how to find the number of occurrences of a substring within a string vb.net

Question

I have a string (for example: \"Hello there. My name is John. I work very hard. Hello there!\") and I am trying to find the number of occurrences of the string

Answer 1

I know this thread is really old, but I got another solution too:

Function countOccurencesOf(needle As String, s As String)
    Dim count As Integer = 0
    For i As Integer = 0 to s.Length - 1
        If s.Substring(i).Startswith(needle) Then
            count = count + 1
        End If
    Next
    Return count
End Function
