如何排序列表框与字母和数字上升的用数字vb.net

问题描述

我有这样的一个列表框：

 测试| 10
名称| 44
布拉布拉| 16
 

和我想在年底（10 44 16），这些项目通过他们的数量进行排序，以使他们成为责令这样的：

 名称| 44
布拉布拉| 16
测试| 10
 

解决方案

看起来你实际上是在寻找降序排列。不管怎么说，这里是从一个列表解决另一个问题：

 昏暗myList中作为列表（字符串）= {测试| 10，名称| 44，布拉布拉| 16}了ToList
昏暗orderedList方式列表（字符串）=（从项目在myList上顺序按item.Substring（item.IndexOf（|）+ 1）降序选择项）.ToList
 

编辑：这将项目作为字符串进行排序，这意味着如果你有44，16，100，10，它看起来像这样进行排序后：44，16，100，10，这可能不是什么你想要的，所以你应该分析该号码的开出成整数，让他们排序数字。试试这个：

 昏暗myList中作为列表（字符串）= {测试| 10，名称| 44，布拉布拉| 16，富| 100}了ToList
昏暗orderedList方式列表（字符串）=（从项目在myList上顺序按Integer.Parse（item.Substring（item.IndexOf（|）+ 1））降序选择项）.ToList
 

I have a listbox with something like this:

test|10
name|44
blabla|16

and I want sort those items by the number they have at the end (10 44 16), such that they become ordered like this:

name|44
blabla|16
test|10

解决方案

It looks like you are actually looking for descending order. Anyways, here is a solution from one list to another:

Dim myList As List(Of String) = {"test|10", "name|44", "blabla|16"}.ToList
Dim orderedList As List(Of String) = (From item In myList Order By item.Substring(item.IndexOf("|") + 1) Descending Select item).ToList

EDIT: This will sort the items as strings, which means that if you have 44, 16, 100, and 10, it would look like this after being sorted: 44, 16, 100, 10. This is probably not what you want, so you should parse the numbers out into integers so that they sort numerically. Try this:

Dim myList As List(Of String) = {"test|10", "name|44", "blabla|16", "foo|100"}.ToList
Dim orderedList As List(Of String) = (From item In myList Order By Integer.Parse(item.Substring(item.IndexOf("|") + 1)) Descending Select item).ToList
