例如radiobutton 控件名为 rd1 再加一个text控件名字叫textbox3

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class 知道测试 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{

Boolean bl;
bl = RadioButton1.Checked;
int i;

if (bl == true)
{
i = 1;
}
else {
i=2;
}

switch (i) {
case 1:
{

TextBox3.Text ="这个case里面就可以写你想要执行的程序了。";
}

break;
}

}

}

Answer 2

int num=-1 ;

if (RadioButton1.Checked)
{
num = 1;
}
if (RadioButton2.Checked)
{
num = 2;
}
switch (num)
{
case 1: Response.Write("您选择RadioButton1"); break;
case 2: Response.Write("您选择RadioButton2"); break;
default:break;
}
