how to use selectionset in C#

Anonymous — Tue, 24 Mar 2009 23:08:46 GMT

Hi, I've done this in VB and it worked, but now the same code in C# and it is not working. please help!
basically, I want to select objects using selectionsets.add:

AcadDocument m_ACADDoc;
......

double []corner1 = new double [3];
double []corner2 = new double [3];
corner1[0] = -100;
corner1[1] = -100;
corner1[2] = 0;
corner2[0] = 100;
corner2[1] = 100;
corner2[2] = 0;

AcadSelectionSet oAcadSSet = m_ACADDoc.SelectionSets.Add("SSET");
object ref_missing = Type.Missing;
oAcadSSet.Select(AcSelect.acSelectionSetCrossing, corner1, corner2, ref_missing, ref_missing);

however, the returned set (oAcadSSet) always contains 0 object.

even if i tried the following (which is copied from internet):
object gpCode = new short[] { 0 };
object dataValue = new object[] { "LINE" };
object groupCode = gpCode;
object DataCode = dataValue;
oAcadSSet.Select(AcSelect.acSelectionSetCrossing, corner1, corner2, groupCode, DataCode);

the set still doesn't contain any object.

Do anyone know how to fix this? thanks!

Did you run your working VB version through a
converter such as the one found in CSharpDevelop
href="http://www.icsharpcode.net/OpenSource/SD/">http://www.icsharpcode.net/OpenSource/SD/ or
did you hand convert it?

If you didn't use a converter, try that and see
what errors and/or warnings there are and work from there or post your VB
version here or you're welcome to email me directly.

this is the vb code which works well:

Dim pCorner1(0 to 2) as double

Dim pCorner2(0 to 2) as double

pCorner1[0] = 0

pCorner1[1] = 0

pCorner1[2] = 0

pCorner2[0] = 10

pCorner2[1] = 10

pCorner2[2] = 0

Dim ssetObj As AcadSelectionSet

ssetObj.Select mode, pCorner1, pCorner2

In C#, where you do not want to supply an optional parameter, you supply the
constant 'System.Type.Missing'.

Since the SelectCrossingWindow method
is overloaded use the version with just the corner parameters. No need for
optional parameters.

Thanks, Tony.
the System.Type.Missing is what I used in my first post. it compiled but the function didn't return any valid objects.
