Hi,

i'm creating an data Access layer over their i faced this requirement.That is example i'm checking the number of existence of a name in a table over their i create a function and pass parameter over their one parameter i need the occurrence. For this i need to use pass by reference method.

 The reference variable is declared as ref in prefix .

Example

    protected sum add = new sum();

    protected void Page_Load(object sender, EventArgs e)

    {

        int _i = 10;

        int _j = 20;

        int _result=0;

        add.add(ref _result, _i, _j);

        lbl_Rslt.InnerText = _result.ToString();// displaying the result

    }

    public void add(ref int _result, int _P, int _k)

    {

        _result = _P + _k;

    }
