Socket 简易静态服务器 WPF MVVM模式（三）

ViewModels类

这个类其实就是个大杂烩，什么都可以用

这个类没有什么东西，最多的就是写一下xaml页面的逻辑控制，开启关闭监听

                else
                    return false;
            }

        }

        private void  Exectue()
        {
            server.Start(IPadd,IPprot,10,FileUrl);
            run = false;
            input = false;
        }
    }
}

不过也有一点需要注意的 就是跨线程更新UI 这个地方MVVM报错的比较多
