What is the loginBLL class? Is it something from a library, or something you've created yourself?

Either way, the loginBLL class is either internal or private in the assembly where it comes from, and hence you'll not be able to use it in a different assembly.

Exactly, my (virtual) 5.

loginBLL is create by myself . and it is not internal

You should post the code of that class then, use the "Improve question" to add this code.

thank you

Your class or method should be public to access in different assembly.

please explain more

Suppose you have two project one is your web application and another is class library (like Business access Layer). Now you want to use a method of class that class in Business Access Layer in your web application page then you need to care some point. These are
1. You need to add reference of class library project to web application.
2. Class libraries classes should be public.
3. These method would be access in web application of class library classes, should be public.

Thanks.

one more thing By default C# classes are internal.

Just a guess, but did you create loginBLL as a Singleton class? If so, then you need to look at how you get the instance.
The error message indicates that the loginBLL constructor is not publicly available, so either it's a Singleton, or you need to create an instance of a derived class in order to use it.

I'm going to ask what might seem like a blindingly obvious question, but is your loginBLL class declared as public? In other words is it declared as

C#

public class loginBLL
{
}

If it is, does it have a public constructor, i.e.

C#

public loginBll() {}

If it has a default constructor that isn't public then you won't be able to instantiate it from outside the loginBLL class.
