如何：使用反射查询程序集的元数据 (LINQ)

using System.Reflection;
using System.IO;
namespace LINQReflection
{
    class ReflectionHowTO
    {
        static void Main(string[] args)
        {
            Assembly assembly = Assembly.Load("System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken= b77a5c561934e089");
            var pubTypesQuery = from type in assembly.GetTypes()
                        where type.IsPublic
                            from method in type.GetMethods()
                            where method.ReturnType.IsArray == true 
                                || ( method.ReturnType.GetInterface(
                                    typeof(System.Collections.Generic.IEnumerable<>).FullName ) != null
                                && method.ReturnType.FullName != "System.String" )
                            group method.ToString() by type.ToString();

            foreach (var groupOfMethods in pubTypesQuery)
            {
                Console.WriteLine("Type: {0}", groupOfMethods.Key);
                foreach (var method in groupOfMethods)
                {
                    Console.WriteLine("  {0}", method);
                }
            }

            Console.WriteLine("Press any key to exit");
            Console.ReadKey();
        }
    }  
}
