‘本函数是一个find方法的增强函数，结合FindNext和FindPrevious方法，可以返回一组符合条件的单元格的集合；‘本函数返回一个Collection对象，里面储存了找到的单元格；‘本函数有两个必选参数：‘   1.SearchRange 用来存放需要查找的区域；‘   2.FindWhat用来存放需要查找的值;‘其余参数都是可选参数，与Find方法参数相同；‘无论是否查找到单元格，都会返回一个collection对象；‘我们用Collection.Count=0，来判断，没有找到匹配的单元格；Option ExplicitFunction FindPlus(SearchRange As Range, FindWhat As Variant, _                  Optional After As Range, _                  Optional LookIn As Variant = xlFormulas, _                  Optional LookAt As Variant = xlPart, _                  Optional SearchOrder As Variant = xlByRows, _                  Optional SearchDirection As Variant = xlNext, _                  Optional MatchCase As Variant = False, _                  Optional MatchByte As Variant = True, _                  Optional SearchFormat As Variant = False) As CollectionDim FoundCell As Range ‘存放找到的单元格区域；Dim AfterCell As Range ‘存放查找的起始单元格；Dim FoundCol As Collection ‘存放找到单元格区域的集合；Dim firstAddress As String ‘存放第一次找到的单元格的地址Set FoundCol = New Collection ‘Collecion类实例化为对象‘下面这个判断语句完成对After参数值的控制If After Is Nothing ThenElse  Set AfterCell = After ‘如果after参数不为空，这用提供的after参数值End If‘查找第一个符合条件的值Set FoundCell = SearchRange.Find(what:=FindWhat, After:=AfterCell, _                              LookIn:=LookIn, _                              LookAt:=LookAt, _                              SearchOrder:=SearchOrder, _                              SearchDirection:=SearchDirection, _                              MatchCase:=MatchCase, _                              MatchByte:=MatchByte, _                              SearchFormat:=SearchFormat)If Not FoundCell Is Nothing Then    firstAddress = FoundCell.Address ‘如果找到第一个值，然后把单元格地址赋值给FirstAddress变量        ‘下面的循环是在区域里不断查找需要的值，并不断添加到FoundCol集合    Do      FoundCol.Add FoundCell ‘把找到的单元格赋值给FoundCol对象            ‘根据SearchDirection参数，判断是向上搜索，还是向下搜索      If SearchDirection = xlNext Then        Set FoundCell = SearchRange.FindNext(After:=FoundCell)      Else        Set FoundCell = SearchRange.FindPrevious(After:=FoundCell)      End If    Loop Until (FoundCell Is Nothing) Or (FoundCell.Address = firstAddress) ‘经典用法，只要找到单元格和第一个找到的单元格地址不一样，就一直循环End IfSet FindPlus = FoundCol ‘把集合对象赋值给函数名End Function
