本文介绍了从列表视图中的条目生成简短的多个报告（VB.NET）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 你好，我的名字很好，我需要一个任务的帮助，我在vb.net上的项目工作。我在表单上有一个列表视图，列表视图有4个固定列和尽可能多的行，基于点击几个按钮的用户条目。如果用户点击服装按钮，则会插入一行，如下所示：hello there, my name is ade and i need help on a task, am working on project in vb.net. i have a listview on a form, the listview has 4 fixed columns and as many rows as possible based on user entries at the click several buttons. if a user clicks a garment button a row is inserted and it looks like this:Desc, Amount Quantity No. Piece-----------------------------------------------2pc suit 500 2 2 （插入服装及其成本，带来的服装数量以及制作服装类型的件数） 当他点击一个颜色按钮时，现在插入了另一行，使列表视图看起来像这样：(inserting a garment with its cost, the quantity of garments brought and how many pieces makes that garment type)when he clicks a color button another row is inserted now making the list view look like this:Desc, Amount Quantity No. Pieces-----------------------------------------------------------2pc suit 500 2 2black 当他点击一个布料按钮时，现在插入另一行，使列表视图看起来像这样：when he clicks a fabric button another row is inserted now making the list view look like this:Desc, Amount Quantity No. Pieces------------------------------------------------2pc suit 500 2 2blackwool 上面提到的任务我可以实现，但现在点击一个按钮我需要生成一张票或发票以及一些标签（简短的描述/细节）报告。生成这些标签是问题，从上面你可以看到已经输入（插入）两件2件套装和2件组成2件套装（2件套装）这意味着4个标签（即2件次数量2）。 br /> 这些标签将带有物品名称，颜色，面料，数量和总数量（将其列为1of4,2of4,3of4和4of4）。 这样的事情：The above mentioned tasks i can achieve, but now at the click of a button i need to generate a ticket or invoice along with some tags(short descriptive/details) report . Generating these tag is the issue, from the above you can see that two 2piece suit has been entered (inserted) and 2 items make up a 2pc suit( 2 piece suit) this implies 4 tags (that is 2piece times quantity 2).these tags will carry name of item, color, fabric, amount and total quantity (listing it as 1of4,2of4,3of4 and 4of4).something like this:==================================================== (1/4) Due date 23/05/2017 User:2 == customer name: Tom Jones Contact No: 08023345677== 2pc Suit 500/blue/cotton ==================================================== 当你现在有这样的东西时会变得更复杂，It gets more complicated when you now have something like this,Desc, Amount Quantity No. Pieces-------------------------------------------------2pc suit 500 2 2blackwool-------------------------------------------------Shirt 200 1 1bluecotton-------------------------------------------------Shirt 200 1 1whitecotton-------------------------------------------------Shirt 200 1 1pinkcotton------------------------------------------------- 请欣赏任何帮助，因为卡住了，不知道从哪里开始。关于生成这些标签 热情的问候 我尝试了什么： i在这个问题上还没有尝试任何东西 请欣赏任何帮助，因为卡住了，不知道从哪里开始。生成这些标签please will appreciate any assistance , as am stuck and don't know where to start. on generating these tagswarm regardsWhat I have tried:i have not tried anything yet on this very issueplease will appreciate any assistance , as am stuck and don't know where to start. on generating these tags推荐答案invoice ( invoice no., date of sale, item on invoice ( selled object /a garment in your case/, amount, price, etc. ) ),seller (seller no., name, etc.),buyer (buyer no., name, etc.) 每个对象应表示为一个类 [ ^ ]，其中包含多个属性。例如，客户可以定义为：Every single object should be represented as a Class[^], which contains several properties. For example, Customer may be defined as:Public Class CustomerPrivate sName As String = String.EmptyPrivate sContactNo As String = String.EmptyPublic Sub New()'default - empty constructorEnd SubPublic Sub New(ByVal _Name As String, ByVal _ContactNo As String)sName = _NamesContactNo = _ContactNoEnd SubPublic Property Name As StringGetReturn sNameEnd GetSet (value As String)sName = valueEnd SetEnd PropertyPublic Property ContactNo As StringGetReturn sContactNoEnd GetSet (value As String)sContactNo = valueEnd SetEnd PropertyEnd Class 所以，创建客户对象：So, to create Customer object:Dim cust As Customer = New Customer("Maciej Los", "0123654789") 我不想提供完整的代码，因为这是你的工作。结论是：你应该从基础开始： Visual Basic中的对象和类Microsoft Docs [ ^ ] 定义类（Visual Basic）| Microsoft Docs [ ^ ] 深思熟虑：创建自己的收藏类 [ ^ ] 祝你好运！I wan't to provide complete code, because it's your job. Conclusion is: you should start from basics:Objects and classes in Visual Basic | Microsoft Docs[^]Defining Classes (Visual Basic) | Microsoft Docs[^]Walkthrough: Creating Your Own Collection Class[^]Good luck! 这篇关于从列表视图中的条目生成简短的多个报告（VB.NET）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
