的MSBuild樞轉的ItemGroup上分隔字符串

Question

我有安裝的的ItemGroup，每一個包含這樣的屬性，它是從輸出文件夾（分隔）的名稱：

<ItemGroup> 
    <Installers Include="Installer1.msi"> 
    <Folders>Folder1,Folder4</Folders> 
    </Installers> 

    <Installers Include="Installer2.msi"> 
    <Folders>Folder1,Folder2,Folder3,Folder4</Folders> 
    </Installers> 
</ItemGroup> 

我希望能夠複製每個安裝程序放入指定的每個文件夾中。我已經來回試圖找出一種方法來額外的元數據添加到安裝程序，但似乎無法得到的是這樣的一個最後的名單：

1. Installer1.msi：Folder1中
2. Installer1.msi：Folder4
3. Installer2.msi：Folder1中
4. Installer2.msi：文件夾2
5. Installer2.msi：Folder3
6. Installer2.msi：Folder4

所以我可以執行這樣的事情：

<Copy SourceFiles="@(Installers)" DestinationFolder="%(Installers.Folder)" /> 

我知道我可以修改我的ItemGroup這樣：

<ItemGroup> 
    <Installers Include="Installer1.msi"> 
    <Folder>Folder1</Folder> 
    </Installers> 
    <Installers Include="Installer1.msi"> 
    <Folder>Folder4</Folder> 
    </Installers> 

    <Installers Include="Installer2.msi"> 
    <Folder>Folder1</Folder> 
    </Installers> 
    <Installers Include="Installer2.msi"> 
    <Folder>Folder2</Folder> 
    </Installers> 
    <Installers Include="Installer2.msi"> 
    <Folder>Folder3</Folder> 
    </Installers> 
    <Installers Include="Installer2.msi"> 
    <Folder>Folder4</Folder> 
    </Installers> 
</ItemGroup> 

，但我寧願不要，因爲這就是我們現在的人有總是想念事情（因爲它非常冗長）。

Answer 1

用分號分隔的文件夾名稱，然後反安裝程序和文件夾的值：

<Project ToolsVersion="4.0" DefaultTargets="Inversionator" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> 
    <ItemGroup> 
     <Folders Include="Folder1;Folder4"> 
      <Installer>Installer1.msi</Installer> 
     </Folders> 
     <Folders Include="Folder1;Folder2;Folder3;Folder4"> 
      <Installer>Installer2.msi</Installer> 
     </Folders> 
    </ItemGroup> 

    <Target Name="Inversionator"> 
     <Message Text="%(Folders.Installer) %(Folders.Identity) " Importance="high" /> 
    </Target> 
</Project> 

輸出爲現在的任務是：

Installer1.msi Folder1 
Installer1.msi Folder4 
Installer2.msi Folder1 
Installer2.msi Folder2 
Installer2.msi Folder3 
Installer2.msi Folder4
