WPF - 全局添加xaml名称空间声明

Question

我有一个很大的WPF应用程序,有很多XAML文件.每个XAML文件都有5到10个clr到xml命名空间映射xmlns:abc="clr-namespace:Abcdef".
它看起来很糟糕,并且在每个文件中写入都很痛苦.

有没有办法在全球范围内定义？

Answer 1

无法跨文件全局定义它们.这是XML的限制; XAML是它的一个子集.

但是你可以用它来清理它们 XmlnsDefinition

请参阅此文章:http://zachbonham.blogspot.com/2010/04/organize-xaml-namespace-declarations.html

如果您从这个XAML开始:

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:treeView="clr-namespace:MaryKay.SamPortal.Common.UI.TreeView.Views;assembly=MaryKay.SamPortal.Common.UI"
    xmlns:infoBar="clr-namespace:MaryKay.SamPortal.Common.UI.InfoBar.Views;assembly=MaryKay.SamPortal.Common.UI">
  <infoBar:InformationBar DataContext="{Binding InfoBar}"/>
</UserControl>

并添加了以下XmlnsDefinition属性:

[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.InfoBar.Views")]
[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.RoleGroupPicker.Views")]
[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.BetterPopup")]
[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.TextEditor")]
[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.Converters")]
[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.Documents")]
[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.SplashScreen")]
[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.TemplateSelector")]
[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.ModalDialog")]
[assembly: XmlnsDefinition("urn:marykay-samportal-common-ui", "MaryKay.SamPortal.Common.UI.ConsultantSearch.Views")]
// etc...

您最终可能会使用此XAML:

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:commonUI="urn:marykay-samportal-common-ui">
  <commonUI:InformationBar DataContext="{Binding InfoBar}"/>
</UserControl>
