Calling interface driven method from one project to another

namespace Project1

{

public interface IInterface1

{

void Method();

}

public interface IInterface2 : IInterface1

{

void Method();

void Method2();

}

// Here we are implementing methods for get and sent data to database

public class GetSentData: IInterface1

(

void Method();

void Method2();

)

}

note: We are making a .dll of above mentions interfaces and class.

//This is a another solution

//I add reference of Project1 into project2

Namespace project2

{

public class Acess

{

//Here we want to call above class method by using the interface driven class

IInterface1 myinterface=new GetSentData();

myinterface.Method();

//Like This but am getting error as: Object is not set to an instance of object

}

//Please Suggest with your valuable answers

Hi,

I dont know what you want to achieve with this program, it seems not compiliing when I copied your code in a new class lib. project, I did some modifications.

First of all a simple suggestion: can't you give meaningful names to classes, methods and interfaces? these names are just confusing.

the main issue I see is you need to explicitly implement Method() of IInterface1, then it will work ok.

public class GetSentData : IInterface1
{
void IInterface1.Method()
{
//do something here
}
void Method2()
{
//do something here
}
}

Download attached code and see, next time always post your code as zip file so someone can directly work on it.
