checkbox如何取值并写入数据库?asp的~急求~

如果CheckBox处于选中状态，则为True，否则为False。默认值为False

实例：用CheckBox判断用户是否接受条款协议，如果用户没有选择，则不允许用户注册。单击“注册”按钮，触发btnreg_Click(object sender,EventArgs e)事件

protected void btnreg_Click(object sender, EventArgs e)

{

//判断用户是否接受条款协议

if (c1.Checked)

{

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["reg"].ConnectionString)

con.Open()

//定义用户注册的SQL语句

string cmdtex = "insert into users values('" + tname.Text + "','" + tpass.Text + "','" + tmail.Text + "')"

SqlCommand cmd = new SqlCommand(cmdtex, con)

try

{

cmd.ExecuteNonQuery()

con.Close()

Response.Write("<script>alert('注册成功！！')</script>")

}

catch (Exception err)

{

throw new System.Exception(err.Message)

}

}

else

{

Response.Write("<script>alert('请选择接受条款！！')</script>")

}

}

<input type="checkbox" name="aihao" value="1" ${news.aihao=='1'?'checked':''} readonly><input type="checkbox" name="aihao" value="2" ${news.aihao=='2'?'checked':''} readonly>这个里面必须是单引号
