InfoPath Dev

Hi. How do I define a global variable of type int in C# in infopath?   I have tried like this

        private object _intNoNodes
        {
            get
            {
                return FormState["_intNoNodes"];
            }
            set
            {
                FormState["_intNoNodes"] = value;
            }
        }

but i get an error saying that:

Operator '+' cannot be applied to operands of type 'object' and 'int'

when I do something like this:

 intNoNodes = intNoNodes+1.

Thank you!

Change object to int and put (int) before the word FormState in the get{} block.

You'll need to assign an initial value to this variable before accessing it or you'll get an InvalidCastException.

 Thank you very much!
