怎么实现选中listview中一列控制按钮可用不可用？谢谢

Question

   private void listViewServices_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            //获取服务的运行状态
            ServiceController[] MyServices = ServiceController.GetServices();
            //将服务的名称添加到ListBox中
            for (int i = 0; i < MyServices.Length; i++)
            {
                string state = MyServices[i].Status.ToString();
                switch (state)
                {
                    case "Stopped":
                        lblState.Content = "服务已停止";
                        btnRestart.IsEnabled = false;
                        btnStart.IsEnabled = true;
                        btnStop.IsEnabled = false;
                        continue;
                    case "Running":
                        lblState.Content = "服务运行中";
                        btnStart.IsEnabled = false;
                        btnStop.IsEnabled = true;
                        btnRestart.IsEnabled = true;
                        continue;
                    case "StartPending":
                        lblState.Content = "服务正在启动";
                        continue;
                    case "StopPending":
                        lblState.Content = "服务正在停止";
                        continue;                }            }
这是控制windows服务启动停止的判断，现在是一运行选中列后就直接运行到case "Running": 再点击其他的列也不改变，哪里有问题啊，谢谢

不管Selection如何changed，你的执行代码都是一模一样的，当然不会有变化咯
