多线程之泛型参数
有时候我们需要给线程传参，而.net的ParameterizedThreadStart不支持泛型，参数只能是object，使用起来有点小不爽的感觉。其实只要简单的包装一下Thread，就能在使用的时候心情舒畅了。
/// <summary> /// 泛型参数线程 /// </summary> /// <typeparam name="parameterType">参数类型</typeparam> public struct thread<parameterType> { /// <summary> /// 线程委托 /// </summary> private Action<parameterType> Handle; /// <summary> /// 线程参数 /// </summary> private parameterType Parameter; /// <summary> /// 初始化 泛型参数线程 /// </summary> /// <param name="handle">线程委托</param> /// <param name="parameter">线程参数</param> public thread(Action<parameterType> handle, parameterType parameter) { if (handle == null) new showjim.sys.debug("缺少 线程委托").throwException(); Handle = handle; Parameter = parameter; } /// <summary> /// 启动线程并返回线程句柄 /// </summary> /// <returns>线程句柄</returns> public Thread start() { Thread thread = new Thread(ParameterThread); thread.IsBackground = true; thread.Start(); return thread; } /// <summary> /// 调用线程委托 /// </summary> private void ParameterThread() { Handle(Parameter); } /// <summary> /// 启动线程并返回线程句柄 /// </summary> /// <param name="handle">线程委托</param> /// <param name="parameter">线程参数</param> /// <returns>线程句柄</returns> public static Thread start(Action<parameterType> handle, parameterType parameter) { return new thread<parameterType>(handle, parameter).start(); } }对于有返回值的线程调用，是否需要回调功能呢，索性一起搞定吧。
