在另一個線程中運行函數的C＃泛型

Question

我有一些泛型函數在後臺線程中運行方法。在正常的線程同步問題之外，這裏是否存在任何危險？

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); 
    }

後臺線程不會使應用程序保持活動狀態。如果你長時間運行後臺進程並且你的應用程序終止，它不會等待這些後臺線程完成 - 它會殺死它們。只是要記住。
