C# Reading Textbox ignoring characters

Question

Hi everyone i have a key down event as follows

if (e.KeyCode == Keys.C && e.KeyCode == Keys.Enter || e.KeyCode == Keys.Return)
{
    var amount = textBo         


        

Answer 1

Add e.SuppressKeyPress = true; e.Handled = true; to your handler when you want to prevent the key press from going forward.

As an aside, your if statement is equivalent to if (e.KeyCode == Keys.Return), since it will never be equal to both C and Enter.
