Question

Hi I have this program that I am writing that uses the struct below. I keep getting a stackoverflow error and the exception is stops the program at the fist bracket in public string sessionID set…(where the “>>>” is).

  public struct SessionStruct 
{
    public string sessionID
    {
        get
        {
            return sessionID;
        }
        set
  >>>   {
            sessionID = value;
        }
    } 
    public DateTime time
    {
        get
        {
            return time;
        }
        set
        {
            time = value;
        }
    }

    public string type
    {
        get
        {
            return type;
        }
        set
        {
            type = value;
        }
    } 
};

Here is the code that sets the struct:

if (type == "11" || type == "9")
                {
                    s.sessionID = attributeArray[0].ToString();
                    s.time = DateTime.Now;
                    if (type == "9")
                        s.type = attributeArray[4].ToString();
                }
                else
                {
                    s.sessionID = null;
                    s.time = DateTime.Now;
                    s.type = null;
                }

Thanks for the help in advance…

Your property is calling itself over and over again. The property really needs a backing store to store the data in, which is typically a private variable:

private string _sessionID;

public string sessionID
{
    get
    {
        return _sessionID;
    }
    set
    {
        _sessionID = value;
    }
} 

Or let the compiler do it for you:

public string sessionID
{
    // compiler will create a backing store for you
    get; set; 
}
