How do I determine the List<Object>'s object?

I am looking to create a generic method that receives a List. I need to determine what the object is within the list so that I can then do the necessary work according to the object that is being passed in within the list. How can I determine the kind of object that the List contains?

If the object type is not one of the generic parameters of your method then you can use the Type.GetGenericArguments method that returns the types of the parameters of a generic type (in your case List).

Else if the object type is one of the generic parameters of your method then use Travis J's answer.

given

List<T> objects;

you can get the type like this

var objType = typeof(T);

well you have the is keyword, which can compare objects

if(myObject is MyClass)
    doStuff();

you also have

typeof(myObject);

and as L.B. said, you have

obj.GetType() too
