找不到System.Windows.Media命名空间? [英] Can't find System.Windows.Media namespace?

问题描述

我正在使用来自第三方API的对象，该对象的属性类型为System.Windows.Media.ImageSource，但是我似乎在任何地方都找不到System.Windows.Media命名空间.如果我尝试添加对项目的引用，那么选项列表中不会显示System.Windows.Media.我的项目也针对.Net 3.5.

要访问该名称空间，我还需要做其他事情吗?

System.Windows.Media.Imaging名称空间是PresentationCore.dll的一部分(如果使用的是Visual Studio 2008，则WPF应用程序模板将自动添加此引用).请注意，此名称空间不是WIC库的直接包装，尽管仍然有很多更常用的用法，并且这些名称如何映射到WIC版本是相对明显的.有关此命名空间中的类的更多信息，请查看

I'm using an object from a 3rd party API that has a property of type System.Windows.Media.ImageSource, yet I can't seem to find the System.Windows.Media namespace anywhere. If I try to add a reference to my project I don't see System.Windows.Media in the list of options. My project is also targeting .Net 3.5.

Is there something else I need to do to be able to access this namespace?

解决方案

The System.Windows.Media.Imaging namespace is part of PresentationCore.dll (if you are using Visual Studio 2008 then the WPF application template will automatically add this reference). Note that this namespace is not a direct wrapping of the WIC library, although a large proportion of the more common uses are still available and it is relatively obvious how these map to the WIC versions.
