the best way to make a collection of types and check against it

Question

how can i make a collection that can store a data type (say string, datetime, decimal, etc..)? and that use this collection to perform comparison as such:

if (pi.PropertyType.IsIn ([how can check against the collection of type) //where pi is a property info]))
{

}

any suggestions?

Answer 1

List<Type> types = new List<Type> {typeof(string), typeof(int)};
if (types.Contains(pi.PropertyType))
{
  //do stuff
}
