Is there any API in C# for Zooming selected feature?

Question

I am new to ArcGIS and want to implement the Zoom to Selected Features functionality available in Selection menu option (Selection-> Zoom to Selected Features), using C# API.

Is any API available in C# ?

Answer 1

To implement, I would suggest creating an Add-In (in C#) using ArcObjects API. Below are some helpful links to get you started:

• Building add-ins for ArcGIS for Desktop
• Learning ArcObjects

At the minimum you will need to install Microsoft Visual Studio 2010 Express and ArcObjects .NET 10.1 SDK.

An alternative would be to develop a python Add-In. This option would entail less code, however you may be more limited on available GIS classes/objects.

• What is a Python add-in

As I stated in my comment, a web search should give you some source code to start off with.

Try this one:

void ZoomToSelectedFeature(IFeature feature)
{
    IGeometry geometry = feature.Shape;

    IActiveView activeView = ArcMap.Document.ActiveView;
    activeView.Extent = geometry.Envelope;
}

List<IFeature> GetSelectedFeatures(IFeatureLayer selectedFeature)
{
    IFeatureSelection featureSelection = selectedFeature as IFeatureSelection;
    ISelectionSet selectionSet = featureSelection.SelectionSet;
    ICursor cursor ;

    selectionSet.Search(null, false, out cursor);

    IFeatureCursor featureCursor = cursor as IFeatureCursor; 
    IFeature feature = featureCursor.NextFeature();
    List<IFeature> features = new List<IFeature>();
    while (feature != null)
    {
        features.Add(feature);  
        feature = featureCursor.NextFeature();
    }
    return features;
}
