[MoCoolKaErpGen代码讲解] WCF knownType 在web.config中生成

MoCoolKaErp只有一个入口，接收参数为基类，按WCF协议必须声明所有的子类为knownType.最直接的办法就是遍历所有assembly，寻找所有的子类。
用linq遍历assembly寻找指定类生成web.config中序列化
linq语法的确精炼，一句话就行了
方法
        public XElement GenConfig(String[] assemblys)
        {

            return new XElement("system.runtime.serialization", new XElement("dataContractSerializer",
                 new XElement("declaredTypes",
                     new XElement("add", new XAttribute("type", typeof(MKEntity).AssemblyQualifiedName),
                         (from ass in assemblys
                          let assembly = Assembly.Load(ass)
                          select from type in assembly.GetTypes()
                                 where (type.IsClass && type.IsSubclassOf(typeof(MKEntity)))
                                 select (new XElement("knownType", new XAttribute("type", type.AssemblyQualifiedName))))
                         ))))
                     ;
        }
        调用
               [TestMethod()]
        public void GenConfigTest()
        {
            MKGenConfig target = new MKGenConfig(); // TODO: Initialize to an appropriate value
            string[] assemblys = new String[] { "MoCoolKaCoreErp", "MoCoolKaErp" };// TODO: Initialize to an appropriate value
            XElement expected = null; // TODO: Initialize to an appropriate value
            XElement actual;
            actual = target.GenConfig(assemblys);
            //Assert.AreEqual(expected, actual);
            //Assert.Inconclusive("Verify the correctness of this test method.");
        }
