的MSBuild枢转的ItemGroup上分隔字符串

Question

我有安装的的ItemGroup，每一个包含这样的属性，它是从输出文件夹（分隔）的名称：

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

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

我希望能够复制每个安装程序放入指定的每个文件夹中。我已经来回试图找出一种方法来额外的元数据添加到安装程序，但似乎无法得到的是这样的一个最后的名单：

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

所以我可以执行这样的事情：

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

我知道我可以修改我的ItemGroup这样：

<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> 

，但我宁愿不要，因为这就是我们现在的人有总是想念事情（因为它非常冗长）。

用分号分隔的文件夹名称，然后反安装程序和文件夹的值：

<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> 

输出为现在的任务是：

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