Sample Code:
private delegate bool EnumDesktopsDelegate(string desktop, IntPtr lParam);
[DllImport("user32.dll")]
static extern bool EnumDesktops(IntPtr hwinsta, EnumDesktopsDelegate
lpEnumFunc, IntPtr lParam);
private static bool _enumDesktopCallback( string desktop, IntPtr lParam )
{
GCHandle gch = GCHandle.FromIntPtr( lParam );
IList<string> list = gch.Target as List<string>;
if ( null == list ) {
return (false);
}
list.Add( desktop );
return (true);
}
int _doEnumDesktops()
{
IList<string> list = new List<string>();
GCHandle gch = GCHandle.Alloc( list );
EnumDesktopsDelegate childProc = _enumDesktopCallback;
if (!EnumDesktops(IntPtr.Zero, childProc, GCHandle.ToIntPtr( gch ) ))
{
int e = Marshal.GetLastWin32Error();
WriteLine( "EnumDesktops errno={0}", e );
return 1;
}
foreach ( string a in list ) {
Console.WriteLine( a );
}
return 0;
