ubb代码转换问题！

[NetFire]

以下是我自己写的一个ubb的类。但是有点小问题。
主要问题就是无法将回车认出来，从数据库中读出的文本，都没有换行。请指点阿！
下面是我的ubb类的代码——

Public Class ubbconvers

'////convers start/////
Public Function htmltoText(ByVal chr As String)
If chr Is Nothing Then
Return ""
Else
chr = chr.Replace("'", "''")
Return (chr)
End If
End Function

Public Function Texttohtml(ByVal chr As String)
If chr Is Nothing Then
Return ""
Else

过分了，也没人顶一下。虽然我不懂，我也想学一手呀！兄弟们，关注一下啊。
等待中。。。。。。。。。。

换行

string xxx = myReader["Content"].ToString().Replace( " ", " " ).Replace( Convert.ToString( ( char ) 10 ), " " ).Replace( Convert.ToString( ( char ) 13 ), "<br>" );

[NetFire]

我搞定了
resultString = resultString.Replace(Chr(13) & Chr(10), "<br>")
