Question

Is there a way to detect a Chinese character in a string which is build like this:

dim test as string = "letters 中國的"

Now I want to substring only the Chinese characters. But my code is database driven, so I can’t substring it, because the length is always different. So is there a way I can split the string, from the moment I detect a Chinese character?

Answer 1

I think you can use regexp like in the following example, didn’t test and I haven’t code using VB.net for years So syntax may be not correct.

Dim m As Match = Regex.Match(value, "[\u4e00-\u9fa5]+", 
                 RegexOptions.IgnoreCase)

' If successful, write the group.
If (m.Success) Then
    Dim key As String = m.Groups(1).Value

End If
