Static member

It describes the use of static.

When and where we can use static member,

 Usually we can access another form variables after creating instance of the form like

            FrmMain frm = new FrmMain();
            frm.aa = "";

When aa declared as public like

            public string aa="";


Here by ,when coming to static member we can access like

            FrmMain.aa = "";

if we declare variable as static

public static string aa="";
