Interpreter pattern is used to defines a grammatical representation for a language and provides an interpreter to deal with this grammar. In this article, I am going to discuss the Interpreter Design Pattern in C# with examples.Please read our previous article where we discussed the Strategy Design Pattern in C# with real-time examples. objExpressions.Add(new SeparatorExpression());In this article, I am going to discuss the.The Interpreter Design Pattern Provides a way to evaluate language grammar or expression. What the interpreter will do is, it will convert the context value into the date expression format you passed to it.

So, basically the interpreter contains the logic or grammar to convert the context object into a specific readable format.In order to understand the class diagram, please have a look at the following image.Let us implement the example that we discussed here step by step using the Interpreter Design Pattern in C#.
This pattern involves implementing an expression interface which tells to interpret a particular context. Each class implements the Evaluate method according to its own grammar.Create a class file with the name DayExpression and then copy and paste the following code.
This context object holds the value that we want to interpret.These are going to be the concrete classes that implement the AbstractExpression interface. As you can see in the following image, we define a class for each type of grammar such as Month, Year, Day, and separator. This type of pattern comes under behavioral pattern.
