почти так же, как у Дарина, но вот, пожалуйста.
public static List<Type> FindAllDerivedTypes<T>()
{
return FindAllDerivedTypes<T>(Assembly.GetAssembly(typeof(T)));
}
public static List<Type> FindAllDerivedTypes<T>(Assembly assembly)
{
var derivedType = typeof(T);
return assembly
.GetTypes()
.Where(t =>
t != derivedType &&
derivedType.IsAssignableFrom(t)
).ToList();
}
используется как:
var output = FindAllDerivedTypes<System.IO.Stream>();
foreach (var type in output)
{
Console.WriteLine(type.Name);
}
выходы:
NullStream
SyncStream
__ConsoleStream
BufferedStream
FileStream
MemoryStream
UnmanagedMemoryStream
PinnedBufferMemoryStream
UnmanagedMemoryStreamWrapper
IsolatedStorageFileStream
CryptoStream
TailStream
