您可以使用所需的类型和相关名称来进行这样的重构，而不是在切换前的方法中使用带有lambda的valueX进行重构：

Action<float,float,Image> initialize
  = (value1,value2,value3,value4,value5,image) =>
  {
    var instance = new auto(value1,value5);
    price_result_lbl.Text = instance.getSetPrice.ToString(euro);
    weight_result_lbl.Text = instance.getSetWeight.ToString(kg);
    seats_result_lbl.Text = instance.getSetSeats.ToString();
    length_result_lbl.Text = instance.getSetLength.ToString(lenght);
    power_result_lbl.Text = instance.getSetPower.ToString(ps);
    modellView_img.Image = Image;
  };

您可以这样使用：

case "2er Coupé":
  initialize(30.700f,1.850f,5,4.461f,420,Properties.Resources._2erCoupé);
  break;

case "330e Limousine":
  initialize(51.550f,2.300f,4.709f,292,Properties.Resources._330eLimousine);
  break;

如果要获取自动实例：

Func<float,Image,auto> initialize
  = (value1,value5);
    price_result_lbl.Text = instance.getSetPrice.ToString(euro);
    weight_result_lbl.Text = instance.getSetWeight.ToString(kg);
    seats_result_lbl.Text = instance.getSetSeats.ToString();
    length_result_lbl.Text = instance.getSetLength.ToString(lenght);
    power_result_lbl.Text = instance.getSetPower.ToString(ps);
    modellView_img.Image = Image;
    return instance;
  };

您也可以创建本地方法或类方法，而不是lambda：

void or auto InitializeAutoAndControls(float value1,float value2,float value3,float value4,float value5,Image image)
{
  ...
}
