Question

I have 2 radio button for gender. one male (named radMale ) one female (name radFemale ). lets say a user clicks the "male" button. how do i display what he chose on a MessageBox ?

MessageBox.Show(radMale = "Male");

I know this doesn't work, does anyone know which code will?

Answer 1

I tried executing the following code which might solve your problem.

public partial class Form1: Form
{
        public Form1()
        {
            InitializeComponent();
            this.Load += new EventHandler(Form1_Load);
            radioButton1.CheckedChanged += new EventHandler(radioButton_CheckedChanged);
            radioButton2.CheckedChanged += new EventHandler(radioButton_CheckedChanged);
        }

        void radioButton_CheckedChanged(object sender, EventArgs e)
        {
            RadioButton rb = (RadioButton)sender;
            if(rb.Checked)
                MessageBox.Show(rb.Text); //Shows whatever Text your radiobutton has
        }

        void Form1_Load(object sender, EventArgs e)
        {

        }
}

在WinForms中，使用此：

MessageBox.Show(radMale.Checked?"Male":"Female");
