Managing Multiple Tutoring Sessions with DeepSeek in C#

Welcome to the next step in your journey of creating a personal tutor with DeepSeek! In the previous lessons, you learned how to send queries to DeepSeek's language model, explored model parameters, maintained tutoring session history, and personalized AI behavior with system prompts. Now, we will focus on managing multiple tutoring sessions. This is crucial for applications where you need to handle several educational interactions simultaneously, such as a tutoring platform serving multiple students. By the end of this lesson, you will be able to create and manage multiple tutoring sessions using DeepSeek's API in C#, setting the stage for more complex educational interactions.

In a tutoring application, each educational interaction should be treated as a separate session. To achieve this, we use unique identifiers for each tutoring session. This ensures that queries and explanations are correctly associated with their respective sessions. In C#, we use Guid.NewGuid().ToString() to generate a unique identifier for each tutoring session. When a new tutoring session is created, a unique sessionId is generated, and an empty history is initialized.

We store tutoring history in a dictionary called tutoringSessions, where each key is a unique sessionId and the value is a list of messages representing the conversation history. When a new session is created, we also add a system prompt to the session's history to define the tutor's behavior.

using System;
using System.Collections.Generic;

// Define a message structure
public class Message
{
    required public string Role { get; set; }
    required public string Content { get; set; }
}

// Store all active tutoring sessions
private static Dictionary<string, List<Message>> tutoringSessions = new Dictionary<string, List<Message>>();

// Define a common system prompt for all sessions
private static Message systemPrompt = new Message
{
    Role = "system",
    Content = "You are a knowledgeable and patient tutor, ready to assist with various academic subjects."
};

// Create a new tutoring session with a unique identifier
public static string CreateSession()
{
    string sessionId = Guid.NewGuid().ToString(); // Create unique session identifier
    tutoringSessions[sessionId] = new List<Message>();
    tutoringSessions[sessionId].Add(systemPrompt); // Add system prompt to tutoring history
    return sessionId;
}

This approach ensures that each tutoring session is uniquely identified and maintains its own conversation history, allowing for distinct and coherent educational interactions.
