如何使用不同的单选按钮更改 tabcontrol 索引？ C＃

Question

private void radioButtons_CheckedChanged(object sender, EventArgs e)
    {
        RadioButton radioButton = sender as RadioButton;
        if (radioButton1.Checked) tabControl1.SelectedIndex = 0;
        else if (radioButton2.Checked) tabControl1.SelectedIndex = 1;
        else if (radioButton3.Checked) tabControl1.SelectedIndex = 2;
        else if (radioButton4.Checked) tabControl1.SelectedIndex = 3;
        else if (radioButton5.Checked) tabControl1.SelectedIndex = 4;
        else if (radioButton6.Checked) tabControl1.SelectedIndex = 5;
        else if (radioButton7.Checked) tabControl1.SelectedIndex = 6;
        else if (radioButton8.Checked) tabControl1.SelectedIndex = 7;
    }

如您所见，我正在使用 EventHandler() 更改带有单选按钮的标签页。我想知道，我怎样才能简化这个“else if”结构。可能我需要一个 foreach()，但我找不到答案。

您可以为每个与索引绑定的单选按钮设置Tag。

radioButton1.Tag = 0;
radioButton2.Tag = 1;
...

RadioButton radioButton = sender as RadioButton;
if(radioButton.Checked)
    tabControl1.SelectedIndex = (int)radioButton.Tag;
