Readline to start at specific Row,Column

How can I get Streamreader to read file to specific row/column? For example:

I want this to insert read txt file starting at second row and second column.

Code:

 Using sr As New StreamReader(File.Open(FileNameOnly, FileMode.Open))

                    Try

                        Dim g As DataGridView = MyActiveSheet.Grid

                        ClearRows()



                        Dim TextLine As String = ""

                        Dim SplitLine() As String

                        Do While sr.Peek() <> -1

                            TextLine = sr.ReadLine()

                            SplitLine = Split(TextLine, ";")

                            g.Rows.Add(SplitLine)

                        Loop



                    Catch ex As EndOfStreamException

                        'Catch any errors because file is incomplete

                    End Try

                End Using
