VB逐行读取TXT

VB逐行读取TXT,我需要vb能实现逐行读取txt文本，当读完第一行后，赋值在textbox中，再次单击command后，读第二行，赋值在textbox中，以此类推，直到读完txt文本。恳请同在一片蓝天下的中国人帮帮忙啊！

Answer 1

Function GetLineStr(FileSpec As String) As String() '获取filespec路径下文件每一行内容，并写入数组函数中
Dim i As Integer
Dim TempStr As String, Temp() As String
Dim FileNum As Integer
FileNum = FreeFile
Open FileSpec For Input As #FileNum
Do While Not EOF(1)
Line Input #FileNum, TempStr
i = i + 1
ReDim Preserve Temp(1 To i) As String
Temp(i) = TempStr
Loop
GetLineStr = Temp
Close #FileNum
End FunctionPrivate Sub Command1_Click() '调用示例
Dim FileSpec As String 'txt路径
Static i As Integer
Dim LineStr() As String
i = 1
If i = UBound(LineStr) Then
MsgBox "文件已结束"
i = 1
End If
FileSpec = "d:\1.txt"
LineStr = GetLineStr(FileSpec)
text1.Text = LineStr(i)
i = i + 1
