想替换字符串中的句号，末尾的句号除外，请蓝老师帮忙改一下，谢谢！
代码结果为"你好，你好，你好。"

\'\'\'
Dim str As String = "你好，你好。你好。"
.......

Dim lst As new List(Of String)
If lst.Count >= 1 Then
    For i As Count = 0 To lst.Count-1
        If i <> lst.Count -1 Then
            lst(i).Replace("。","，")
        End If
    Next
End If
Output.Show(lst)

lst(i) = lst(i).TrimEnd("。").Replace("。","，") & "。"

1、这样没问题：

\'\'\'
Dim str As String = "在控件中每输入，或删除一个字符。都会触发TextChanged事件，"
str = str.TrimEnd("。").TrimEnd("，").TrimEnd("；").Replace("：","").Replace("；","，").Replace(",","，").Replace("、","，").Replace("。","，") & "。"
Output.Show（str）

 

2、文本框textchang代码，在文本框中编辑时为什么出现一些句号单独成了一段，也删不掉：

Dim txt As WinForm.TextBox = e.Form.Controls("TextBox01")
If txt.text.EndsWith(chr(10)) = False Then
    Dim ary() As String = txt.Text.Split(chr(13))
    Dim str As String = ""
    For Each s As String In ary

        s =s.TrimEnd("。").TrimEnd("，").TrimEnd("；").Replace("：","").Replace("；","，").Replace(",","，").Replace("、","，").Replace("。","，") & "。"
        If s <> chr(10) Then
            str &= "    " & s.trim & vbcrlf \'行首空格
            str &= vbcrlf & ""
        End If
    Next
    systemready = False
    txt.text = str
    systemready = True
End If
