如何知道PropertyInfo是否爲ICollect <>類型 - Reflection和GenericType

Question

class Abc { 
    public Mycollection<Person> Persons { get;set; } 
} 

class MyCollection<T> : ICollect<T> { ... } 

我正在使用反射，獲取ABC.Persons的PropertyInfo。

我想知道PropertyInfo是否爲ICollect <> type - 我該怎麼做？

這似乎類似於：How To Detect If Type is Another Generic Type

public static bool IsAssignableToGenericType(Type givenType, Type genericType) { 
var interfaceTypes = givenType.GetInterfaces(); 

foreach (var it in interfaceTypes) 
    if (it.IsGenericType) 
     if (it.GetGenericTypeDefinition() == genericType) return true; 

Type baseType = givenType.BaseType; 
if (baseType == null) return false; 

return baseType.IsGenericType && 
    baseType.GetGenericTypeDefinition() == genericType || 
    IsAssignableToGenericType(baseType, genericType); 

}
