I am currently trying to learn c# games programming.

i copied the following code from a book i have bought, and on the marked line it comes up with the error in the title of this thread. Any help as how to sort it?

c# code:

public class MainUiScreen : UiScreen, System.IDisposable
{
private Microsoft.DirectX.Direct3D.Texture buttonTextures = null;
private Microsoft.DirectX.Direct3D.Texture messageTexture = null;

private UiButton newButton = null;
private UiButton exitButton = null;

//events
public event System.EventHandler NewGame;
public event System.EventHandler Quit;

#region IDisposable Members
///<summary>
///clean up in case dispose isn't called
///</summary>
-MainUiScreen() \\it doesn't like the '-' on this line
{
Dispose();
}
///<summary>
///clean up any resources
///</summary>
...


if i remove the '-' it comes up with the error: no overload for method 'uiscreen' takes 0 arguments

please can someone help??

Thanks
