Set the Handled property of KeyPressEventArgs handler parameter to true.

将KeyPressEventArgs处理程序参数的Handled属性设置为true。

Example from msdn:

private void keypressed(Object o, KeyPressEventArgs e)
{
    if (e.KeyChar == (char)Keys.Return)

Do you mean, you want it to ignore the enter key ?

你的意思是,你希望它忽略输入键吗?

You could add a keydown event and ignore the enter key there...

你可以添加一个keydown事件并忽略那里的回车键......

private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            e.SuppressKeyPress = true;
        }
    }
