我怎么知道PropertyInfo是否属于ICollect＆lt;＆gt; type - Reflection和GenericType

Question

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

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

我正在使用反射，获取ABC.Persons的PropertyInfo。

我想知道PropertyInfo是否属于ICollect＆lt;＆gt;类型 - 我该怎么做？

这类似于：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);

}
