在C# 中使用反射调用internal的属性

有些类型的属性的Set方法被标注为了internal, 或private, 我们外部无法对其进行调用, 这时可以使用反射的方法调用到它.

举例如下:

使用反射的方法代码

public void test()
{
        Assembly asm = Assembly.LoadFile(@"C:\ISAPI\MyPublishing.dll");
        Type publishingType = asm.GetType("MyPublishingNameSpace.PublishingType");
        ConstructorInfo publishingTypeConstructor = 
            publishingType.GetConstructor(Type.EmptyTypes);
        Object oPubClass = publishingTypeConstructor.Invoke(new Object[] { });


        foreach (PropertyInfo rInfo in publishingType.GetProperties())
        {
            if (rInfo.Name == "PropertyName")
            {
                if (rInfo.CanWrite)
                {
                    rInfo.SetValue(oPubClass, "NewPropertyValue", null);
                }
                break;
            }
        }

        MyPublishingNameSpace.PublishingType ptObj =
                    (MyPublishingNameSpace.PublishingType)oPubClass;
        //Save your reflection work.
        ptObj.Searilize();
}

 

被反射的类型的源码

namespace MyPublishingNameSpace
{
    public class PublishingType
    {
        private string _property1 = string.Empty;
        public PublishingType() { }
        public string PropertyName
        {
            get { return _property1;}
            internal set { _property1 = value;}
        }
        public void Searilize()
        {
            //Save object.
        }
    }
}
