C# : Invoke a method with [Type].InvokeMember() in a separate Thread
提问by Andreas Grech
I am using this code where I am invoking the runmethod of a List of classes that I loaded dynamically from dlls:
我正在使用此代码，在其中调用run我从 dll 动态加载的类列表的方法：
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);
}
The invokeMemberis invoking the runmethodof each of the classes in the list.
在invokeMember被调用run推法每一类在列表中。
Now how can I invoke this runmethod from invokeMemberin a separate Thread? So that I'll have separate threads running for each of the invoked methods.
现在如何run从invokeMember单独的 Thread调用此方法？这样我就会为每个调用的方法运行单独的线程。

If you know that all your dynamically loaded types implement Run, could you just require they all implement IRunable and get rid of the reflection part?
如果您知道所有动态加载的类型都实现了 Run，是否可以只要求它们都实现 IRunable 并去掉反射部分？
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
}
If not, this will work:
如果没有，这将起作用：
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();
}

Have a look at this sample for one way of doing it:
查看此示例以了解一种方法：
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]);
}
}
}
}
