c# - 如何在属性中返回多个变量

Question

我想在一个属性中返回多个变量

public class Cars
{
    public object value { get; set; }
    public bool worked { get; set; }
}

public Cars GetCar(object value, Cars c)
{
   c.value = value;
   return c;
}

public void Main(string[] args)
{
   Cars c = new Cars();
   string mycar = "ABC-12";
   int mycar2 = 123;

   if (GetCar(mycar, c).value == "ABC") // working
       GetCar(mycar, c).worked = false;

   if (GetCar(mycar, c).value == 1) // error
       GetCar(mycar, c).worked = false;
}

所以如果对象是一个有效的字符串，但如果我使用那个 int，我会得到那个异常

The == operator can not be applied to "object" and "int" operands

注意:我不想每次都使用 Convert.to

您可以使用 object.Equals方法，这会将两个操作数首先转换为 object:

        if (object.Equals(GetCar(mycar, c).value,"ABC")) // working
            GetCar(mycar, c).worked = false;

        if (object.Equals(GetCar(mycar2, c).value,1)) // compiles, and does not throw exception
            GetCar(mycar2, c).worked = false;
