Select offset/range within a line in .cs Document

Question

I am writing some unit test method to check some functionality after user selects a particular characters within the .cs file/.

So for this, I have created dte object & set its Active Document to my abc.cs file & want to programmatically select a few characters within a line in that abc.cs file.

((TextSelection)m_testHelper.Dte2.ActiveDocument.Selection).GotoLine(46,true);

This allows to select the whole line(no. 46 in abc .cs file). But I want the text in quotes to be set for Selection as below shown in abc .cs file at Line no. 46

private const string HeartBeatFileName = "abc.exe.heartbeat";

Also tried:

((TextSelection)m_testHelper.Dte2.ActiveDocument.Selection).MoveToLineAndOffset(46, 50, true);

But nt working as expected. Am I doing something wrong??

You need first to move to the initial point without extending the selection and then to move to the final point extending the selection. This sample selects the characters 5 to 10 of the first line of the active document:

EnvDTE.TextSelection textSelection;

textSelection = (EnvDTE.TextSelection) _dte.ActiveDocument.Selection;

textSelection.MoveToLineAndOffset(1, 5, false);
textSelection.MoveToLineAndOffset(1, 10, true);
