[可能重複] How to customize sort order of strings

對於一個據稱訂購該列表同樣的問題排序順序：

bufallo@2000 
lice@20 
cell@1 
rat@150 
cow@10000 

...在此列表：

cow@10000 
bufallo@2000 
rat@150 
lice@20 
cell@1 

假設我忽略了小於100的數字部分 - 即刪除另外兩個：

cow@10000 
bufallo@2000 
rat@150 

這可能嗎？我試過下面的代碼，但我不知道如何自定義小於100的數字部分，從而刪除其餘部分。

Dim number As Int32 = Int32.MinValue 
Dim orderedLines = From line In TextBox1.Lines 
        Let parts = line.Split("@"c) 
        Let numericPart = parts.Last() 
        Let success = Int32.TryParse(numericPart, number) 
        Select LineInfo = New With {line, number} 
        Order By LineInfo.number Descending 
        Select LineInfo.line 
' if you want to reassign it to the TextBox: 
TextBox1.Lines = orderedLines.ToArray()

我的VB LINQ體驗相當稀少，但這是你想要的嗎？

Dim orderedLines = From line In TextBox1.Lines 
        Let parts = line.Split("@"c) 
        Let numericPart = parts.Last() 
        Let success = Int32.TryParse(numericPart, number) 
        Select LineInfo = New With {line, number} 
        Where number >= 100  ' something like this? 
        Order By LineInfo.number Descending 
        Select LineInfo.line
