如何獲得單選按鈕所選項目的文本？

Question

這是我的單選按鈕

Runescape
Maplestory
League

所以這是我當前的方法，它運行得很好。

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.");
    }
}

我想知道是否有一種方法可以像組合框一樣打印出SelectedItem。 基本上是單選按鈕的文本。

組合框版本：

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

與此類似的東西（不確定是否可能）。

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

Answer 1

您可以使用RadioButton Text屬性。

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);
        }
    }

解決方案2： RadioButton控件沒有SelectedItem屬性。

但是您可以創建一個function ，該function將返回所選RadioButton的Name

嘗試這個：

    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());
    }
