<Target Name="ProtobufCompile"
        Inputs="@(ProtocCompile)"
        Outputs="$(IntermediateOutputPath)$([System.Text.RegularExpressions.Regex]::Replace( %(ProtocCompile.RelativeDir) , ..[/\] ,  ))%(ProtocCompile.Filename).cs">
  <PropertyGroup>
    <protooutdir>$(IntermediateOutputPath)$([System.Text.RegularExpressions.Regex]::Replace( %(ProtocCompile.RelativeDir) , ..[/\] ,  ))</protooutdir>
  </PropertyGroup>
  <Message Text="%(ProtocCompile.Filename)%(ProtocCompile.Extension)" Importance="high" />
  <MakeDir Directories="$(protooutdir)" />

<Target Name="ProtobufCSharpCompile"
        DependsOnTargets="ProtobufCompile">
  <CreateItem Include="$(IntermediateOutputPath)$([System.Text.RegularExpressions.Regex]::Replace( %(ProtocCompile.RelativeDir) , ..[/\] ,  ))%(ProtocCompile.Filename).cs">

这是一份目标文件。如何简化这一法典? • 如何减少下文描述的重复?

$(IntermediateOutputPath)$([System.Text.RegularExpressions.Regex]::Replace( %(ProtocCompile.RelativeDir) , ..[/\] ,  ))

Answer 1

既然你已经指明了具有这种价值的财产:

  <PropertyGroup>
  <protooutdir>$(IntermediateOutputPath)$([System.Text.RegularExpressions.Regex]::Replace( %(ProtocCompile.RelativeDir) , ..[/\] ,  ))</protooutdir>
  </PropertyGroup>

您只能用$(protooutdir)等代替提及该雕刻的内容:

<CreateItem Include="$(protooutdir)%(ProtocCompile.Filename).cs">

以及

<Delete Files="$(protooutdir)%(ProtocCompile.Filename).cs" />
