我有一个定义了 Style 的 ResourceDictionary，它有一个带有绑定 StringFormat 的 ControlTemplate，如下所示：

<TextBlock Text="{Binding TotalCash, Mode=OneWay, StringFormat={}{0:N2}, FallbackValue=0.00}" />

我在本地运行，一切都很好，但是我在服务器上进行构建和安装，当我启动任何使用 ResourceDictionary 的 WFP 屏幕时，我得到以下异常：

System.Windows.Markup.XamlParseException: 'Unexpected token after end of markup extension.' Line number '224' and line position '148'. ---> System.Xaml.XamlParseException: 'Unexpected token after end of markup extension.' Line number '224' and line position '148'.

我做了一些挖掘并通过将 ResourceDictionary StringFormat 从 {}{0:N2} 更改为 N2 来使其工作：

<TextBlock Text="{Binding TotalCash, Mode=OneWay, StringFormat=N2, FallbackValue=0.00}" />

以下作品放入用户控件中：

<TextBlock Text="{Binding TotalCash, Mode=OneWay, StringFormat={}{0:N2}, FallbackValue=0.00}" />

我的问题是为什么相同的 StringFormat 在 UserControl 中起作用，但在 ResourceDictionary 中不起作用？我很高兴它正在工作，但想了解原因。

这是一个WPF 错误。

我猜你的开发机器上本地安装了 .NET 4.5（可能是因为安装了 Visual Studio 2012），但你的服务器上没有（只有 .NET 4）。因此，您的服务器没有 Microsoft 在 .NET 4.5 中添加到 WPF 的错误修复。
