Behavioral Patterns – Interpreter

Step 3 Suppose the data has been assessed before the executing interpreter operation in the interpreter service class. The Interpreter services class can edit when the interpreter classes under the IAbstractExpression interface class have edited the complete end. It adds the DataAccess function and the default layout data format function here.

Add a few private functions in the interpreter services class, such as AddExpression and LayoutExpression. Developers need to tell the program which one expression must add this operation and then output the response object description.

The interpreter services class can find out the interface has two same seem like function name, such as Expression, Expression2 which because these are on behalf of two different operation methods to explain the executing interpreter pattern concept operation. The first method is to fasten the response class file with the List object in the function block. The second method is that the response class uses the generic skill to explain the response class file with the ICollection object.

Step 4 Add the interpreter pattern-related files in the web project, such as view flies, controller files. Register the interpreter pattern files in the web project’s start.cs file.

// Interpreter
services.AddScoped(typeof(IInterpreter<,>), typeof(InterpreterServices<,>));
