TypeQuery¶

Find types in a compilation or namespace.

See also: Queries Overview | MethodQuery | PropertyQuery

// From a compilation
var types = TypeQuery.From(compilation)
    .ThatArePublic()
    .ThatAreClasses()
    .WithAttribute("MyAttribute")
    .GetAll();

// From a namespace symbol
var types = TypeQuery.From(namespaceSymbol)
    .ThatAreInterfaces()
    .InNamespaceStartingWith("MyApp.Domain")
    .GetAll();

// Using extension method
var types = compilation.QueryTypes()
    .ThatAreRecords()
    .GetAll();
