vb.net列表如何排序和显示

Question

I have a list that is is populated by a DB query:

Dim bplist As List(Of KeyValuePair(Of String, Integer)) = New List(Of KeyValuePair(Of String, Integer))

What I want to do is sort the list in order of largest Integer to smallest and then display both Key and Value of this list in the HTML part of my .aspx page.

I've googled around quite a bit and only managed to confuse myself. Can someone please help me with this? Thanks.

Answer 1

You can use a linq query to accomplish this

dim bplist as List(Of KeyValuePair(Of String, Integer)) = New List(Of KeyValuePair(Of String, Integer))
dim sortedList as List(Of KeyValuePair(Of String, Integer)) = bplist.OrderByDescending(Function(x) x.value).toList

In order to bind the keys and values to HTML, I would suggest taking a look at repeaters

Note

This is assuming that when you say you want to sort by the highest to lowest integer, that you are meaning the value
