How to use a class from one assembly into another

[Daniela Roman]

hello,

I want to create a class in a library:

public class GetHello
{
private string aa = "Hello world";
public GetHello()
{
//
// TODO: Add constructor logic here
//
}
public string GetContent()
{
return aa;
}
}

Then I create a simple project and I want to use the GetContent to return
the string.
What I did was to add a reference to the dll created by the library class,
from the Projects tab.
then I create an object:
MyData_Object myObj = new MyData_Object() ;

trying to use myObj, it does not see the method I created earlier:
GetContent

Thank you

[Daniela Roman]

I forgot to mention:

namespace MyData_Object

{

}

Daniela,

>public class GetHello

[...]

>MyData_Objec t myObj = new MyData_Object() ;

trying to use myObj, it does not see the method I created earlier:
GetContent

So is the class called GetHello or MyData_Object?

Hello Daniela,

Have u pointed "using" statement with the namespace where your class locate?

You can only create an object of a class, not a namespace.

Thanks
I got the problem, I need to use the namespace in the USING reference and
then the class will be seen entirely.
Is this the approach in N-tier architecture? I mean to create each layer in
a library and then make references to them?

Thank you

What you need to do is to include the *Project* for the class library in the
Solution for any application that wants to use it. You can include a project
in as many Solutions as you like. I have a single class library Project that
is included in every Solution that I have written. After including the
Project in the Solution, create a reference to the *Project* in the other
Project. Visual Studio will manage the rest.
