You have to do the following:<br>
1) Query the featuresource<br>
2) Read the geometry from the response<br>
3) Extract the coordinates<br>
<br>
Item (1) is done with the MgFeatureService.SelectFeatures:<br>
<a class="moz-txt-link-freetext" href="http://mapguide.osgeo.org/files/mapguide/docs/webapi/d5/d10/class_mg_feature_service_cc4faabfd68e8e891287f62e150e2d0d.htm#cc4faabfd68e8e891287f62e150e2d0d">http://mapguide.osgeo.org/files/mapguide/docs/webapi/d5/d10/class_mg_feature_service_cc4faabfd68e8e891287f62e150e2d0d.htm#cc4faabfd68e8e891287f62e150e2d0d</a><br>
<br>
As you can see, the result is a MgFeatureReader instance:<br>
<a class="moz-txt-link-freetext" href="http://mapguide.osgeo.org/files/mapguide/docs/webapi/d6/ddc/class_mg_feature_reader.htm">http://mapguide.osgeo.org/files/mapguide/docs/webapi/d6/ddc/class_mg_feature_reader.htm</a><br>
<br>
The link has example code that shows how to read the data, and find
find a column with the geometry, which is item (2).<br>
<br>
The MgAgfReaderWrite can transform that geometry column into a
MgGeometry object:<br>
<a class="moz-txt-link-freetext" href="http://mapguide.osgeo.org/files/mapguide/docs/webapi/dd/db3/class_mg_agf_reader_writer.htm">http://mapguide.osgeo.org/files/mapguide/docs/webapi/dd/db3/class_mg_agf_reader_writer.htm</a><br>
<a class="moz-txt-link-freetext" href="http://mapguide.osgeo.org/files/mapguide/docs/webapi/d1/d85/class_mg_geometry.htm">http://mapguide.osgeo.org/files/mapguide/docs/webapi/d1/d85/class_mg_geometry.htm</a><br>
<br>
Depending on your geometry type, you get a MgPoint, MgMultiPoint,
MgLineString, etc. object (hint: GetGeometryType).<br>
You need to decide how to get the x/y from such objects, but usually
you can use GetCentroid():<br>
<a class="moz-txt-link-freetext" href="http://mapguide.osgeo.org/files/mapguide/docs/webapi/dc/d21/class_mg_geometric_entity_3830444d005bbcff7bf4b4644a7a2dfc.htm#3830444d005bbcff7bf4b4644a7a2dfc">http://mapguide.osgeo.org/files/mapguide/docs/webapi/dc/d21/class_mg_geometric_entity_3830444d005bbcff7bf4b4644a7a2dfc.htm#3830444d005bbcff7bf4b4644a7a2dfc</a><br>
<br>
The centroid is the "center" of the object, and thus always a point,
and you have item (3).<br>

Can anyone tell me how to get the x-y coordinate of any object on map
trough query feature without using digitization method?<br>
Any suggestion or help will be appricated.<br clear="all">
