从System.windows.FormsMessageBox转换为Xceed.Wpf.Toolkit.MessageBox时如何处理system.InvalidOperationException

Question

我有一个非常平淡的消息框，向我的用户询问一个简单的问题（不是或不是）。为了进行快速开发，我使用了一个简单的System.Windows.Forms.MessageBox并用词表达了问题（“如果要选择'A'，请单击'是'，如果要选择'B'，请单击'否'”）。现在，我要回过头来改善wpf应用程序的外观，并坚持尝试将此MessageBox转换为看起来不错的东西。

我的初步搜索告诉我使用Xceed.Wpf.Toolkit.MessageBox能够创建自定义消息框，但是在尝试使用它时出现了异常。

旧代码

DialogResult dialogResultForDataDisplay = System.Windows.Forms.MessageBox.Show("Yes: Display by properties \n \t Each row will contain data for a specific asset class in a specific submarket during a specific quarter. \n \n No: Display by quarters \n \t Each row will will show the change over time for a specific property of an asset class in a specific submarket.", "Data Grouping Format", MessageBoxButtons.YesNo);

新代码

Style style = new Style();
style.Setters.Add(new Setter(Xceed.Wpf.Toolkit.MessageBox.YesButtonContentProperty, "By Property"));
style.Setters.Add(new Setter(Xceed.Wpf.Toolkit.MessageBox.NoButtonContentProperty, "By Quarter"));
MessageBoxResult result = Xceed.Wpf.Toolkit.MessageBox.Show("How do you want your information displayed?", "My caption", MessageBoxButton.YesNo, MessageBoxImage.Warning, MessageBoxResult.Yes, style);
        Console.WriteLine(result);

新代码正在生成此异常：System.InvalidOperationException: 'The calling thread must be STA, because many UI components require this.'

您将如何处理此异常？

Answer 1

MessageBoxResult result = MessageBoxResult.None;
System.Windows.Application.Current.Dispatcher.Invoke((Action)delegate
{
    Style style = new Style();
    style.Setters.Add(new Setter(Xceed.Wpf.Toolkit.MessageBox.YesButtonContentProperty, "Yes, FTW!"));
    style.Setters.Add(new Setter(Xceed.Wpf.Toolkit.MessageBox.NoButtonContentProperty, "Omg, no"));
    result = Xceed.Wpf.Toolkit.MessageBox.Show("How do you want your information displayed?", "My caption", MessageBoxButton.YesNo, MessageBoxImage.Warning, MessageBoxResult.Yes, style);
}
Console.WriteLine(result);
