Referencing DLLs ?

Hi ,

I have two dlls Company.dll and DataAccess.dll written in C#.

DataAccess.dll is referencing Company.dll.

Now I created a C# class library project in which I  added these two dlls as references.

But I am not able to access DataAccess.dll I can only use Company.dll.

Can someone help me out with this ?

Thanks,
Priya
