DataGridViewRow數值順序

Question

如何將DataGridViewRow按數字順序排序？

我的代碼：

Dim Name As New List(Of String) 
Dim Price As New List(Of Integer) 

    For x = 0 To Math.Max(Name.Count, Price.Count) 
       If x < Name.Count AndAlso x < Price.Count Then 
       Dim row As String() = New String() {Name(x), Price(x)} 
       DataGridView1.Rows.Add(row) 
      End If 
     Next 

價格排例如：

1345 
1533 
4555 
6744

你已經得到了他們作爲兩個單獨的列表......我要一個飛躍，讓你需要的假設以這種格式保存源數據......將它們放在兩個列表中，您目前對它們的位置有依賴性。因此，使用可分類的集合將它們配對起來

例如，

Imports Microsoft.VisualBasic 
Imports System.Collections.Generic 
Imports System.Data.Linq 

    Dim Name As New List(Of String) 
    Dim Price As New List(Of Integer) 
    Dim Sortable As New List(Of KeyValuePair(Of String, Integer)) 

    'Your checking that you weren't going past the last pair was an odd one 
    For x = 0 To Math.Min(Name.Count, Price.Count) - 1 
     'Pair them up so you can sort them together not having to try to match between two lists 
     Sortable.Add(New KeyValuePair(Name(x), Price(x))) 
    Next 

    'now you can sort it 
    Sortable = (From item In Sortable Order By Convert.ToInt32(item.Key) Select item).ToList() 

    'now stick it in the grid view, You might be able to base the grid view on the 
    'DataGridView1.DataSource = Sortable 
    'DataGridView1.DataBind() 
    'depends on how it is defined/configured, 
    'but for now let us return to your original code.... 
    For Each kvp As KeyValuePair(Of String, Integer) In Sortable 
     Dim row As String() = New String() {kvp.Key, kvp.Value.ToString("$0.00")} 
     DataGridView1.Rows.Add(row) 
    Next
