Caching in C# can be implemented using several different techniques, such as using in-memory caching with libraries like memorycache or distributed caching with libraries like redis. Here is an example of how to use in-memory caching with the memorycache library in C#:
- First, install the MemoryCache NuGet package by running the following command in the Package Manager Console:
1
|
Install-Package Microsoft.Extensions.Caching.Memory |
- Next, import the MemoryCache namespace in your C# class:
1
|
using Microsoft.Extensions.Caching.Memory; |
- Create a new instance of MemoryCache in your class:
1 2 3 4 5 |
private IMemoryCache _memoryCache;
public YourClassConstructor(IMemoryCache memoryCache)
{
_memoryCache = memoryCache;
}
|
- Use the MemoryCache instance to store and retrieve cached data:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
// Store data in the cache with a key and a value
_memoryCache.Set("key", "value");
// Retrieve data from the cache using the key
var cachedData = _memoryCache.Get<string>("key");
// Check if the data exists in the cache before retrieving it
if (!_memoryCache.TryGetValue("key", out string cachedData))
{
// Data not found in cache, fetch it from the source
cachedData = FetchDataFromSource();
_memoryCache.Set("key", cachedData);
}

By using caching in C# like this, you can improve the performance of your application by reducing the number of times data needs to be fetched from the source.
