在另一个线程中运行函数的C＃泛型

Question

我有一些泛型函数在后台线程中运行方法。在正常的线程同步问题之外，这里是否存在任何危险？

public static void ThreadRunReturn<TReturn, TArgument>(Func<TArgument, TReturn> func, TArgument arg, bool background = true) 
    { 
     Thread th = new Thread(unused => func(arg)); 
     th.IsBackground = background; 
     th.Start(th); 
    } 
    public static void ThreadRunReturn<TReturn, TArgument1, TArgument2>(Func<TArgument1, TArgument2, TReturn> func, TArgument1 arg1, TArgument2 arg2, bool background = true) 
    { 
     Thread th = new Thread(unused => func(arg1, arg2)); 
     th.IsBackground = background; 
     th.Start(th); 
    } 

    public static void ThreadRun<TArgument>(Action<TArgument> action, TArgument arg, bool background = true) 
    { 
     Thread th = new Thread(unused => action(arg)); 
     th.IsBackground = background; 
     th.Start(th); 
    } 
    public static void ThreadRun<TArgument1, TArgument2>(Action<TArgument1, TArgument2> action, TArgument1 arg1, TArgument2 arg2, bool background = true) 
    { 
     Thread th = new Thread(unused => action(arg1, arg2)); 
     th.IsBackground = background; 
     th.Start(th); 
    }

后台线程不会使应用程序保持活动状态。如果你长时间运行后台进程并且你的应用程序终止，它不会等待这些后台线程完成 - 它会杀死它们。只是要记住。
