[英]The type or namespace name 'Window' does not exist in the namespace 'System.Windows'
I am trying to write an extension method for the WPF Window class.我正在尝试为 WPF Window 类编写扩展方法。 I am doing it in a class library project in my solution, so that I can use it in all my projects in the solution.
我在我的解决方案中的类库项目中执行此操作,以便我可以在解决方案中的所有项目中使用它。
Here is my code:这是我的代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
namespace ExtensionMethods
{
public static class MyExtensions
{
public static void ResizeToPrimaryScreenWorkingArea(this System.Windows.Window w)
{
}
}
}
When I try to compile this, I get the following error:当我尝试编译它时,出现以下错误:
The type or namespace name 'Window' does not exist in the namespace 'System.Windows'
命名空间“System.Windows”中不存在类型或命名空间名称“Window”
Yes, I DID add references to System.Windows and System.Windows.Forms in my class library project, and they are showing under References in the project in Solution Explorer.是的,我确实在我的类库项目中添加了对 System.Windows 和 System.Windows.Forms 的引用,它们显示在解决方案资源管理器中项目中的引用下。
What am I doing wrong?我究竟做错了什么?
Add PresentationFramework.dll
reference to your project it contains the System.Windows
namespace.向包含
System.Windows
命名空间的项目添加PresentationFramework.dll
引用。
