如何将物品拼合成物业？

根据这MSDN page (section Conversions between Strings and Item Lists)，它只是一个声明属性与物品作为价值的问题。

但我发现实际做法完全相反。当我运行这个项目的MSBuild 4.0，指定目标install ...

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> 
    <Import Project="$(Project-to-import)" Condition="'$(Project-to-import)' != ''" /> 

    <ItemGroup> 
    <RuntimeProj Include="C:\TEMP\Design.proj" /> 
    <DesigntimeProj Include="C:\TEMP\Run.dproj" /> 
    </ItemGroup> 

    <PropertyGroup> <!-- Flatten out the items to properties. --> 
    <RuntimeProj>@(RuntimeProj)</RuntimeProj> 
    <!--^This bit doesn't work. MS documentation is wrong? --> 
    <DesigntimeProj>@(RuntimeProj)</DesigntimeProj> 
    </PropertyGroup> 

    <Target Name="install"> 
    <Message Text="Hello world!"/> 
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="BuildRunPackage" 
      Properties="Project-to-import=$(RuntimeProj)" /> 
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="BuildDesignPackage" 
      Properties="Project-to-import=$(DesigntimeProj)" /> 
    </Target> 

    <Target Name="BuildRunPackage"> 
    <CallTarget Targets="Clean" /> 
    <CallTarget Targets="Build" /> 
    </Target> 

    <Target Name="BuildDesignPackage"> 
    <CallTarget Targets="Clean" /> 
    <CallTarget Targets="Make" /> 
    <CallTarget Targets="Register" /> 
    </Target> 
<.Project>

...返回一个错误......

错误MSB4012：表达式“项目，TO-进口= @（RuntimeProj）不能在这种情况下使用。项目列表不能与其中一个项目列表，预计其他字符串并置。使用分号来分隔多个项目清单。

我不是很确定，但我认为你会陷入评估订单问题。据我知道属性评估之前项目（请参阅http://msdn.microsoft.com/en-us/library/dd997067.aspx中的属性和项目评估顺序）如果您可以尝试从安装目标下的“全局”移动属性组。它应该工作。

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> 
    <Import Project="$(Project-to-import)" Condition="'$(Project-to-import)' != ''" /> 

    <ItemGroup> 
    <RuntimeProj Include="C:\TEMP\Design.proj" /> 
    <DesigntimeProj Include="C:\TEMP\Run.dproj" /> 
    </ItemGroup> 


    <Target Name="install"> 
    <PropertyGroup> <!-- Flatten out the items to properties. --> 
     <RuntimeProj>@(RuntimeProj)</RuntimeProj> 
     <DesigntimeProj>@(RuntimeProj)</DesigntimeProj> 
    </PropertyGroup> 

    <Message Text="Hello world!"/> 
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="BuildRunPackage" 
      Properties="Project-to-import=$(RuntimeProj)" /> 
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="BuildDesignPackage" 
      Properties="Project-to-import=$(DesigntimeProj)" /> 
    </Target> 

    <Target Name="BuildRunPackage"> 
    <CallTarget Targets="Clean" /> 
    <CallTarget Targets="Build" /> 
    </Target> 

    <Target Name="BuildDesignPackage"> 
    <CallTarget Targets="Clean" /> 
    <CallTarget Targets="Make" /> 
    <CallTarget Targets="Register" /> 
    </Target> 
</Project>

是的。这是做到这一点的方法。你必须在''中平整属性。 –
