How to access text associated with individual lines in the selected text area of WinForms SyntaxEditor (EditControl)?

string cleanedSQL = "";
if (this.editControl1.SelectedText != "")
{
    // Get the start and end points of the selection
    CoordinatePoint start = this.editControl1.Selection.Top;
    CoordinatePoint end = this.editControl1.Selection.Bottom;
    string lineText = "";
    for (int i=start.VirtualLine; i<=end.VirtualLine; i++)
    {
       // Get the line object
       ILexemLine lexemLine = this.editControl1.GetLine(i);
       // Get the tokens in each line object and append them to get the line text
       foreach (ILexem lexem in lexemLine.LineLexems)
       {
           lineText += lexem.Text;
       }
       // Store each of these line text
       cleanedSQL += lineText + "\n";
       lineText="";
    }
}

Dim cleanedSQL As String = ""
If Me.editControl1.SelectedText <> "" Then
   ' Get the start and end points of the selection
   Dim start As CoordinatePoint = Me.editControl1.Selection.Top
   Dim end As CoordinatePoint = Me.editControl1.Selection.Bottom
   Dim lineText As String = ""
   Dim i As Integer
   For i = start.VirtualLine To i<- 1 Step =end.VirtualLine
       ' Get the line object
       Dim lexemLine As ILexemLine = Me.editControl1.GetLine(i)
       ' Get the tokens in each line object and append them to get the line text
       Dim lexem As ILexem
       For Each lexem In lexemLine.LineLexems
           lineText += lexem.Text
       Next
       ' Store each of these line text
       cleanedSQL += lineText + "\n"
