What's an easy way to add Keys programatically?
-
I am working with a component which requires a System.Windows.Forms.Keys value. Right now, the only way I know how to change this value programatically, through user input, is:
if (input == "a")
{
key = Keys.A;
}
// ... keep goingI am sure there is an easier way to do this. Can someone help me out? Thanks in advance.

Is there a Keys.FromChar or something ? Is Keys an enum and Enum.Parse would do it ?

Well, if your in a Console Application then you can use
ReadKeywhich can tell you the key that was pressed.ConsoleKey thing = Console.ReadKey(true).Key;
The
truemeans that the key the user pressed will not be printed onto the screen. If you're in a Windows Application then set the formsKeyPreviewproperty totrueand use theKeyPressevent which will have data on the key that was pressed.My current favourite word is: I'm starting to run out of fav. words!

You want to use the Enum.Parse static method
public static object Parse( Type enumType, string value, bool ignoreCase );Applying this method to your example goes like this:key = (Keys)Enum.Parse(typeof(Keys), input, true);Don't forget to sanitize the input value. -

It doesn't always work (Unicode & foreign languages are the trickiest) but you can simply cast them:
key = (Keys)input;
I doubt it. If it isn't intuitive then we need to fix it. - Chris Maunder
I tried this and got
error CS0030: Cannot convert type 'string' to 'System.Windows.Forms.Keys' -
