I am iterating through the table rows . if the row row is null I just want to remove the row. it shows an error

 Public Sub RemoveBlankRow(ByVal MyDataTable As DataTable)
        Try
            Dim MyRowStr As String = String.Empty
            For Each MyRow As DataRow In MyDataTable.Rows
                MyRowStr = ""
                For Each MyCellText As Object In MyRow.ItemArray
                    MyRowStr = MyRowStr + MyCellText.ToString
                Next
                MyRowStr = Replace(MyRowStr, "0", " ")
                MyRowStr = Replace(MyRowStr, ".", " ")
                If MyRowStr.Trim = String.Empty Then
                    MyDataTable.Rows.Remove(MyRow)
                End If
            Next
        Catch ex As Exception

        End Try
    End Sub

How to overcome this issue?
