问题
Visual Studio 2013.
I have an external DLL which I am referencing like this in the csproj file:
<ItemGroup>
<Reference Include="NameOfDll">
<HintPath>Path\To\Dll\NameOfDll.dll</HintPath>
</Reference>
I want this reference to function when a compiler symbol exists and to not function when that compiler symbol does not exist. (To address the first comment, below, let's say the compiler symbol is called Fred.)
This question [ Conditional Reference ] made me think I could add an attribute called Condition to the Reference element shown above but I can't work out what value to give that attribute to effect what I want.
I'd be most happy to be given a way to do this in the VS UI but I'll take any method.
回答1:
The conditional compilation symbols are in the DefineConstants
MSBuild property. Check that this contains your symbol:
<Reference Include="NameOfDll" Condition="$(DefineConstants.Contains('Fred'))">
<HintPath>Path\To\Dll\NameOfDll.dll</HintPath>
</Reference>
Pick a distinctive name for the symbol. Not something that could be a substring of another constant like Debug or Trace.
