Question

是否可以创建我自己的自定义MessageBox，我可以在其中添加图像而不是仅添加字符串？

Answer 1

我也想要这个功能，所以我创建了WPFCustomMessageBox，一个原生Windows / .NET MessageBox的WPF克隆，它支持自定义按钮文本等额外功能。

WPFCustomMessageBox使用静态方法，就像标准.NET MessageBox一样，因此您可以即插即用新库，而无需修改任何代码。最重要的是，我设计了此控件，使其看起来与原始MessageBox 相同。

WPFCustomMessageBox example

我创建了这个库，因为我想将动词用于我的MessageBox按钮help users better understand the functionality of the buttons。使用此库，您可以为用户提供关键字说明，例如Save/Don't Save或Eject Fuel Rods/Don't do it!，而非标准OK/Cancel或Yes/No（如果您愿意，也可以使用它们））。

WPFCustomMessageBox消息框返回standard .NET MessageBoxResults。它还提供与原始MessageBox相同的功能，例如MessageBoxIcons和自定义消息框字幕。

WPFCustomMessageBox是开源的，因此您可以在此处获取代码或进行改进：https://github.com/evanwon/WPFCustomMessageBox

您可以通过NuGet将WPFCustomMessage添加到您的项目中：https://www.nuget.org/packages/WPFCustomMessageBox/

Answer 4

我已经通过标准WPF控件模板实现了完全可自定义的WPF MessageBox：

http://blogs.microsoft.co.il/blogs/arik/archive/2011/05/26/a-customizable-wpf-messagebox.aspx

功能

类WPFMessageBox具有与当前WPF MessageBox类完全相同的接口。

作为自定义控件实现，因此可通过标准WPF控件模板完全自定义。

有一个默认的控件模板，看起来像标准的MessageBox。

支持所有常见类型的消息框：错误，警告，问题和信息。

与打开标准MessageBox时的“哔”声相同。

按Escape按钮作为标准MessageBox时支持相同的行为。

提供与标准MessageBox相同的系统菜单，包括在消息框处于Yes-No模式时禁用“关闭”按钮。

处理右对齐和从右到左的操作系统，与标准MessageBox相同。

支持将所有者窗口设置为WinForms表单控件。

Answer 5

不确定。我通过继承System.Windows.Window并添加显示各种内容（图像，文本和控件）的容量，然后在该窗口上调用ShowDialog()来完成它：

public partial class MyMessageBox : Window
{
    // perhaps a helper method here
    public static bool? Show(String message, BitmapImage image)
    {
        // NOTE: Message and Image are fields created in the XAML markup
        MyMessageBox msgBox = new MyMessageBox() { Message.Text = message, Image.Source = image };
        return msgBox.ShowDialog();
    }
}

在XAML中，类似这样：

<Window>
    <DockPanel>
        <Image Name="Image" DockPanel.Dock="Left" />
        <TextBlock Name="Message" />
    </DockPanel>
</Window>
