You can obtain member metadata for both unbound and closed generic types:
using System;
using System.Reflection;
using System.Collections.Generic;
class Program
{
static void Main()
{
PropertyInfo unbound = typeof(IEnumerator<>).GetProperty("Current");
PropertyInfo closed = typeof(IEnumerator).GetProperty("Current");
Console.WriteLine(unbound); // T Current
Console.WriteLine(closed); // Int32 Current
Console.WriteLine(unbound.PropertyType.IsGenericParameter); // True
Console.WriteLine(closed.PropertyType.IsGenericParameter); // False
}
}
The output:
T Current
Int32 Current
True
False
