Type.GetMethods的BindingFlags(不包括属性访问器) [英] BindingFlags for Type.GetMethods excluding property accessors

问题描述

假设我有以下程序:

namespace ReflectionTest
{
    public class Example
    {
        private string field;

        public void MethodOne() { }

        public void MethodTwo() { }

        public string Property
        {
            get { return field; }
            set { this.field = value; }
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            iterate(typeof(Example));

            Console.ReadLine();
        }

        public static void iterate(Type type)
        {
            MethodInfo[] methods = type.GetMethods(
                BindingFlags.DeclaredOnly |
                BindingFlags.Instance |
                BindingFlags.Public);

            foreach (MethodInfo mi in methods)
            {
                Console.WriteLine(mi.Name);
            }
        }
    }
}

运行程序时，我得到以下输出:

When I run the program I'm getting the following output:

MethodOne
MethodTwo
get_Property
set_Property

我想跳过属性accesor方法.我尝试使用其他 BindingFlags ，例如〜BindingFlags.SetProperty ，但没有运气.目前，我发现跳过这些方法的唯一方法是将迭代函数重写为:

I want to skip the property accesor methods. I've tried with different BindingFlags, for instance, ~BindingFlags.SetProperty, but with no luck. At the moment the only way I've found to skip those methods is rewriting the iterate function to:

public static void iterate(Type type)
{
    MethodInfo[] methods = type.GetMethods(
        BindingFlags.DeclaredOnly |
        BindingFlags.Instance |
        BindingFlags.Public);

    foreach (MethodInfo mi in methods)
    {
        if (mi.IsSpecialName) continue;
        Console.WriteLine(mi.Name);
    }
}

您知道我应该使用什么 BindingFlags 吗?

Do you know what BindingFlags should I use?

嗯，我应该已经解释说，该项目实际上是用于自动构建用于单元测试的模板，因此我可以跳过所有特殊方法.感谢您提供有关IsSpecialName的其他信息:)

Well, I should have explained that the project is actually for building automatically templates for unit testing, so I can skip all the special methods. Thanks for the additional information on IsSpecialName :)

LINQ?真的吗?哇.无论如何，该项目是.NET 2.0，因此(非常)不能选择LINQ.

LINQ? Really? Wow. Anyway, this project is .NET 2.0 so LINQ is (sadly) not an option.

推荐答案

从我的头顶开始:

mi.IsSpecialName &&( mi.Name.StartsWith("set_") || mi.Name.StartsWith("get_"))

应该让您一切就绪.SpecialName不仅仅是属性访问器(事件添加/删除方法在这里也算在内)，这就是为什么您还必须检查名称的原因.

should get you all set. SpecialName is more than property accessors (event add/remove methods count here as well), that's why you have to check the names as well.

您也可以使用LINQ:)

You can use LINQ for that as well :)
