| Are you familiar with .NET Interops? Have a read up on these and see if this will solve you problem. I have used other language libraries in C# by building an interop for them. Then they can be imported and used just like any other component. | |||

| Hi Zaita, Can U send sample code which U had tried so that I can get idea about using Interop? Thanks in advance Atul | |||

| No. Interop is just a wrapper .NET puts around a non-.NET DLL so you can use it in .NET development. | |||
