Android Question How do I set profile image as first letters of first and last name like Telegram?

Dim UserName As String = "Aeric Poon"
Dim Names() As String = Regex.Split(" ", UserName.Trim)
Dim Initials As String

If Names.Length > 1 Then
    'Initials = Names(0).SubString2(0, 1) & Names(Names.Length - 1).SubString2(0, 1)
    Initials = Names(0).SubString2(0, 1) & Names(1).SubString2(0, 1)
Else
    If Names(0).Length > 0 Then
        Initials = Names(0).SubString2(0, 1)
    End If
End If
LblFirstLastName.Text = UserName
LblShortName.Text = Initials.ToUpperCase
