arcobjects,判斷對象自相交

Delphi代碼

//判斷對象自相交

function IsSelfCross(PGeoMetry: IGeoMetry): boolean;
var
    pTopo                               : ITopologicalOperator2;
    B                                   : wordbool;
begin
    pTopo := PGeoMetry as ITopologicalOperator2;
    pTopo.Set_IsKnownSimple(False);
    pTopo.Get_IsSimple(B);
    result := B;

end; 

C#代碼

//判斷對象自相交
        public static bool IsSelfCross(IGeometry pGeometry)
        {

             pTopologicalOperator2.IsKnownSimple_2 = false;
             return pTopologicalOperator2.IsSimple;
