How to get "LINE" with "dxfCode" where "endpoint" is the specified value

I know that I can get a line starting at SP by following this code,

new TypedValue((int)DxfCode.Operator, "<and"), new TypedValue((int)DxfCode.Start, "LINE"), new TypedValue((int)DxfCode.Operator, "="), new TypedValue((int)DxfCode.XCoordinate, sP), new TypedValue((int)DxfCode.Operator, "and>"),

I want to know how to get a line that endpoint at SP。thank！

Startpoint of Line dxf code = 10.
Endpoint of Line dxf code = 11.
new TypedValue (11, eP);

Hi,

The most complete documentation about selection filters is the AutoLISP one.

The following filter will select lines which end point X coordinate is equal to sP X coordinate.

var filter = new SelectionFilter(new[] { new TypedValue(0, "LINE"), new TypedValue(-4, "=,*,*"), new TypedValue(11, sP) });
