Using the VIPS DLL

Question

I have just started learning C# and ASP.NET for my project and i need to use the VIPS(VIsion based Page Segmentation) DLL but i don't know how to go about doing that as im new to C# and ASP.NET.I know how to create and use a simple DLL using C# but then i want to know how to find out the names of the classes and/or functions inside the VIPS DLL and how to use it.I have tried 2 or 3 DLL viewers and disassemblers but the output they gave is in asm format which is very hard to read and understand.
