所以,thisthis很清楚。只需传递 /p:DefineConstants="SYMBOL"

它对我根本不起作用,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......

完整代码如下:

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:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>

<OutputPath>bin\Release\</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="Properties\AssemblyInfo.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>

构建使用:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild DefineConstants.sln /p:DefineConstants="DEV;DEBUG" /p:Configuration="Debug" /p:Platform="x86"

运行程序显示:

No environment provided

求助!

最佳答案

使用 DefineConstants 绝对有效。这意味着你做错了什么。我的猜测是您首先在没有定义任何内容的情况下构建项目,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,但作为引用,我仅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):

> msbuild ConsoleApplication1.sln /p:DefineConstants="DEV" /t:Rebuild
....
Building solution configuration "Debug|x86".
Project ... is building ConsoleApplication1.csproj" (Rebuild target(s)).
...
> ConsoleApplication1\bin\Debug\DefineConstants.exe
DEV
> msbuild ConsoleApplication1.sln /p:DefineConstants="UAT" /t:Rebuild
...
> ConsoleApplication1\bin\Debug\DefineConstants.exe
UAT
> msbuild ConsoleApplication1.sln /t:Rebuild
...
> ConsoleApplication1\bin\Debug\DefineConstants.exe
No environment provided
