Android Question Return only numbers and letters from string

[aaronk]

Hi,

If I have a string, how can you return only numbers and letters only ?

For Example:

Dim MyString as string = "ABC.1>234?"
' how can I make it only return ACB1234 only ?

I know I can use:

MyString = MyString.Replace(".","")

However, I was hoping not to use the 'replace' function.

Is there a way to make a string only contain letters and numbers only ?

Sub OnlyNumbersOrLetters (s As String) As String
   Dim m As Matcher = Regex.Matcher("[a-zA-Z0-9]+", s)
   Dim sb As StringBuilder
   sb.Initialize
   Do While m.Find
     sb.Append(m.Match)
   Loop
   Return sb.ToString
End Sub

or

Dim MyString As String = "ABC.1>234?"
Log( Regex.Replace("[^a-zA-Z0-9]",MyString,"") )
