On my current project I had the need to iterate through the properties of an object with reflection and to check if one of the properties is a generic List type, e.g. IList<int>, IList<Customer>, etc. To check through reflection on a generic type, you need to use the GetGenericTypeDefinition method.
Copy Codeforeach (PropertyInfo propertyInfo in entity.GetType().GetProperties())
{
if (propertyInfo.PropertyType.IsGenericType &&
typeof(List<>).IsAssignableFrom(propertyInfo.PropertyType.GetGenericTypeDefinition()))
{
IEnumerable enumerable = propertyInfo.GetValue(entity, null) as IEnumerable;
IEnumerator enumerator = enumerable.GetEnumerator();
while (enumerator.MoveNext())
{
// do something
}
}
}
