MessageBox

实现MessageBox的Show五种方法；
- Show(string messageBoxText) 传入Msg参数；
- Show(string messageBoxText, string caption) 传入Msg与标题参数；
- Show(string messageBoxText, string caption, MessageBoxButton button) 传入Msg与标题、操作按钮参数；
- Show(string messageBoxText, string caption, MessageBoxImage icon) 传入Msg与标题、消息图片参数；
- Show(string messageBoxText, string caption, MessageBoxButton button, MessageBoxImage icon) 传入Msg与标题、操作按钮、消息图片参数；
拿到父级Window窗体的内容Content,放入一个Grid里,再在容器里放入一个半透明的Grid，最后将整个Grid赋给父级Window窗体的内容Content；

一、MessageBox.cs 代码如下；

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Media;  namespace WPFDevelopers.Minimal.Controls {     public static class MessageBox     {         public static MessageBoxResult Show(string messageBoxText)         {             var msg = new WPFMessageBox(messageBoxText);             return GetWindow(msg);         }         public static MessageBoxResult Show(string messageBoxText, string caption)         {             var msg = new WPFMessageBox(messageBoxText, caption);             return GetWindow(msg);         }         public static MessageBoxResult Show(string messageBoxText, string caption, MessageBoxButton button)         {             var msg = new WPFMessageBox(messageBoxText, caption, button);             return GetWindow(msg);         }         public static MessageBoxResult Show(string messageBoxText, string caption, MessageBoxImage icon)         {             var msg = new WPFMessageBox(messageBoxText, caption, icon);             return GetWindow(msg);         }         public static MessageBoxResult Show(string messageBoxText, string caption, MessageBoxButton button, MessageBoxImage icon)         {             var msg = new WPFMessageBox(messageBoxText, caption,button,icon);             return GetWindow(msg);         }          static MessageBoxResult GetWindow(WPFMessageBox msg)         {             msg.WindowStartupLocation = WindowStartupLocation.CenterOwner;             Window win = null;             if (Application.Current.Windows.Count > 0)                 win = Application.Current.Windows.OfType<Window>().FirstOrDefault(o => o.IsActive);             if (win != null)             {                 var layer = new Grid() { Background = new SolidColorBrush(Color.FromArgb(128, 0, 0, 0)) };                 UIElement original = win.Content as UIElement;                 win.Content = null;                 var container = new Grid();                 container.Children.Add(original);                 container.Children.Add(layer);                 win.Content = container;                 msg.Owner = win;                 msg.ShowDialog();                 container.Children.Clear();                 win.Content = original;             }             else                 msg.Show();             return msg.Result;         }     } }

二、Styles.MessageBox.xaml 代码如下；

三、WPFMessageBox.cs 代码如下；
