C# - 构造函数和继承

我有两个类声明如下:

class Object1
{
    protected ulong guid;
    protected uint type;

    public Object1(ulong Guid, uint Type)
    {
        this.guid = Guid;
        this.type = Type
    }
    // other details omitted
}

class Object2 : Object1
{
    // details omitted
}

在客户端代码中,我希望能够像这样创建每个对象的实例:

Object1 MyObject1 = new Object1(123456789, 555);
Object2 MyObject2 = new Object2(987654321, 111);

我怎样才能让Object2像这样使用Object1的构造函数？谢谢.

class Object2 : Object1
{
   Object2(ulong l, uint i ) : base (l, i)
   {
   }
}
