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.

        }

    }

}
