如何在VB中简化几个类似的集合文件

Dim collectionFiles(3) As String
collectionFiles(0) = "file1.txt"
collectionFiles(1) = "file2.txt"
collectionFiles(2) = "file3.txt"
collectionFiles(3) = "file4.txt"

For i As Integer = 1 To 4
    Dim filePath As String = "file" & i & ".txt"
    ' 在此处处理文件
Next

Dim collectionFiles As New List(Of String)
collectionFiles.Add("file1.txt")
collectionFiles.Add("file2.txt")
collectionFiles.Add("file3.txt")
collectionFiles.Add("file4.txt")

For Each filePath In collectionFiles
    ' 在此处处理文件
Next

Dim collectionFiles As New List(Of String)
collectionFiles.Add("file1.txt")
collectionFiles.Add("file2.txt")
collectionFiles.Add("file3.txt")
collectionFiles.Add("file4.txt")

Dim filteredFiles = From file In collectionFiles Where file.Contains("2")

For Each filePath In filteredFiles
    ' 在此处处理文件
Next
