.Net API/DLL for scanning files

Hi,

We are using Symantec 12.1.1101.401.105 in my system. We need to scan some files from our custom C# application. Can you please refer the link to download the appropriate DLL?

We found some DLLs in the bin folder of Symantec folder in our machine. Is there is a DLL which we can use to scan files. If so please name the DLL.

Thanks.
