The C # cache is primarily designed to increase the speed at which data is read. Because of the traffic bottleneck between the server and the application client, when reading the bulk data, using the cache to directly serve the client can reduce the

1.1 Server back to front endThe returned data is put into the object (as required: a single object, a collection, a key-value pair), and then JSON serialization is returned to the front end. The Json.NET library can be referenced here, or it can be

To create an object instance using configuration files and reflectionIn order to increase the scalability of the program and improve the configuration, it is often necessary to use configuration file + reflection to dynamically invoke the method.The
