示例1: GetExports
public void GetExports()
{
using (var directory = CreateTemporaryDirectory())
{
var catalog = new AggregateCatalog();
Expression<Func<ExportDefinition, bool>> constraint = (ExportDefinition exportDefinition) => exportDefinition.ContractName == AttributedModelServices.GetContractName(typeof(MyExport));
IEnumerable<Tuple2<ComposablePartDefinition, ExportDefinition>> matchingExports = null;
matchingExports = catalog.GetExports(constraint);
Assert.IsNotNull(matchingExports);
Assert.IsTrue(matchingExports.Count() == 0);
var testsDirectoryCatalog = new DirectoryCatalog(directory.DirectoryPath);
catalog.Catalogs.Add(testsDirectoryCatalog);
matchingExports = catalog.GetExports(constraint);
Assert.IsNotNull(matchingExports);
Assert.IsTrue(matchingExports.Count() >= 0);
IEnumerable<Tuple2<ComposablePartDefinition, ExportDefinition>> expectedMatchingExports = catalog.Parts
.SelectMany(part => part.ExportDefinitions, (part, export) => new Tuple2<ComposablePartDefinition, ExportDefinition>(part, export))
