Changing Screen Resolution

I have a C# WPF application, I want it, when launched, to change the screen resolution if i开发者_JS百科t is not what it should work on, like the games.

I know how to retrieve the screen resolution, but I don`t know how to set it to what I want.

NOTE: I`m not working with ASP or WEB, just a desktop APP

This API function lets you change display settings:

        [DllImport("user32.dll")]
        static extern int ChangeDisplaySettings(
        ref DEVMODE devMode, int flags);

This article explains how to use this function

Why do you require this.

I think you should not do this, rather you can build the application within a ViewBox and which let you create Resolution Independent UI.
