vb.net – how can I remove first characters of a string?

hi,

I got a string and it look like : "test : this is a test. for me."
How can I remove the first charakters? At this example I want to remove the characters "test : ". How can I do this?

I know how to delete from the end, but I realy need it from the beginning :

Dim s As String = Label1.Text
TextBox1.Text = s.Substring(s.Length-9)
