Question

I’ve been looking around for this for awhile. I would like to know how to get the type of the template passed into creating a list. For example.

List<string> listOfStrings = new List<string>();

How would I get the string type from this? I know how to use the type to get the fields and find the list type but not the template within it.

Answer 1

In this instance, you can get it like this

Type genericType = listOfStrings.GetType().GetGenericArguments()[0];

Note that if you try this on a non generic type, it will fail because the length of the GetGenericArguments array will be 0, but you can of course take measures to control the length of the array.
