Hello, I am making a game called LINGO but I've run into a few problems. In our task we are only allowed to use the letters <A-Z>, anyone knows a good solution or code for that?

Best Regards Carl

you want user inputs to be restricted to A to Z only ?, kindly clarify

Yeah, sorry about that, in my text box I only want it to register the letters <a-z> any other letters like ÅÄÖ and special characters should not be registered and nothing should happened if I write them into the text box. Was that better explained?

What text box?! System.?.?...?.TextBox. Do you know there are more than one?
Tag you UI library: WPF, Forms, APS.MET, Silverlight, what?!

Solution 1

The most simple method I can think of is to create a string that contains the legal characters, and then check the input against that string

C#

string validChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

if (validChars.Contains(input[input.Length -1])
{
    // it's valid
}
