What WPF method gives the same KeyChar like in C#?

Question

in C#  there's a method KeyChar. when inserting a key in to a textBox it gives the value that was insert. for ex. when clicking on:5 the method gives: 5.
but Wpf doesn't have the KeyChar method.
i tried to use Key but then it gives me for ex. when i click: 5, i get: 5D5.
what method can i use to get the KeyChar like in C#?
or, maybe there's no such method and then i'll have to build one as an extension?

There is no KeyChar property in WPF. WPF is not Windows Forms. If you handle a keydown event there is only the Key property and this returns for example Key.D1 when you press a digit.
You could easily remove the "D" or the "NumPad" part using the string.SubString method though:
private void TextBox_PreviewKeyDown(object sender, KeyEventArgs e)
string number;
if ((e.Key >= Key.D0 && e.Key <= Key.D9))
//digit pressed!
number = e.Key.ToString().Substring(1); // = "1" when D1 is pressed
else if (e.Key >= Key.NumPad0 && e.Key <= Key.NumPad9)
number = e.Key.ToString().Substring(6); // = "1" when NumPad1 is pressed
else
//no digit...
Hope that helps.
