如何检测C#中的Tab键按下?

我想检测何时在文本框中按下Tab键，然后将面板中的下一个文本框聚焦.

I want to detect when tab key is pressed in a textBox and focus the next textbox in the panel.

我已经尝试过keyPressed方法和keyDown方法.但是，当我运行程序并调试时，按Tab键不会调用这些方法. 这是我的代码.

I have tried out keyPressed method and keyDown method. But when I run the program and debug those methods are not calling when the tab key is pressed. Here is my code.

private void textBoxName_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Tab)
    {
        textBoxUsername.Focus();
    }
}

private void textBoxName_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar==(char)Keys.Tab)
    {
        textBoxUsername.Focus();
    }
}

请纠正我.谢谢.
