Get all features

To get all features, first access the ProductLineModel.FeatureModels property of the IProject object to get all feature models. For each feature model, use the AllFeatures property of the IFeatureModel object to get all child elements.

public void GetAllFeatures(ICommandContext c, ICommandParams p) 
{ 
IFeatureModelCollection featureModels = c.App.Workspace.CurrentProject.ProductLineModel.FeatureModels; 
var features = featureModels.SelectMany(m => m.AllFeatures); 

//Exclude feature groups and get features with non-zero assigned models 
var assignedFeatures = features.Where(f => f.ClassName != "FeatureGroup" && f.GetAssignedModels().Count() != 0); 

//Output 
foreach (IFeature feature in assignedFeatures) 
{ 
//Enumerate and output the model names to which the feature is assigned 
var modelNames = string.Join(",", feature.GetAssignedModels().Select(f => f.Name)); 
c.App.Output.WriteLine("sample", $"Feature Name: {feature.Name}, Kind: {feature.VariationKind}, Assigned Models: {modelNames}"); 
} 
}
