Question

How to make this works? :

private string KeyChar = "";

public void SetMyKey(object sender, KeyEventArgs e) {
     KeyChar = e.KeyCode; //ERROR
}

public void MyKeyDown(object sender, KeyEventArgs e) {
     if (e.KeyCode = Keys.KeyChar) { //ERROR
          Function();
     }
}

Instead of using a method, I would use a property – you’ll also want to use the correct type here (Keys, instead of string). In addition, you need to use == to check equality, since = is for assignment in C#:

public Keys KeyChar { get; set; }

public void MyKeyDown(object sender, KeyEventArgs e) {
    if (e.KeyCode == this.KeyChar) {
        Function();
    }
}
