Public Class Form1

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        Dim arry() As String

        arry = Split(TextBox1.Text, vbCrLf)     '将每行内容放到数组中,

        Dim i, j As Integer

        TextBox1.Text = ""

        For i = 0 To UBound(arry)

            If Len(Trim(arry(i))) > 0 Then '

                j = j + 1

                TextBox1.Text = TextBox1.Text & CStr(i + 1) & ". " & arry(i) & vbCrLf '输出的每一行内容 

            End If

        Next

        MsgBox(TextBox1.Text)

    End Sub

End Class



把上述代码放入textbox1中,输出结果如下:
