如何判断何时在 TextBox 中按下 Enter 键? [英] How do I tell when the enter key is pressed in a TextBox?

问题描述

基本上，我希望能够在按下 ENTER 键时触发事件.我已经试过了:

Basically, I want to be able to trigger an event when the ENTER key is pressed. I tried this already:

private void input_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Equals("{ENTER}"))
        {
            MessageBox.Show("Pressed enter.");
        }
    }

但 MessageBox 从未出现.我该怎么做?

But the MessageBox never shows up. How can I do this?

推荐答案

试试这个...

private void input_KeyDown(object sender, KeyEventArgs e) 
{                        
    if(e.KeyData == Keys.Enter)   
    {  
        MessageBox.Show("Pressed enter.");  
    }             
}
