compare two object

[Locia]

How can I understand if two object obj1 and obj2 have same type?

Can I do: if (obj1.GetType()==obj2.GetType()) return true;?

Moto u1;
Moto u2;

I call Compare(u1,u2,">")

class Moto have override operator >.

How can I use reflection in Compare fuction to call operator > of Moto
class to compare u1 and u2?
bool Compare(Object obj1,Object obj2,String Operator)
{

.....?
}

Absolutely.
Moto u1;
Moto u2;

I call Compare(u1,u2,">")

class Moto have override operator >.

MethodInfo method = typeof(Moto).GetMethod("op_GreaterThan",
BindingFlags.Public |
BindingFlags.Static);

That seems to work, although I don't know to what extent it's
guaranteed...

Yes you can do:

if (obj1.GetType()==obj2.GetType())

And For comparing check out the IComparable interface and the Compare
pattern in .Net:

I can't use "typeof(Moto)" in Compare function because u1 and u2 can be
two instance of another class.

Another way?

u1 and u2 are generic object.
Another way?

Call GetType() on u1 then.
