关于switch的问题

Question

 if (this.radioButton2.Checked)
            {
                this.skinEngine1.SkinFile = "EmeraldColor2.ssk";
                return;
            }
            else if (this.radioButton3.Checked)            {
                this.skinEngine1.SkinFile = "MidsummerColor2.ssk";
                return;
            }
            
请问下 如果要转成 switch的话怎么写。 radiobutton 没有 selectvalue属性啊。。

Answer 1

你是判断它是不是被选中...
用switch的话不如直接用if else呢  foreach (RadioButton rad in this.Controls)
            {
                switch (rad.Name)
                {
                    case "radioButton2":
                        if (radioButton2.Checked)
                        { this.skinEngine1.SkinFile = "EmeraldColor2.ssk";
                        }
                        break;
                    case "radioButton3":                }
            }

Answer 2

sting[] skins=new sting []{"",""EmeraldColor2.ssk","MidsummerColor2.ssk"};
radioButton1.Tag=0;
radioButton2.Tag=1;
radioButton3.Tag=2;                foreach (Control mycontrol in this.Controls)
                {
                    if (mycontrol.GetType() == typeof(RadioButton))
                    {
                        RadioButton myradio = mycontrol as RadioButton;                        
                        int index =(int) myradio.Tag;
                        if (myradio.Checked == true)
                        {
                            this.skinEngine1.SkinFile=skins[index];
                            break;
                        }
                    }
                }

switch与if并不能总是可以相互转换！

Answer 6

RadioButton rbtn = new RadioButton();
rbtn = (RadioButton)(this.rbtn1.Checked ? this.rbtn1 : (this.rbtn2.Checked ? this.rbtn2 : null));
switch(rbtn.Text)
{
      case "apple":this.txtFruit.Text = this.rbtn1.Text;
              break;
      case "pear":this.txtFruit.Text = this.rbtn2.Text;
              break;
      default:this.txtFruit.Text = "You choose nothing.";
              break;
}
