TextBox已更改事件

Question

Instead of immediately calling function when text box is changed. I want to wait until a certain word is entered from a string. However the code I have written does not seem to work. Can anyone inform me f the correct approach to this.

private void txtConsole_TextChanged(object sender, EventArgs e)
    {
        string FastModeTest = "";
        if (FastModeTest.IndexOf("ADR=") > -1)
        {
            TestRoutine2();
        }
    }

Answer 1

private void txtConsole_TextChanged(object sender, EventArgs e)
{
     if (txtConsole.Text != "SOMEWORD")
        return;

    // rest
}

this code will cancel this function if certain key is not entered.
