Question

Is there a way to iterate (through foreach preferably) over a collection using reflection? I’m iterating over the properties in an object using reflection, and when the program gets to a type that is a collection, I’d like it to iterate over the contents of the collection and be able to access the objects in the collection.

At the moment I have an attribute set on all of my properties, with an IsCollection flag set to true on the properties that are collections. My code checks for this flag and if it’s true, it gets the Type using reflection. Is there a way to invoke GetEnumerator or Items somehow on a collection to be able to iterate over the items?

Answer 1

I had this issue, but instead of using reflection, i ended up just checking if it was IEnumerable. All collections implement that.

if (item is IEnumerable) {     foreach (object o in (item as IEnumerable))     {      } } else {    // reflect over item }
