C#中回车键事件写法

１.private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
if(e.KeyValue==13)
{
MessageBox.Show("你摁下了回车");
}
}

２.public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.textBox1.KeyDown += new KeyEventHandler(textBox1_KeyDown);
this.button1.Click += new EventHandler(btnOK_Click);
}
void button1_Click(object sender, EventArgs e) { }
void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
this.button1_Click(button1, null); //在TextBox按Enter键就执行button1的单击事件
//如果你要用引发的话要用到api
}
}
}
