How do I get the text of the radio button selected item?

问题

Here are my radio buttons

Runescape
Maplestory
League

So this is my current method and it runs perfectly fine.

private void button1_Click(object sender, EventArgs e)
{
    if (radioButton1.Checked)
    {
        MessageBox.Show("You are playing Runescape.");
    }

    else if (radioButton2.Checked)
    {
        MessageBox.Show("You are playing Maplestory.");
    }

    else if (radioButton3.Checked)
    {
        MessageBox.Show("You are playing League.");
    }
}

I want to know if there is a way I can print out the SelectedItem kinda like a combo box. Basically, the text of the radio button.

Combobox version:

private void button1_Click(object sender, EventArgs e)
{
    MessageBox.Show("You are playing " + comboBox1.SelectedItem);
}

Something along the lines of this (not sure if it is possible).

MessageBox.Show("You are playing " + RadioButton.SelectedItem);

回答1:

you can use Text property of RadioButton .

private void button1_Click(object sender, EventArgs e)
    {
        if (radioButton1.Checked)
        {
            MessageBox.Show("You are playing "+radioButton1.Text);
        }

        else if (radioButton2.Checked)
        {
            MessageBox.Show("You are playing Maplestory "+"+radioButton2.Text);
        }

        else if (radioButton3.Checked)
        {
            MessageBox.Show("You are playing League "+"+radioButton3.Text);
        }
    }

Solution 2: there is no SelectedItem Property for RadioButton control.

but you can create a function which will return the Name of the selected RadioButton

Try this:

    private String getSelectedRadioButtonName()
     {
            foreach (Control c in groupBox1.Controls)
            {
                if (c is RadioButton && ((RadioButton) c).Checked==true)
                {
                    return c.Text;
                }
            }
            return "No Game";
      }
    private void button1_Click(object sender, EventArgs e)
    {

            MessageBox.Show("You are playing "+getSelectedRadioButtonName());
    }
