我在尝试从 .txt file 导入信息时遇到问题。我在文件中有这些数据：

我想为任何 BUS (NODO) 提取信息：

Name                             Vnom    ( MW ) 
ALICURA     500        2         500      251.8 
SANTO TOME  500  2               500      101.2
ALMAFUERTE    1.0     3            1       -9.5

我编写了这段代码，但只适用于第一个：

Private Sub BarrasIny_Click()
    Dim myFile As String
    Dim text As String
    Dim quote As String
    Dim textline As String

    myFile = "C:\Users\tvelis\Desktop\CFCT_por_barra2.txt"

    Open myFile For Input As #1
        Do Until EOF(1)
            Line Input #1, textline
            text = text & textline
        Loop
    Close #1

    quote = InStr(text, "---- NODO")
    Range("A1").Value = "Barra"
    Range("B1").Value = "Tension"
    Range("c1").Value = "MW"

    Range("A2").Value = Mid(text, quote + 103, 30)
    Range("B2").Value = Mid(text, quote + 136, 3)
    Range("C2").Value = Mid(text, quote + 145, 5)
End Sub

我该如何做一个循环并从任何总线（NODO）中提取信息？

我尝试了以下方法，我相信它非常接近您想要实现的目标，使用计数器检查 NODO 并获取下面两行的值，然后获取文本行的值并将它们拆分放入一个数组，然后循环遍历该数组以将值放入工作表中：

Private Sub BarrasIny_Click()
    Dim myFile As String
    Dim text As String
    Dim quote As String
    Dim textline As String
    Dim ws As Worksheet: Set ws = Sheets("Sheet1")
    'declare and set your worksheet, amend as required
    Dim arr(0) As Variant
    myFile = "C:\Users\tvelis\Desktop\CFCT_por_barra2.txt"
    counter = 0

    Open myFile For Input As #1
        Do Until EOF(1)
            Line Input #1, textline
            counter = counter + 1
            If InStr(textline, "--- NODO") > 0 Then counter = 0

            If counter = 2 Then
                LastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row + 1
                b = 2
                arr(0) = Split(textline, " ")
                For c = LBound(arr(0)) To UBound(arr(0))
                    If arr(0)(c) <> "" Then
                        If Not IsNumeric(arr(0)(c)) Then
                            ws.Cells(LastRow, 1).Value = Trim(ws.Cells(LastRow, 1).Value & " " & arr(0)(c))
                            y = LastRow
                        Else
                            ws.Cells(y, b).Value = arr(0)(c)
                            b = b + 1
                        End If
                        x = x + 1
                    End If
                Next c
            End If
        Loop
    Close #1

    ws.Range("A1").Value = "Barra"
    ws.Range("B1").Value = "Tension"
    ws.Range("C1").Value = "MW"
End Sub
