C# 中关于radiobutton控件的使用

在一个Form窗口中定义了3个radiobutton，radioButton1、radioButton2和radioButton3，以及button1和button2(这里可以是其他控件)

为了实现单击radioButton1时，button1显示"A1"，button2显示"A2";

单击radioButton2时，button1显示"B1"，button2显示"B2";

单击radioButton3时，button1显示"C1"，button2显示"C2".

下面代码就可以实现这个功能：

private void radioButton1_CheckedChanged(object sender, EventArgs e) 
{
    if(radioButton1.Checked == true)
    {
        button1.Text == "A1";
        button2.Text == "A2";
    }
    if(radioButton2.Checked == true)
    {
        button1.Text == "B1";
        button2.Text == "B2";
    }
    if(radioButton3.Checked == true)
    {
        button1.Text == "C1";
        button2.Text == "C2";
    }
}
