Hello! I am going to make some assumptions. Please correct me if I'm wrong.

Since you are posting on the Network Analyst forum, I will assume that you want to get one of the NAClasses out of an NALayer. For example, you want to open a Closest Facility layer and access the Facilities as a feature class.

You already have a layer as an ILayer. Cast your ILayer as an INALayer.

var naLayer = layer as INALayer;

Via the context and NAClasses, get the naclass and cast it as a feature class.

var facilitiesFeatureClass = naLayer.Context.NAClasses.get_ItemByName("Facilities") as

IFeatureClass;Here is a code snippet that also works:

public ESRI.ArcGIS.NetworkAnalyst.INAClass GetNAClass(ESRI.ArcGIS.NetworkAnalyst.INALayer3 nalayer, System.String naClassName)
{
ESRI.ArcGIS.NetworkAnalyst.INAContext naContext = nalayer.Context; ESRI.ArcGIS.NetworkAnalyst.INamedSet namedSet = naContext.NAClasses; ESRI.ArcGIS.NetworkAnalyst.INAClass naClass = namedSet.get_ItemByName(naClassName) as ESRI.ArcGIS.NetworkAnalyst.INAClass; // Dynamic Cast return naClass;
}
