Code Create a built-in method without a method name and associate the Code with the delegated instance. This makes the delegation instantiation more intuitive and convenient, and improves the readability and maintainability of the Code. The following describes how to use a simple anonymous method:

First of all, I generally rarely use the Dynamic keyword (class), because after all, is implemented by reflection, so for performance is still a lot of disadvantage ( Note: Because the heart is not the bottom, check some information that dynamic does not seem to be realized by reflection, and its performance is much higher than the direct reflection , as for why, I do not understand, I hope you know the message can tell me a bit! Thank you ^_^) I do not know why the DLR can achieve the same impl
An anonymous type is a class type consisting of one or more public read-only attributes. Class Members (such as methods or events) of other classes are not allowed ). The anonymous type cannot be forcibly converted to any interface or type except the object.
The anonymous type is created using the new operator and the initial value setting.
