如何获得图片框的非公开成员的价值？ [英] How to get the value of non- public members of picturebox?

问题描述

我需要获得图像的矩形从图片框的非公共成员的值。

I need to get the value of Image rectangle from Non public members of picturebox.

如何获得这个值？

在此先感谢

推荐答案

这是如何得到的值，使用反射：

This is how to get the value, using reflection:

PropertyInfo pInfo = pictureBox1.GetType().GetProperty("ImageRectangle", 
    System.Reflection.BindingFlags.Public | 
    System.Reflection.BindingFlags.NonPublic | 
    System.Reflection.BindingFlags.Instance);

Rectangle rectangle = (Rectangle)pInfo.GetValue(pictureBox1, null);

虽然，作为乔恩说，有可能是实现你想要什么更好的方法做。通过反射访问私有成员通常是一个相当大的代码味道。

Although, as Jon has said, there may be a better way of achieving what you're trying to do. Accessing private members through reflection is usually a pretty big code smell.
