It is not clear what you are asking but it sounds like you are asking us why your projects have dlls written in C instead of C#?

Because C# is nearly completely a Managed environment - if you want access to unmanaged memory, or to interface with the OS (which is unmanaged) then you generally have to use unmanaged code. C++ is the normal choice.

In addition, if you have C or C++ code that works perfectly well, why risk introducing bugs by translating it, if you can use it as-is directly from C#?

There can also be some performance gains by using C++ instead of C# for some things, but it's smaller than you might think for most code, and frequently swamped by the development time.
