Check if an object is a type of collection, regardless of what Type that collection is of?

Question

I can check for a single type by using

if (e.PropertyType == typeof(EntityCollection<Search_SearchCodes>))

But but I really want to avoid all objects that are EntityCollections

if (e.PropertyType == typeof(EntityCollection))

Is there a way to do this?

@Servy: IIRC (which I rarely do), `EntityCollection` is `sealed`. — Chris Sinclair, Sep 13 '13 at 20:07

You can do this by confirming that the type is a generic type, and its generic type definition is equal to the EntityCollection<> open generic type.

var type = e.PropertyType;
var isEntityCollection = type.IsGenericType && 
    type.GetGenericTypeDefinition() == typeof(EntityCollection<>);

Excellent, that works great. Also, it never occurred to me that you can use multiple conditionals when assigning a boolean, so I learned two cool things, thanks! – cost Sep 13 '13 at 20:14
