Question

如果单击button3，它应该对11个radiobutton中的一个执行单击。这个程序有效，但我想知道是否有更短的输入方式。

我想知道，因为如果我想用50个无线电按钮做这个，那么这将是一个极长的。

    private void button1_Click(object sender, EventArgs e)
    {
        Random RandomRadioButton = new Random();
        int Simuleer = RandomRadioButton.Next(0, 12);

        if (Simuleer == 0) { radioButton0.PerformClick(); }
        if (Simuleer == 1) { radioButton1.PerformClick(); }
        if (Simuleer == 2) { radioButton2.PerformClick(); }
        if (Simuleer == 3) { radioButton3.PerformClick(); }
        if (Simuleer == 4) { radioButton4.PerformClick(); }
        if (Simuleer == 5) { radioButton5.PerformClick(); }
        if (Simuleer == 6) { radioButton6.PerformClick(); }
        if (Simuleer == 7) { radioButton7.PerformClick(); }
        if (Simuleer == 8) { radioButton8.PerformClick(); }
        if (Simuleer == 9) { radioButton9.PerformClick(); }
        if (Simuleer == 10) { radioButton10.PerformClick(); }
        if (Simuleer == 11) { radioButton11.PerformClick(); }
    }

Answer 1

如果是WinForms，请尝试以下操作：

string name = string.Format("radioButton{0}", Simuleer);
this.Controls/* or container that groups thease radio buttons */
             .OfType<RadioButton>().FirstOrDefault(ctrl => ctrl.Name == name).PerformClick();

这有点长，但这段代码将来很容易维护。

将RadioButtonList与Separate Radio buttons进行比较。

        protected void Button1_Click(object sender, EventArgs e)
        {
            Random random = new Random();

            var radioButtonNumber = random.Next(RadioButtonList1.Items.Count);

            RadioButtonList1.SelectedIndex = radioButtonNumber;

            RadioButtonListClick(radioButtonNumber);

        }

        private void RadioButtonListClick(int number)
        {
            switch (number)
            {
                case 0:
                    // Call the function realted to radio button 0 in your case.
                    break;
                    .
                    .
                    .

            }
        }

注意：这将确保在编译时此代码在运行时不会失败。与确保radiobutton id应该相同并且如果找不到它相比，它会抛出运行时错误。
