Finding in layer

Question

(arcgis engine in vs 2005 + c#)
I have axMapControl with document .mxd, wich has several groupped layers. And try to make searching in layer elements with certain value of attribute. Now I try use next code:            ESRI.ArcGIS.esriSystem.IArray pArray;
            ESRI.ArcGIS.Carto.IFind pfind;
            ESRI.ArcGIS.Carto.IFeatureLayer layer;
            layer = (ESRI.ArcGIS.Carto.IFeatureLayer)axMapControl1.get_Layer(6) as ESRI.ArcGIS.Carto.IFeatureLayer;
            pfind = (ESRI.ArcGIS.Carto.IFind)layer;
            pArray = pfind.Find("???????", true, pfind.FindFields, axMapControl1.ActiveView.ScreenDisplay.CancelTracker);
            int i = pArray.Count;

But needed layer included in some group.
Did anybody help me - how i can get access to layer of certain group?
Thanks for any help or reference

I get the field, wich contain the value of shape type            ESRI.ArcGIS.Geodatabase.IQueryFilter qf = new ESRI.ArcGIS.Geodatabase.QueryFilterClass();
            qf.WhereClause = "Номе�? = 2";

ESRI.ArcGIS.Geodatabase.IFeatureCursor featureCursor = layer.FeatureClass.Search(qf, false);
            ESRI.ArcGIS.Geodatabase.IFeature feature = featureCursor.NextFeature();
            ESRI.ArcGIS.Geometry.IGeometry shape = feature.Shape as ESRI.ArcGIS.Geometry.IGeometry;

And now the question is - how get coordinate of the shape value?
I think, that shape must be converted to IArea value and the I will use QueryCentroid or QueryLabelPoint method

Thanks!

Hi,
and 
1. how I can get some fiels from result of type ESRI.ArcGIS.Geodatabase.ISelectionSet
2. can't I use somethink like that1. У ва�?его IFeatureLayer пол�?�?ае�?е IFeatureClass
2. У IFeatureClass в�?полняе�?е Select п�?едва�?и�?ел�?но создав IQueryFilter и записав �?�?да �?е�?ез ме�?од WhereClause �?�?о-�?о �?ипа [Field_Name] Like "�?�?яжа"
3. �? �?ез�?л�?�?а�?е в�?полнения ме�?ода Select возв�?а�?ае�?ся IFeatureCursor
4. У IFeatureCursor в�?з�?ваем ме�?од NextFeature ко�?о�?�?й возв�?а�?ае�? IFeature
5. У IFeature зап�?а�?иваем геоме�?�?и�? �?е�?ез свойс�?во Shape - возв�?а�?ае�? IGeometry (для зап�?оса зна�?ений а�?�?иб�?�?ов испол�?з�?ем свойс�?во Value, ко�?о�?ое возв�?а�?ае�? VARIANT)
6. �?�?еоб�?аз�?ем IGeometry к �?ип�? IArea и в�?зовем ме�?од QueryCentroid или QueryLabelPoint в зависимос�?и о�? �?ого �?�?о в�? �?о�?и�?е пол�?�?и�?�?.

The goal is to get coordinates of the center of the shapeType field.
Thanks for any advice or reference!

Hi,

Either you have to specify workspace if that one is available with you...or make it null.

Something like this....

ESRI.ArcGIS.Geodatabase.IQueryFilter qf = new ESRI.ArcGIS.Geodatabase.QueryFilterClass();
            qf.WhereClause = "Name='moscow'";
            layer.FeatureClass.Select(qf, ESRI.ArcGIS.Geodatabase.esriSelectionType.esriSelectionTypeIDSet,
                ESRI.ArcGIS.Geodatabase.esriSelectionOption.esriSelectionOptionNormal, null);

Thanks and Regards
