[SOLVED] Removing a trailing slash in MSBuild / Convention based filename generation

Removing a trailing slash in MSBuild / Convention based filename generation

I'm trying to search for a set of assemblies based on the following convention within a directory:

{SubDirName}\{SubDirName}.dll

I've started by creating an MSBuild ItemGroup [by batching another ItemGroup on the .RecursiveDir portion].

<AllAssemblies Include="$(SourceDirectory)\**\Test.*.dll" />
<Dirs Include="@(AllAssemblies->'%(RecursiveDir)')"/>

Each item has a trailing slash, i.e.:

<Message Text="@(Dirs)"/>

Says:

SubDir1\;SubDir2\;SubDir3\

Now, I want to generate a set of filenames from this list.

The problem is that:

<AssembliesByConvention Include="@(Dirs -> '%(Identity)\%(Identity).dll')" />

Generates:

SubDir1\\SubDir1\.dll;SubDir2\\SubDir2\.dll;SubDir3\\SubDir3\.dll

I dont want the slashes before the period in .dll.

What's the cleanest way to achieve this?

I know there's a HasTrailingSlash expression operator, but there's no sign of a RemoveTrailingSlash task in the OOTB Tasks?. I'm not fussy about the MSBuild version required.

Solution

You can use MSBuild's .NET methods support in .NET 4.0 to replace the "\."s with "."s in the final result.

(This would at least solve my original problem)
