KeysConverter Class

Provides a TypeConverter to convert Keys objects to and from other representations.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public class KeysConverter : TypeConverter, 

Most commonly, the KeysConverter type converter is used to convert Keys instances to and from their corresponding localized String representations.

The following code example demonstrates how to use the KeysConverter class to convert a KeyCode to a String. This example assumes that you have a TextBox named TextBox1 on a Form named Form1.

public partial class Form1 : Form
    public Form1()

        this.textBox1.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.KeyPressWork);
        this.textBox1.KeyDown += new System.Windows.Forms.KeyEventHandler(this.KeyDownWork);

    private void KeyDownWork(object sender, KeyEventArgs e)
        MessageBox.Show(e.KeyCode.ToString(), "KeyDown");

        KeysConverter kc = new KeysConverter();
        MessageBox.Show(kc.ConvertToString(e.KeyCode), "KeyDown");

    private void KeyPressWork(object sender, KeyPressEventArgs e)
        MessageBox.Show(e.KeyChar.ToString(), "KeyPress");
