This msdn page should do the trick - 检查按键中返回的keypresseventsargs或this keydown page应该允许您查询控制键(使用相关的.Net枚举)

在C#中,

       private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.ControlKey)
        {
            //Do some work
        }
    }
在VB.NET中

       Private  Sub textBox1_KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs)
            If e.KeyCode = Keys.ControlKey Then
                'Do some work'
            End If
       End Sub
