确定 FieldInfo 是否是编译器生成的后台字段 [英] Determine if FieldInfo is compiler generated backingfield

问题描述

标题几乎说明了一切，我怎么知道我是否正在为 {get;设置;} 属性?

The title pretty much says it all, how do I know if I'm getting a compiler generated backingfield for a {get; set;} property ?

我正在运行此代码以获取我的 FieldInfos:

I'm running this code to get my FieldInfos:

Class MyType
{
    private int foo;
    public int bar {get; private set; }
}

Type type = TypeOf(MyType);
foreach (FieldInfo fi in type.GetFields(BindingFlags.Instance | BindingFlags.Public | BindingFlags.DeclaredOnly | BindingFlags.NonPublic))
{
    // Gets both foo and bar, however bar is called <bar>k__backingfield.
}

所以问题是，我能否以某种方式检测到 FieldInfo 是一个后台字段，而不依赖于检查其名称?(这是相当无证的，可能会在框架的下一个版本中被破坏)

so the question is, can I somehow detect that the FieldInfo is a backingfield, without relying on checking its name ? (Which is pretty undocumented, and could be broken in next version of the framework)

推荐答案

检查 .IsDefined(typeof(CompilerGeneratedAttribute), false); 对它们.
