c# - MDI form with login form does not return to login after closing MDI -

i have mdi form user can access after login, when user closes session should go login form instead opens login form , closes , mdi form, too.

i calling close() method when user click log off button.

i'm not sure how you're doing use this

//on login form private void login() {    //check if login right    mdiform formname = new mdiform();    this.hide(); // login form not visible    formname.showdialog(); //opens mdi , whatever needs    this.show(); //after mdi closes go here }
