如果ItemGroup包含项目，如何进行MSBuild条件测试? [英] How do I do a MSBuild Condition testing if an ItemGroup contains an item?

问题描述

这应该很简单，但是我找不到执行该操作的方法(或者也许是不可能的.)

This should be simple, but I can't find how to do this (or maybe it's not possible).

在MSBuild中，我有一个ItemGroup，它是文件列表. 我只想在该ItemGroup中有特定文件的情况下执行任务

In MSBuild I have an ItemGroup that is a list of files. I want to execute a task only if a particular file is in that ItemGroup

类似的东西:

<Copy Condition="@(Files) <contains> C:\MyFile.txt" .... />

有什么办法吗?最好不要编写自定义任务.

Any way to do this? Preferably without writing a custom task.

文件列表仅与条件有关.否则，它与任务无关.

The list of files is only to do with the condition. Otherwise it has no relation to the task.

推荐答案

尝试

<Copy Condition="'%(Files.Identity)' == 'C:\MyFile.txt'" .. />
