Question

I have an application that invokes my DLL with InvokeMember() like so:

Assembly OCA = Assembly.LoadFrom("./Modules/ProcessFiles.dll");
Type[] types = OCA.GetTypes();
foreach (var type in types)
{
    //MethodInfo[] methods = type.GetMethods();
    if (type.Name == "Converter")
    {
        var tmpType = type;
        var obj = Activator.CreateInstance(tmpType);
        Thread t = new Thread(
            () =>
            tmpType.InvokeMember("Run", BindingFlags.Default | BindingFlags.InvokeMethod, null, obj,
            null));
        t.Start();
        break;
    }

}

My DLL then creates new a thread and starts processing. In my DLL, I the create new thread like this:

Thread thread = new Thread(
    delegate(){
        while(true)
        {
            GetFilesInFolder();
            Thread.Sleep(120000);
        }
    });
ne.Start();

The goal is to periodically check the folder. The problem is that when I close the application that invokes my DLL, the process is not closed. Is there a way to close all the threads?

NB: I can’t modify the application, I can only modify my DLL.

Answer 1

Set the IsBackground property of the thread to true. This will kill the thread when your app finishes.

Also: Why don’t you use one timer (or just one thread), that wakes and eximines the data. That should be more resource friendly.
