问题描述
我想创建一个任意字符串/名称的"ItemGroup",以便使用MSBuild转换,例如:
I want to create an "ItemGroup" of arbitrary strings / names in order to use MSBuild transforms, for example:
<ItemGroup>
<Categories>First</Categories>
<Categories>Second</Categories>
</ItemGroup>
然后我希望将这些类别的转换传递到控制台应用程序中,例如:
I then wish to pass a transform of these categories into a console app, e.g.:
/c @(Categories, ' /c ')
我在引号中说"ItemGroup"的原因是因为我不确定以这种方式使用ItemGroups是否适用于我-就我在文档中看不到的任何内容而言,ItemGroups 必须是文件,但是由于缺少必需的包含"属性,使用上述方法会导致错误消息.
The reason why I say "ItemGroup" in quotes, is because I'm not sure whether or not it is applicable for me to use ItemGroups in this way - as far as I can see nothing in the documentation states that ItemGroups must be files, however using the above results in an error message due to missing mandatory "Include" attribute.
- 是否可以使用ItemGroups完成上述操作?
- 或者,在不使用ItemGroups的情况下,还有一种更好的方法来实现上述目标吗?
推荐答案
您可以使用任意字符串以及Item
中的文件,但是必须使用以下语法:
You can use arbitrary string as well as files in Item
, but you must use this syntax :
<ItemGroup>
<Categories Include="First"/>
<Categories Include="Second"/>
</ItemGroup>
将Item
与任意字符串一起使用时,唯一的区别是某些元数据将毫无意义. (例如%(Categories.FullPath)
)
The only difference when you use Item
with arbitrary string is that some metadata will be meaningless. (%(Categories.FullPath)
for example)
然后,您可以使用Item来执行如下命令:
You can then use your Item to execute a command like this :
<Target Name="ExecCommand">
<Exec Command="YourProgram.exe /c @(Categories, ' /c ')"/>
<!-- Using transformation -->
<Exec Command="YourProgram.exe @(Categories -> '/c %(Identity)')"/>
</Target>
