我们如何检查实现相等运算符的类型的引用相等性？

在 C# 中，我们如何检查实现相等运算符的类型的引用相等性？

class C
{
    public int Val{get;set;}
    public static bool operator ==(C c1, C c2)
    {
        return c1.Val == c2.Val;
    }
    public static bool operator !=(C c1, C c2)
    {
        return c1.Val != c2.Val;
    }
}
class Program
{
    public static void Main(string[] args)
    {
        C c1=new C(){Val=1};
        C c2=new C(){Val=1};
        Console.WriteLine(c1==c2);//True. but they are not same objects. 
                                  //How can I Check that?
        Console.Write("Press any key to continue . . . ");
    }
}

如果您的意思是通过引用相等，则可以使用Object.ReferenceEquals静态方法即使==运算符已重载以使当前类型正常工作，否则：

Object.ReferenceEquals(obj1, obj2);
