Welcome back to our Redis course! Now that you know how to connect to a Redis server, it's time to move forward and explore how to work with numbers in Redis. This unit builds on our previous lesson, so make sure you're comfortable with establishing a connection to a Redis server.

In this lesson, you will learn how to:

1. Set numeric values in Redis using C#.
2. Retrieve and process numeric values in C#, handling the relevant data types.

Here's the code snippet that we'll be working with:

Let's break down the code:

• As in the previous lesson, we first establish a connection to the Redis server using the ConnectionMultiplexer class from the StackExchange.Redis library.
• We use the StringSet method to store the numeric values: count with a value of 5 and completion_rate with a value of 95.5.
• We retrieve these values using the StringGet method. Unlike some weaker type systems, in C#, you can cast directly to the appropriate numeric types, such as int and double, after fetching them, as needed.

Working with numbers in Redis is crucial because many real-world applications involve numeric data. From tracking user statistics to monitoring system performance, managing numbers in Redis allows you to perform a variety of useful operations efficiently. By mastering these basic operations with numbers, you'll be well-prepared to tackle more complex tasks and optimize your applications.
