How to make connection to a database using an existing odbc connection in 64 bit platform

Hi,

I have configured an ODBC connection to a SQL Server database using odbcad32 from SysWow64 folder. I am using 64 bit Windows 8 OS. 

Now, I want to know how can I make a connection to the same database in c#.

Code snippets as example will be very helpful since I am a beginner here.

Thanks
