Hi,
Here is a sample code should work for the postgis layers as
well:
private void DumpResults(layerObj layer)
{
resultCacheMemberObj res;
shapeObj feature;
using (resultCacheObj results = layer.getResults())
{
if (results != null && results.numresults > 0)
{
// extracting the features found
layer.open();
for (int j=0; j < results.numresults; j++)
{
res = results.getResult(j);
feature = layer.getFeature(res.shapeindex,
res.tileindex);
if (feature != null)
{
Trace.WriteLine(layer.name + " (" +
feature.index + ")");
for (int i = 0; i < feature.numvalues;
i++)
{
Trace.WriteLine(layer.getItem(i) + "=" +
feature.getValue(i));
}
}
}
layer.close();
}
}
}
public void QueryByShape(shapeObj shape)
{
if (shape != null)
{
Trace.WriteLine("The query shape is not specified.");
return;
}
try
{
if (shape.type == MS_SHAPE_TYPE.MS_SHAPE_POLYGON)
{
map.queryByShape(shape);
layerObj layer;
for (int i = 0; i < map.numlayers; i++)
{
layer = map.getLayer(i);
if (layer.status != mapscript.MS_OFF)
{
DumpResults(layer);
}
}
}
else
{
Trace.WriteLine("The query shape must be a polygon.");
}
}
catch (Exception e)
{
Trace.WriteLine("QueryByShape error: " + e.Message);
}
}
Best Regards,
Tamas
