Generic Types

Question

User1820827484 posted

Hello Community, 

I have following scenario! 

I developed an interface. 

public interface iDataAction
    {
        int create();
    }

There is another class which is implementing the iDataAction interface. 

public class ContactBO: iDataAction
    {

        public int create() { return 0; }
        // constructor
        public ContactBO() { 
        }
    }

Infact, I want to implement this interface to ensure that each Business Class must implement the CRUD operation for database. From presentation layer, I need to post the ContactDTO  object to access in create(). So how can I make Generic Type Param?
