Question

Below is my code:

using (pgsqlConnection conn = new pgsqlConnection(connStr))
{

} //automatically Dispose()    
public class v2Connection:IDisposable
{

    public void Dispose()
    {
        //close the connection and release resources
    }

}

This is what I have written so far in my Connection class (v2Connection). It is giving error on pgsqlConnection and it is obvious that at present neither I have a class with this name nor an Interface.

I want to add two function: Open and Close. I am not following where should I call Open() and Close()? If I create an interface with the name: IConnection with two methods:

int Open();
int Close();

How to use this interface in the above code?

Answer 1

You could have a wrapper for your connection :

using (MyConnectionWrapper conn = new MyConnectionWrapper ())
{

}

With MyConnectionWrapper :

 public class MyConnectionWrapper : IDisposable
    {

        void OpenConnection();
        void CloseConnection();
        void Dispose();
    }

and in the constructor of your class

public MyConnectionWrapper ()
{
    OpenConnection();
}

and in the Dispose function :

public void Dispose()
{
   CloseConnection();
}
