public B Getval()
There is no type called B. What makes you think there is ? It would help if you told us the exact error message, and the line that generates it, but at first glance, I think this is your problem. Your other problem is that this is the ASP.NET forum, which this question has NOTHING to do with, in any form. Pls use the C# forum in future.

You also don't return anything. I *think* you wanted to write public BB Getval() { BB b=new BB(); b.A=5; b.B=1; return b; } It's unusual for a non static method to return an instance of a class, I need to create a BB to call Getval, and get another BB.

Your propertys are completely wrong. You're trying to return _a but when you're setting the property you set _deno to a. Try this
class AA
{
public AA{}
private decimal _a;
public decimal A{ get { return _a; } set { _a = value; } }}
