推荐答案

尝试一下:

Try this:

Dim sFileName As String = String.Empty, sLine As String = String.Empty, sCols() As String = Nothing
Dim objReader As System.IO.StreamReader = Nothing

Try
    sFileName = "F:\myCard.vcf"
    Me.Label1.Text = sFileName & vbCrLf & vbCrLf
    objReader = New System.IO.StreamReader(sFileName)
    Do While objReader.Peek >= 1
        sLine = objReader.ReadLine()
        sCols = sLine.Split(":") 'split text by :
        Me.Label1.Text = Me.Label1.Text & sCols(1) & vbCrLf
    Loop
    objReader.Close()

Catch ex As Exception
    MsgBox(ex.Message, MsgBoxStyle.Exclamation, "Error...")
Finally
    objReader.Dispose()

End Try
