--- Basically u need to outsource the connection creation, read and write methods to another class and in Copy method u jus call these methods

write interface and class to implement connection class outside copy method.

 

IConnection

{

getConnetion();

Read(SqlConnection);

Write(SqlConnection);

}

Class CreateConn:IConnection

{

getConnetion(){--Connection logic here--}

Read(SqlConnection){--Read logic here--}

Write(SqlConnection){--Write logic here--}

Close(SqlConnection){--logic--}

}

 

Class A ,Class B, Class C unnayi

 

CreateCon con = new CreateConn()

ClassA ca= new ClassA(con);

 

ca.Copy();

 

ClassB cb= new ClassB(con);

 

cb.Copy();

 

ClassC cc= new Classc(con);

 

cc.Copy()

 

in class A/B/C create IConnection object and assign it using constructor

 

Similarly implement read/write methods.

 

Your copy method would be like this

 

Copy()

{

SqlConnection con = a.GetConnection();

a.Read(con);

a.Write(con);

a.Close(con);

}

Donniee.. yes.. this is what i exactly need.

 

I used your code.. kaani i have small problem ..what if i have to pass output of "read" method as "input" to Write method.. how should i do..? i can change the return type in interface... but Class A , Class B, Class C have different return types in their respective READ methods

 

 

 

 

 

just outline and naku telisindi rasa..hope this helps i dont have a strong command on this so get a second opinion

public interface IJambalHeart
{
    void Read(string conn);
    void Write(string conn);
}

public class ClassA: IJambalHeart
{
   public void Read(string conn)
   {
	 //ne istam
   }
   public void Write(string conn)
   {
	 //ne istam
   }
}

alage classB, class ClassA

public class SomeClass
{
	private readonly IJambalHeart jambal;
	
	public SomeClass(IJambalHeart jambal)
	{
		this.jambal = jambal;
	}
	
	//read method calling
	
	public void ReadMethod(string conn)
	{
		//here jambal is class
		jambal.Read(conn);
	}
	
	public void WriteMethod(string conn)
	{
		//here jambal is class
		jambal.Write(conn);
	}
}


from where you are calling just inst interface
IJambalHeart jambal = new ClassA(); //classc whatever you want
SomeClass cl = new SomeClass(jambal);
cl.ReadMethod(connection parameter);
c1.WriteMethod(connection para);

Tigerman.. Thanks for your time

 

one more question..

 

what if i have to pass output of "read" method as "input" to Write method.. how should i do..? i can change the return type in interface... but Class A , Class B, Class C have different return types in their respective READ methods
