这是目标文件。如何简化此代码?如何减少下面的字符串重复?
$(IntermediateOutputPath)$([System.Text.RegularExpressions.Regex]::Replace('%(ProtocCompile.RelativeDir)','\.\.[/\\]',''))
答案 0 :(得分:1)
因为你已经为这个值指定了一个属性,如下所示:
<PropertyGroup>
<protooutdir>$(IntermediateOutputPath)$([System.Text.RegularExpressions.Regex]::Replace('%(ProtocCompile.RelativeDir)','\.\.[/\\]',''))</protooutdir>
</PropertyGroup>
您可以使用属性 $(protooutdir)替换对该字符串的引用,如下所示:
<CreateItem Include="$(protooutdir)%(ProtocCompile.Filename).cs">
和
<Delete Files="$(protooutdir)%(ProtocCompile.Filename).cs" />
