Demonstrate Redis with WinForms

This section covers C# WinForms Redis cache wrapper based on StackExchange.Redis

Open Visual Studio, create a WinForms project, then install dependency packages via NuGet

Install Dependencies

1. StackExchange.Redis
   The most‑popular open‑source Redis client in the .NET ecosystem for communicating with Redis server.
   Github Repository：https://github.com/StackExchange/StackExchange/StackExchange.Redis
   Redis exposes TCP protocol. In theory you could write raw Socket code, but mature third‑party libraries are almost always used in production development.
2. Newtonsoft.Json（Json.NET）
   Handles object serialization: converts arbitrary objects into JSON strings then byte arrays for Redis storage; deserializes data on readback.
   Must be installed from NuGet. The code JsonConvert.SerializeObject comes from this library.

Redis Wrapper Methods

// Write cache: store object with expiration in minutes
private bool Set(string key, object data, int cacheTime)
{
    if (data == null)
    {
        return false;
    }
    var entryBytes = Serialize(data);
    var expiresIn = TimeSpan.FromMinutes(cacheTime);
    return db.StringSet(key, entryBytes, expiresIn);
}

// Object serialization: entity object → UTF8 byte array
private byte[] Serialize(object data)
{
    var json = JsonConvert.SerializeObject(data);
    return Encoding.UTF8.GetBytes(json);
}Code language: PHP (php)
