How to write batch files correctly for publication Adding different precompiled macros during .NET programming?

Question

I have the following code:

#if PC
    var rootPath = Path.Combine("dist");
#else
    var rootPath = Path.Combine(@"/bin/bash");
#endif

I want to write different batch files when publishing the program to decide whether to add the macro "PC" or not.

But I didn't find the answer under the dotnet publish command.

Answer 1

1. Add a configuration (Pc) in your .csproj file, and add the PC symbol:

   <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Pc|AnyCPU'">
       <DefineConstants>$(DefineConstants);PC</DefineConstants>
   </PropertyGroup>
   

   Use -c option to pick this configuration:

   dotnet publish -c:Pc
   

2. Use msbuild's -getProperty and -p options to define the symbols:

   SET cmdGetProp='dotnet msbuild -getProperty:DefineConstants'
   FOR /F "tokens=*" %%s IN (%cmdGetProp%) DO SET prop=%%s
   dotnet publish -p:DefineConstants=\"%prop%;PC\"
