                        Dim expr As New System.Text.RegularExpressions.Regex(pattern)
                        Dim m As System.Text.RegularExpressions.MatchCollection

Try do use StreamReader class to read the file line by line, and count repetitions of char:

Dim counter As Integer = 0
Using sr As New StreamReader("filePath")
	Dim line As String
	Dim data As String() = Nothing
	While (InlineAssignHelper(line, sr.ReadLine())) IsNot Nothing
		If line.Contains("*"C) Then
			data = line.Split(New Char() {"*"C}, StringSplitOptions.None)
			counter += data.Length - 1
		End If
	End While
End Using
MessageBox.Show("char * was counted: " & counter & " times")
