如何将字符转换为等效的System.Windows.Input.Key枚举值？

using System;
using System.Windows.Input;

class Program
{
    static void Main(string[] args)
    {
        char c = 'A';
        Key key = KeyInterop.VirtualKeyFromChar(c);
        Console.WriteLine("The System.Windows.Input.Key equivalent for the character '{0}' is {1}", c, key);
    }
}

The System.Windows.Input.Key equivalent for the character 'A' is A
