Suppose

public class A

{

int a=5;

void sum()

{int a=5,b=5,c;

c=a+b;

}

public class B

{

int b=6;

void getmethod(string A,int a)

{

//code

}

So How can i do it?

Before all, you promise to read this article talking about why cross assembly reference i.e. scenario you mentioned here, is a bad practice. https://stackoverflow.com/questions/10204277/circular-class-references-bad-practice

I am continuing here by taking your question as part of a learning practice than a standard to follow. I understood that you need a class name to be passed as a string type rather than an object. If so, below code worked for me in a console application.

NB: This is a happy flow and things will change depend on using static types and all.
namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            A a = new A();
            a.sum();

            Console.ReadLine();

        }

    }

    public class A
    {
        int a = 5;
        public void sum()
        {
            //Getting full classname
            string className = this.GetType().FullName;
            B bobj = new B();
            bobj.getmethod(className, 10);
            int a = 5, b = 5, c;
            c = a + b;
        }
    }

    public class B
    {
        int b = 6;
        public void getmethod(string A, int a)
        {
            //Loading and creating the passed class.
           A Aobj =  Assembly.GetExecutingAssembly().CreateInstance(A) as A;
            Aobj.sum();
        }
    }
}
Takeaway here is using C# reflection, https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/reflection, you take class names dynamically and also load it dynamically.

@Amit, As u said about public,then i have already tried it ,but not working.

This is because your method is not public, making the access specifier to public will be your expected output

@Amit,As U mention in code that i just create objof Class A
But the problem when i will create obj of Class B
like :
In main Class
B obj=new b();
-------------------
obj.getmethod();
---------------------
Then This part will give u error So what Parameter u will pass then in obj.getmethod();

1. // you can use the class object directly
3. public class B
4. {
5. int b=6;
6. void getmethod(A aClass, int a)
7. {
8. //Use method of aClass here
9. }
10. }
