編輯中的csproj文件

Question

的DefineConstants我有以下標籤的csproj：

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' "> 
    <DebugSymbols>true</DebugSymbols> 
    <DebugType>full</DebugType> 
    <Optimize>false</Optimize> 
    <OutputPath>Bin\Debug</OutputPath> 
    <DefineConstants>TRACE;DEBUG;SILVERLIGHT;WINDOWS_PHONE;SUPPORTS_ICLOUD</DefineConstants> 
    <NoStdLib>true</NoStdLib> 
    <NoConfig>true</NoConfig> 
    <ErrorReport>prompt</ErrorReport> 
    <WarningLevel>4</WarningLevel> 
    </PropertyGroup> 

在這裏，如果你看到我添加了一個名爲SUPPORTS_ICLOUD宏。

我有.txt文件中，我有以下幾點：

#define SUPPORTS_IN_APP_PURCHASE 

#define BUTTON_THEME  
#define SUPPORTS_TITLE 

#define HAS_HTML_IMAGE_CONTENT 
#define TINT_COLOR 
#define NAVIGATIONTITLE_TEXT_COLOR 

#define SUPPORTS_ICLOUD 

正如你可以在我的文本文件中看到我有很多的宏定義，現在不是在DefineConstants passsing每個宏可我乾脆把它傳遞作爲一個文件或一個字符串，以便它將採取所有這些？這是可能的還是有其他方法？

在我MainPage.cs文件;

#if SUPPORTS_ICLOUD 
      AppName.Text = "ABCD"; 
      Debug.WriteLine("App type is app with main screen"); 

#endif

您可以使用ReadLinesFromFile，該CreateProperty和item.Replace功能通過使用batching能力MSBuild引擎的更新您的財產：

<!-- property defintion --> 
    <PropertyGroup> 
    <MacroFile>def.txt</MacroFile> <!-- the filename with your #defines --> 
    </PropertyGroup> 

    <!-- other stuff in your build file --> 

    <!-- import common targets near the end of your build file --> 
    <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> 

    <!-- override targets (make sure this is AFTER the import elements) --> 
    <!-- BeforeBuild is pre-dfined target which can be overriden --> 
    <Target Name="BeforeBuild"> 
     <!-- Open the #define file and read every line in items named 
      MacrosFromFile 
     --> 
     <ReadLinesFromFile 
      File="$(MacroFile)" > 
      <Output 
       TaskParameter="Lines" 
       ItemName="MacrosFromFile"/> 
     </ReadLinesFromFile> 

     <!-- Create a new property called FileDefineConstants combining 
      every Item from MacrosFromFile 
      using the built-in replace statement to get 
      rid of the #define instruction 
     --> 
     <CreateProperty 
      Value="@(MacrosFromFile->Replace('#define ', ''))"> 
      <Output 
       TaskParameter="Value" 
       PropertyName="FileDefineConstants" /> 
     </CreateProperty> 

     <!-- re-create the orignal DefineConstants combining the current value 
      and the value from FileDefineConstants --> 
     <CreateProperty 
      Value="$(DefineConstants);$(FileDefineConstants)"> 
      <Output 
       TaskParameter="Value" 
       PropertyName="DefineConstants" /> 
     </CreateProperty> 

     <Message Text="Const >> $(DefineConstants)" /> 
    </Target>
