How can i get the geometries of a polygon

[xiaoyunnsongb]

Hello superiors:

        there are several features,  the same area  have  point and line,how can I get the the geometries of the polygon

how can I get the all geometries of  the polygon， can you support the api or function ，thanks very much

Xiaoyunn,

   Are you asking how to find if a geometry is inside (contained) by the polygon? How to convert the polyline that closes into a polygon? How to query the geometries of a map service that intersect the polygon, or what?

Dear Robert Scheitlin:

        Thanks very much.I means find geometries  in a polygon. there is  several featurelayer, point an line or other, in a polygon's area ,maybe  have point and line , I want the all geometries  in the polygon, if I let the featurelayers all show。

thanks again.

Xiaoyunn,

   So it sounds like you want to use a QueryTask to query a map service layer and for the query specify the polygon as the geometry for the query. You would repeat the query on the next layer as each geometry type would be on its own map service layer.
