检测与反思本地对象 [英] detecting native objects with reflection

问题描述

我正与一个基于反射对象翻译。

I am working with a reflection based object translator.

它基本上遍历一个对象的属性，以及分配值属性具有相同名称/类型的翻译对象上。

it basically loops through properties of an object, and assigns the values to properties with the same name/type on the translated object.

ObjectA.Name =乔

语句：

ObjectB.Name =乔

我需要把一个特殊的情况下，当一个属性是一个自定义类，如：

I need to put a special case, for when a property is a custom class such as:

ObjectA.Address

我希望我能有IsClass标志属性类型

i was hoping i could detect such properties with IsClass flag of PropertyType

propInfo.PropertyType.IsClass

但这个标志也显得返回true字符串属性。

but this flag also appears to return true for string properties.

有另一种方式我可以验证属性是一种非原生类型的？

is there another way i could verify that the property is of a non native type?

推荐答案

我假设你要确定目标类型不是一颗灵长类动物。你也许可以使用键入code 对于这一点，例如：

I'm assuming you want to determine if the target type is not a primative. You can probably use TypeCode for that, for instance:

public bool IsNotCoreType(Type type)
{
    return (type != typeof(object) && Type.GetTypeCode(type) == TypeCode.Object);
}

任何非原始应该返回键入code.Object 的结果 Type.GetType code ，所以我们可以检查我们得到的，并且类型本身是不是 System.Object的。

Any non-primitive should return TypeCode.Object as the result of Type.GetTypeCode, so we can check that we get that and that the type itself is not System.Object.

也许这将帮助？

更新：我已经改名方法的 IsNotCoreType 的，既包括原语和非原语，如字符串，的DateTime 等（见下面的评论）。

UPDATE: I've renamed the method to IsNotCoreType to cover both primitives and non-primitives such as String, DateTime, etc. (see comments below).
