C#怎么一行一行的读取richtextbox内容？
一个Timer。一个richtextbox。一个text。一个richtextbox里面有多行文本，时钟周期是10秒，每十秒读取一行richtextbox的一行内容添加到TEXTBOX里面。就像桌面显示歌词一样。怎么实现？大神们？
一次性把ricthextbox里的文本读取出来 然后按照行（'\n'）数分割成数组保存 time每10秒显示一行

代码如下:
Public Class Form1
Public i As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim counter As Integer
Dim tempArray() As String
tempArray = RichTextBox1.Lines
For counter = 0 To tempArray.GetUpperBound(0)
Console.WriteLine(tempArray(counter))
Next
If (i < counter) Then
Label1.Text = RichTextBox1.Lines(i)
Else
If (i = counter) Then
i = 0
End If
End If
i = i + 1
End Sub
End Class
Public Class Form1
Public i As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim counter As Integer
Dim tempArray() As String
tempArray = RichTextBox1.Lines
For counter = 0 To tempArray.GetUpperBound(0)
Console.WriteLine(tempArray(counter))
Next
If (i < counter) Then
Label1.Text = RichTextBox1.Lines(i)
Else
If (i = counter) Then
i = 0
End If
End If
i = i + 1
End Sub
End Class
