一次删除整个项目或解决方案中未使用的命名空间 [英] Remove unused namespaces across a whole project or solution at once

问题描述

我知道你可以逐个文件地做.

I know you can do it file by file.

是否有任何方法可以一步完成项目中的所有文件?

Is there any way to do this in one step for all files in a project?

推荐答案

你的意思是使用语句吗?首先，请注意，它们通常不会伤害其他占用空间的东西.ReSharper 等工具提供了自动执行此操作的技巧，但是:有一个 链接到VS提要一会儿前;归结为:

Do you mean using statements? First, note that they generally do no harm other that take space. Tools like ReSharper offer automated tricks to do this, however: there was a link in the VS feed a little while ago; it boils down to:

• 转到工具 -> 宏 -> 宏 IDE...
• 在 Project Explorer 中，添加 -> 添加模块...(输入名称 - 我使用了 OrganiseUsings)
• 粘贴下面的代码
• 文件 -> 保存 MyMacros，退出

现在，如果您右键单击工具栏并自定义... - 您应该能够找到 MyMacros.OrganiseUsings.RemoveAndSortAll - 将其拖到方便的地方(可能是工具菜单；您可能还想在放置后更改名称它).

Now if you right-click on the toolbar and Customize... - you should be able to find MyMacros.OrganiseUsings.RemoveAndSortAll - drag this somewhere handy (maybe the Tools menu; you might also want to change the name after placing it).

您现在可以使用此选项为整个解决方案运行删除和排序命令.大大节省时间.

You can now use this option to run the Remove and Sort command for an entire solution. A big time-saver.

                window.Activate()
