Get products

An example of getting the features and products of a product line using the extension API.

public void OutputFeatureAndProducts(ICommandContext c, ICommandParams p) 
{ 
var project = c.App.Workspace.CurrentProject; 

//Check that the project is a target for product line development. 
if (!project.IsProductLineSupported) { 
c.App.Output.WriteLine("sample", "This project has not started product line development."); 
return; 
} 

//Get features under the feature model. 
IFeatureModelCollection featureModels = project.ProductLineModel.FeatureModels; 
foreach (IFeatureModel featureModel in featureModels) 
{ 
//Output the feature model name. 
c.App.Output.WriteLine("sample", $"Feature model: {featureModel.Name}"); 
foreach (IFeature rootFeature in featureModel.RootFeatures) 
{ 
//Output the feature name and feature type of the first level. 
c.App.Output.WriteLine("sample", $" Root feature: {rootFeature.Name} (Kind: {rootFeature.VariationKind})"); 
foreach (IFeature subFeature in rootFeature.SubFeatures) 
{ 
//Outputs the feature name and feature type of the second level. 
c.App.Output.WriteLine("sample", $" Sub feature: {subFeature.Name} (Kind: {subFeature.VariationKind})"); 
//In this sample, only the second level is retrieved by default, 
//The third level and below can also be retrieved using the subFeature.SubFeatures property. 
//By using recursive calls, you can retrieve all the features down to the end of the tree, regardless of the depth of the tree. 
} 
} 
} 

//Get products and features for each product 
IConfigurationModel configurationModel = project.ProductLineModel.ConfigurationModel; 
foreach (IProduct product in configurationModel.AllProducts) 
{ 
//Output product name 
c.App.Output.WriteLine("sample", $"Product: {product.Name}"); 
foreach (IFeature selectedFeature in product.SelectedFeatures) 
{ 
//Output feature name for each product (feature name selected in product) 
c.App.Output.WriteLine("sample", $" Selected feature: {selectedFeature.Name}"); 
} 
}
