需要帮助阅读下一行

问题描述

您好我正在使用stringreader从richtextbox中读取数据字符串。数据正被添加到richtextbox中，我需要在添加到标签时显示新添加的行，以便在将新行添加到richtextbox时标签将更改。类似于读取结束的流程读取器。



请帮助我不确定在这种情况下使用什么循环



提前谢谢





这是我尝试过但由于某种原因我只获得了第一个添加的条目。下一个添加的条目未显示在标签中

Hello I am using stringreader to read strings of data from a richtextbox. Data is being added to the richtextbox and I need to show the new added line when its added to a label so that the label will change when a new line is added to the richtextbox. something like read to end for streamreader.

please help I am unsure what loop to use in this case

thank you in advance


Here is what i have tried but for some reason i only get the first added entry. the next added entry does not show in the label

Dim reader As New StringReader(RichTextBox2.Text)
        Dim tmp As String = reader.ReadToEnd
 Dim MD As Match = md.Match(tmp)
For Each M As String In RichTextBox2.Lines
           If M.Contains(MD.ToString) Then
               Label4.Text = MD.ToString
           End If
       Next M
