Create a VS2010 Addin to collapse every methods of my active document

Question

I'm looking for the source code to collapse every methods of my active document using the VS2010 Addin.
For the moment I parse the text content of the document trying to match if the line is a method signature. If it is the case, I collapse the method.

TextSelection selection = (TextSelection)_applicationObject.ActiveDocument.Selection;
var editPoint = selection.ActivePoint.CreateEditPoint();
editPoint.MoveToLineAndOffset(1, 1);

while (!editPoint.AtEndOfDocument)
{
    editPoint.StartOfLine();
    var line = editPoint.GetText(editPoint.LineLength).TrimStart();

    if (line.StartsWith("public"))
    {
        selection.MoveToLineAndOffset(editPoint.Line, 1);
        _applicationObject.ExecuteCommand("Edit.ToggleOutliningExpansion");
    }

    // go to the next line
}

Does anyone could tell me if I'm on the good way or if there is an easiest way ?

Thanks guys, but i want to use the collapse feature programmatically in a VS Addin. — Nicolas, Nov 16 '11 at 13:41
You can simply trigger the existing commands programmatically. — Andrew Barber, Nov 17 '11 at 03:05

Maybe I asked not so well my question. My real goal was to collapse all the code : properties, methods, comments with ///, using; but not the regions.
Here is one solution :

// reduce everything like Ctrl+M+O
_applicationObject.ExecuteCommand("Edit.CollapsetoDefinitions");

// save the cursor position
TextSelection selection = (TextSelection)_applicationObject.ActiveDocument.Selection;
var selectedLine = selection.ActivePoint.Line;
var selectedColumn = selection.ActivePoint.DisplayColumn;

// open the regions
selection.StartOfDocument();
while (selection.FindText("#region", (int)vsFindOptions.vsFindOptionsMatchInHiddenText))
{
    // do nothing since FindText automatically expands any found #region
}

// put back the cursor at its original position
selection.MoveToDisplayColumn(selectedLine, selectedColumn);

I hope this could help
