Reflection definition: the ability to review metadata and collect information about its type. Metadata (the most basic data unit after compilation) is a lot of tables. When compiling an assembly or module, the compiler creates a class definition

  Preface  Two methods for obtaining information about a method   Reflection is a C # function that allows users to obtain class information. The Type object maps to the underlying object; In. Net, once the Type object is obtained, you can use the

We know two parallel programming models: message-based and shared memory-based. Some time ago, the project encountered the second problem of using multithreading to develop parallel programs to share resources. Today, we will proceed with the actual

For a collection class that implements Foreach traversal, you must implement the IEnumerable interface. For a generic set, you must implement the IEnumerable interface. ListForeach : IEnumerable T:, index = ListForeach (= (index >== T [array.
