Course Introduction：The query syntax or method syntax of LINQ should be selected according to the scene. ① Query syntax is suitable for SQL-like expressions, such as multi-step filtering, projection, sorting, multi-table joining, grouping statistics, etc., with clear and intuitive structure; ② The method syntax is more flexible, supports chain calls and dynamic query conditions construction, and is suitable for aggregation functions, asynchronous operations and scenarios where splicing logic is required; ③ Some operations such as Take, Skip, Any, etc. can only use method syntax. The two functions are the same, and the choice mainly depends on personal habits and specific needs. Reasonable mixing of the two can improve the readability and maintenance of the code.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
