You can use Session or HttpContext.Current.Items .If you value is a temporary variable I suggest using HttpContext.Current.Item instead of session since it will be gone as soon as current HttpContext is gone but items that are stored in Session won't be cleared until session is expired.

Session["var"]=value;

var value=Session["var"];

HttpContext.Current.Items["var"]=value;

var value=HttpContext.Current.Items;
