Find a private field with Reflection?(使用反射找到一个私有字段?)

本文介绍了使用反射找到一个私有字段?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

Given this class

class Foo
{
    // Want to find _bar with reflection
    [SomeAttribute]
    private string _bar;

    public string BigBar
    {
        get { return this._bar; }
    }
}

I want to find the private item _bar that I will mark with a attribute. Is that possible?

I have done this with properties where I have looked for an attribute, but never a private member field.

What are the binding flags that I need to set to get the private fields?

解决方案

Use BindingFlags.NonPublic and BindingFlags.Instance flags

FieldInfo[] fields = myType.GetFields(
                         BindingFlags.NonPublic | 
                         BindingFlags.Instance);
