C# WPF自定义消息弹窗

我用的是Caliburn Micro框架，自建框架或者使用其它框架的可自行替换绑定部分即可。

效果图：

 消息窗体View代码：

<Window x:Class="WpfAppTest.Views.MsgBoxView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                        </Border>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">

                        </ControlTemplate.Triggers>
                    </ControlTemplate>

            </Setter>
        </Style>
    </Window.Resources>
    <Grid>
        <Grid.RowDefinitions>

        <Button Grid.Row="2" Content="确定" Width="100" cm:Message.Attach="SureClick" Style="{StaticResource LongButtonStyle}"/>
    </Grid>
</Window>

消息窗体cs代码：

    public partial class MsgBoxView : Window
    {
        public MsgBoxView(MsgBoxViewModel viewModel)
        {
            InitializeComponent();
            this.DataContext = viewModel;
            viewModel.OnRequestClose += ViewModel_OnRequestClose;
        }

        private void ViewModel_OnRequestClose(object sender, EventArgs e)
        {
            this.Close();
        }
    }

消息窗体ViewModel代码：

    public class MsgBoxViewModel : PropertyChangedBase
    {
        private string _strTitle;
        public string StrTitle
        {
            get { return _strTitle; }
            set { Set(ref _strTitle, value, nameof(StrTitle)); }
        }

        private string _strMsg;
        public string StrMsg
        {
            get { return _strMsg; }
            set { Set(ref _strMsg, value, nameof(StrMsg)); }
        }

        public MsgBoxViewModel(string strTitle, string strMsg)
        {
            StrTitle = strTitle;
            StrMsg = strMsg;
        }
        public event EventHandler OnRequestClose;
        public void SureClick()
        {
            OnRequestClose?.Invoke(this, EventArgs.Empty);
        }
    }

调用弹窗：

            MsgBoxViewModel msgBoxViewModel = new MsgBoxViewModel("警告","纯属测试");
            MsgBoxView msgBoxView = new MsgBoxView(msgBoxViewModel);
            msgBoxView.ShowDialog();
