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

[cj4HG5A]

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)
});
