You can use PInvoke

Platform Invocation Services (PInvoke) allows managed code to call unmanaged functions that are implemented in a DLL.

Here is a great tutorial by the NAG (Numerical Algorithms Group) group

You can do a DllImport in your C# code and then use PInvoke.

For your custom dll you can try this example answer on SO.

This a good website for reference for using windows dlls
