How to Compare two datatable objects

An easy solution to compare two datatable object with the support of business object classes.

public static DataTable CompareObject(object x, object y)
        {
            //return if input objects are of not same type
            DataTable dtComp = new DataTable();

            dtComp.Columns.Add(DtCol2);
            dtComp.Columns.Add(DtCol3);
            Type type = x.GetType();
            Type type1 = y.GetType();
            if (!type.Equals(type1))
                return dtComp;
          
            PropertyInfo[] properties = type.GetProperties();
            FieldInfo[] fields = type.GetFields();
            int compareValue = 0;
            try
