问题描述
所以,this 和 this 非常清楚.只需传递 /p:DefineConstants="SYMBOL"
So, both this and this are pretty clear. Simply pass /p:DefineConstants="SYMBOL"
它对我来说根本不起作用,即使在测试项目中也是如此.我期望传递/p:DefineConstants="SYMBOL" 将覆盖 csproj 中定义的任何条件编译常量.然而事实并非如此......
It doesn't work at all for me, even in a test project. I'm expecting that passing /p:DefineConstants="SYMBOL" will override any conditional compilation constants defined in the csproj. Not the case however...
下面的完整代码清单:
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace DefineConstants { class Program { static void Main(string[] args) { #if DEV Console.WriteLine("DEV"); #elif UAT Console.WriteLine("UAT"); #else Console.WriteLine("No environment provided"); #endif } } }
.csproj 文件是:
.csproj file is:
<?xml version="1.0" encoding="utf-8"?> <Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration> <Platform Condition=" '$(Platform)' == '' ">x86</Platform> <ProductVersion>8.0.30703</ProductVersion> <SchemaVersion>2.0</SchemaVersion> <ProjectGuid>{57A2E870-0547-475C-B0EB-66CF9A2FE417}</ProjectGuid> <OutputType>Exe</OutputType> <AppDesignerFolder>Properties</AppDesignerFolder> <RootNamespace>DefineConstants</RootNamespace> <AssemblyName>DefineConstants</AssemblyName> <TargetFrameworkVersion>v3.5</TargetFrameworkVersion> <FileAlignment>512</FileAlignment> </PropertyGroup> <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x86' "> <PlatformTarget>x86</PlatformTarget> <DebugSymbols>true</DebugSymbols> <DebugType>full</DebugType> <Optimize>false</Optimize> <OutputPath>binDebug</OutputPath> <DefineConstants>TRACE;DEBUG</DefineConstants> <ErrorReport>prompt</ErrorReport> <WarningLevel>4</WarningLevel> </PropertyGroup> <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' "> <PlatformTarget>x86</PlatformTarget> <DebugType>pdbonly</DebugType> <Optimize>true</Optimize> <OutputPath>binRelease</OutputPath> <DefineConstants>TRACE</DefineConstants> <ErrorReport>prompt</ErrorReport> <WarningLevel>4</WarningLevel> </PropertyGroup> <ItemGroup> <Reference Include="System" /> <Reference Include="System.Core" /> <Reference Include="System.Xml.Linq" /> <Reference Include="System.Data.DataSetExtensions" /> <Reference Include="System.Data" /> <Reference Include="System.Xml" /> </ItemGroup> <ItemGroup> <Compile Include="Program.cs" /> <Compile Include="PropertiesAssemblyInfo.cs" /> </ItemGroup> <Import Project="$(MSBuildToolsPath)Microsoft.CSharp.targets" /> <!-- To modify your build process, add your task inside one of the targets below and uncomment it. Other similar extension points exist, see Microsoft.Common.targets. <Target Name="BeforeBuild"> </Target> <Target Name="AfterBuild"> </Target> --> </Project>
使用:
C:WindowsMicrosoft.NETFrameworkv4.0.30319msbuild DefineConstants.sln /p:DefineConstants="DEV;DEBUG" /p:Configuration="Debug" /p:Platform="x86"
运行程序显示:
No environment provided
帮助!
推荐答案
使用 DefineConstants 确实有效.这意味着你做错了什么.我的猜测是您首先构建了项目而没有定义任何内容,然后再次构建它.然后 MSBuild 将看到该项目已经构建并且不会再次构建,而只是复制输出文件.您应该发布 msbuild 的输出,以便我们确定,但作为参考,我只使用必要的开关编译了您的项目,结果如下(省略了完整的 msbuild 输出):
Using DefineConstants definitely does work. Which means you are doing something wrong. My guess is you first built the project without defining anything, then built it again. MSBuild will then see the project was built already and won't build again, but just copy output files. You should post the output of msbuild so we can be sure, but for reference I compiled your project using the necessary switches only and here is the result (full msbuild output omitted):
> msbuild ConsoleApplication1.sln /p:DefineConstants="DEV" /t:Rebuild .... Building solution configuration "Debug|x86". Project ... is building ConsoleApplication1.csproj" (Rebuild target(s)). ... > ConsoleApplication1inDebugDefineConstants.exe DEV > msbuild ConsoleApplication1.sln /p:DefineConstants="UAT" /t:Rebuild ... > ConsoleApplication1inDebugDefineConstants.exe UAT > msbuild ConsoleApplication1.sln /t:Rebuild ... > ConsoleApplication1inDebugDefineConstants.exe No environment provided
