I am getting into infinite loop in property setter

Question

public int Position
{
    get
    {
        if (Session["Position"] != null)
        {
            Position = Convert.ToInt32(Session["Position"]);
        }
        else
        {
            Position = 5;
        }
        return Position;
    }
    set
    {
        Position = value;
    }
}

my program calls the get and goes into if loop and then runs infitely into set code

Answer 1

The error is because in your set {} you are invoking the same setter recursively.

Correct code would be

private int _position;
public int Position
{
    get
    {
        if (Session["Position"] != null)
        {
            this._position = Convert.ToInt32(Session["Position"]);
        }
        else
        {
            this._position = 5;
        }
        return this._position;
    }
    set
    {
        this._position = value;
    }
}

Answer 2

Use a member variable or perhaps store it in the session.

private int _position;
public int Position
{
    get
    {
        if (Session["Position"] != null)
        {
            _position= Convert.ToInt32(Session["Position"]);
        }
        else
        {
            _position= 5;
        }
        return _position;
    }
    set
    {
        _position = value;
    }
}
