Check What Letters are in a String

I am making a Hangman Game in C# in WPF, and I am wondering if there is a way to check what letters are in a string so that if a letter is choosen the program can determine if the letter is in the chosen word or not. Ex.

String StackOverFlow; //Sample String

//If Letter "A" is chosen,
private void AButt_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
//What Would I Put Here?
}

You can use ToLower() first to tackle case-sensitivity: StackOverflow.ToLower().Contains("a")

Use Contains:

StackOverFlow.Contains("A");

If you also want to know where in the word the letter first appears, you can use IndexOf:

StackOverFlow = "EXAMPLE"
StackOverFlow.IndexOf("A"); //returns 2
StackOverFlow.IndexOf("B"); //returns -1 because it is not present

You could use Contains(), but that is going to be case sensitive. Hangman is not.

The easiest way to handle that is to use IndexOf() instead:

if(StackOverFlow.IndexOf("A", StringComparison.CurrentCultureIgnoreCase) > -1)
{
    // Found
}
else
{
    // Not Found
}

You could use the String.Contais method. And don't create one event handler for each letter - create only one which checks what letter was input, then do something according to it existing in the string or not.
