Using .NET 3.5.

This does not work, how can I make it switch correctly?

Thanks.

[Flags]
public enum ColorModes
{
red = 2 ,
green = 4 ,
blue = 8
}

public class MyClass
{
public ColorModes CurrentMode{ get; set; }
public void Do()
{
ColorModes currentMode =
(ColorModes)Enum.Parse( typeof( ColorModes ) ,
this.CurrentMode.ToString() );
switch (currentMode)
{
case ColorModes.red:
break;
case ColorModes.green:
break;
case ColorModes.blue:
break;
}
}

One further comment. You defined ColorMode with the [Flags]
attribute, indicating that you expect to set more than one value at at
time. Your switch cases will only execute if there is a single color
flag set. It isn't clear if that is what you intend.

As Jon said, it's a really good idea to tell us how it doesn't work

In what way is it not working?

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

One comment - why are you taking a property which is already the right
type (CurrentMode), then converting the value to string and parsing it
back to the same type? Just use:

switch (CurrentMode)
