c# - Compare without generics -


There is a little problem to solve me.

I have a list of items, though later the list. Two of the examples will be filled in different types

The first type is MyFirstType & LT; T1, T2 & gt; and the other is MySecondType & LT; T & gt;

Now I need to run the list of objects and ask which of these items is there then I need to make some custom arguments on the item

example for:. 

  foreach (object obj in the list) {if (obj MyFirstType & lt; T1, T2 & gt;) {// do something} and if (obj is MySecondType & lt; ... {}} {}}   
 The problem can be T or T1 and T2 in any way, so how can I write such a thing - what is a keyword statement that only types the waiver of the forgiveness , But the generic is not inside?  If (obj MyFirstType & lt; T1, T2 & gt;)  does not work, because it needs solid type for T1 and T2  
 Just refer to T1 And need to compare without T2 .. How to solve any idea   
 
 
 You can use the property of  IsGenericType  If you can type  type , then check  obj.GetType ()  is normal and  GetGenericTypeDefinition  is the general type definition, which is To be used to get the typeof (MyFirstType & LT ;, & gt;)  and  typeof (MySecondType :  
  foreach (list obj) {if (obj .GetType () IsGenericType} {if (obj.GetType () GetGenericTypeDefinition () == typeof .. (MyFirstType & lt;; & gt;)) {// do something} else if (obj.GetGenericTypeDefinition () == typeof (MySecondType & lt; & gt;)) {}}}
