    Sub Main()
	' The input string.
	Dim value As String = "1email:string:string"

	Dim m As Match = Regex.Match(value,  "\d+(.*)",  RegexOptions.IgnoreCase)

	If (m.Success) Then
	    Dim lineWithoutNumber As String = m.Groups(1).Value
	    Console.WriteLine(lineWithoutNumber )
	End If
    End Sub

Sub Main()
      
     'Input string
     Dim strString as String = "1email:string:string"
     
     'Get the position of "email" and add 1 since Mid needs to start with 1 
     'Cut out the part of the string we want via Mid since we now know the correct position to trim from
     strString = Mid(strString, strString.IndexOf("email") + 1) 
     
     'Show the output   
     Console.WriteLine(strString)
        
End Sub
