CompilerOptions.

Question

I am trying to use the C# CodeCom provider and in particular I find two options, one that specifies the "ReferencedAssemblies" and one that specifies the compiler options ("CompilerOptions"). If I specified the full path to some of the .NET 3.0 assemblies like:

cp.ReferencedAssemblies.Add("System.dll");

cp.ReferencedAssemblies.Add(@"C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0\System.ServiceModel.dll");

This works. If I don't specify the path then I get errors indicting ServiceModel.dll could not be found. Rather than specifying the full path to all of the .NET 3.0 assemblies I would like to let the compiler know where else it can search for assemlies. I have chosen:

cp.CompilerOptions = string.Format("/lib:{0}", @"C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0");

I still get erros that the assembly cannot be found and I look at some of the temporary files (specifically the .cmdline) file and I find that the /lib option is not there. It seems that the "CompilerOptions" are being ignored. Is there something I am missing so I can pick up an additional assembly search path?

Thank you.

Answer 1

Try adding an extra space before "/lib" (making it " /lib"), it is the last argument passed to the compiler but the framework adds a trailing space, not a leading space.  Also try referencing the assembly by its display name so the compiler finds it in the GAC.  For example: "System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089".

Answer 2

I tried adding the space and I still get:

  error CS0006: Metadata file 'System.ServiceModel.dll' could not be found
  error CS0006: Metadata file 'System.Runtime.Serialization.dll' could not be fo

I don't know the details of the .NET 3.0 assemblies (PublicKeyToken, etc.) at this time so I have not tried that yet. I still have:

cp.CompilerOptions = string.Format(" /lib:{0}", @"C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0");

cp.ReferencedAssemblies.Add("System.dll");

cp.ReferencedAssemblies.Add("System.ServiceModel.dll");

cp.ReferencedAssemblies.Add("System.Runtime.Serialization.dll");

Looking at the command line temporary file it looks like even with the space the CompilerOptions are getting ignored:

/t:library /utf8output /R:"System.dll" /R:"System.ServiceModel.dll" /R:"System.Runtime.Serialization.dll" /out:"wsDataContract.dll" /D:DEBUG /debug+ /optimize- /w:3 /optimize  "wsDataContract.cs"

Answer 4

If I have a third party dll that is GAC'ed, specifying it's full assembly name still generates a CS0006 exception. 

Answer 5

This works:

par.CompilerOptions = string.Format(@" /lib:{0}", "\"C:\\Program Files\\Reference Assemblies\\Microsoft\\Framework\\v3.0\"");

You'll have to enclose the path with double quotes "", because the options are commandline options. Without the double quotes the argument is splitted up in three parts:
c:\Program , Files\Reference and Assemblies\Microsoft\Framework\v3.0

Hope this is helps for anyone who is looking at this thread.

Worked for me, and within a sharepoint workflow no less.

Thanks!
