Question

我正在使用此代码，我正在调用从dll动态加载的类列表的run方法：

for (int i = 0; i < robotList.Count; i++)
{
    Type t = robotList[i]; //robotList is a List<Type>
    object o = Activator.CreateInstance(t);
    t.InvokeMember("run", BindingFlags.Default | BindingFlags.InvokeMethod, null, o, null);
}

invokeMember正在调用列表中每个类的run方法。

现在如何在单独的主题中从run调用此invokeMember方法？这样我就可以为每个被调用的方法运行单独的线程。

Answer 1

如果您知道所有动态加载的类型都实现了Run，那么您是否只需要它们都实现IRunable并摆脱反射部分？

Type t = robotList[i];
IRunable o = Activator.CreateInstance(t) as IRunable;
if (o != null)
{
    o.Run(); //do this in another thread of course, see below
}

如果没有，这将有效：

for (int i = 0; i < robotList.Count; i++)
{
    Type t = robotList[i];
    object o = Activator.CreateInstance(t);
    Thread thread = new Thread(delegate()
    {
        t.InvokeMember("Run", BindingFlags.Default | BindingFlags.InvokeMethod, null, o, null);
    });
    thread.Start();
}

看一下这个样本的一种方法：

using System;
using System.Threading;
using System.Reflection;
using System.Collections.Generic;

namespace Obfuscation
{
    public class Program
    {
        static Type[] robotArray = new Type[] { typeof(Program) };
        static List<Type> robotList = new List<Type>(robotArray);

        internal void Run()
        {
            Console.WriteLine("Do stuff here");
        }

        internal static void RunInstance(object threadParam)
        {
            Type t = (Type)threadParam;
            object o = Activator.CreateInstance((Type)t);
            t.InvokeMember("Run", BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.NonPublic, null, o, null);
        }

        public static void Main(string[] args)
        {
            for (int i = 0; i < robotList.Count; i++)
            {
                ThreadPool.QueueUserWorkItem(new WaitCallback(RunInstance), robotList[i]);
            }
        }
    }
}

C＃：在单独的Thread中调用[Type] .InvokeMember（）方法
