How to manage caching in vb.net?

In Visual Basic .NET, caching can be managed using the System.Runtime.Caching namespace. Here is a basic example of how to manage caching in VB.NET:

1. First, add a reference to the System.Runtime.Caching namespace in your project.
2. Create an instance of the MemoryCache class to start using caching in your application:

1

Dim cache As MemoryCache = MemoryCache.Default

1. Add an item to the cache with a specific key and expiration time:

1
2
3
4
5

Dim cacheItem = "Some cached data"
Dim cachePolicy = New CacheItemPolicy With {
    .AbsoluteExpiration = DateTimeOffset.Now.AddMinutes(10)
}
cache.Add("CacheKey", cacheItem, cachePolicy)

1. Retrieve an item from the cache using its key:

1

Dim cachedData As Object = cache("CacheKey")

1. Remove an item from the cache using its key:

1

cache.Remove("CacheKey")

1. Check if an item exists in the cache before retrieving it:

1
2
3

If cache.Contains("CacheKey") Then
    Dim cachedData As Object = cache("CacheKey")
End If

By using the MemoryCache class and its methods, you can easily manage caching in your VB.NET application. Remember to consider the scalability and performance implications of caching when implementing it in your application.
