and so on          

    default: Response.ContentType = "application/octet-stream"; break; 
}
