C# for Redis

November 27, 2021 · View on GitHub

Choosing a client library

Following two seem to be most used and best supported libraries:

StackExchange.Redis

Recommended : We will use this one (version used here = 2.2.88)
ServiceStack.Redis

Not recommended as this is commercial and will create problem when project scales, thorowing up exceptions for use exceeded: https://servicestack.net/download#free-quotas.

Create a .NET project

Set the .NET version for our project :

dotnet new globaljson --sdk-version 6.0.100

Create a gitignore file
```
dotnet new gitignore
```
Open the .gitignore file and add redis-data dir to it.
Create a new console project
```
dotnet new console -o ConsoleApp
```

Install the redis library to our project

dotnet add ConsoleApp/ConsoleApp.csproj package StackExchange.Redis

Create a solution (if you want to )

dotnet new sln
dotnet sln add ConsoleApp/ConsoleApp.csproj

Connect with Redis

Create following class in ConsleApp/Program.cs

using System;
using System.Threading.Tasks;
using StackExchange.Redis;

namespace ConsoleApp
{
  public class Program
  {
    public static async Task Main()
    {
      // Configuration for Redis
      var redisConfig = new ConfigurationOptions{EndPoints = { "localhost:6379"}};
      
      // Create connection with Redis
      var redis =  await ConnectionMultiplexer.ConnectAsync(redisConfig);
      var db = redis.GetDatabase();
      
      // Ping redis and check latency
      var pingResult = await db.PingAsync();
      Console.WriteLine($"Redis latency : {pingResult.TotalMilliseconds}ms");
    }
  }
}

If Redis is running, you will see output like :

Redis latency : 2.3453ms
