Quit Memcached in C# (Detailed Guide w/ Code Examples)

Use Case(s)

The quit command in Memcached is used to close the connection to the Memcached server. This is commonly useful when you're done with your cache operations and want to free up resources, or when your application is about to stop, and you need to ensure all connections are properly closed.

Code Examples

In C#, you typically use a library like EnyimMemcached to interact with Memcached. However, this library manages connections for you and there isn't a direct equivalent to the quit command. When you're done with an IMemcachedClient instance, you dispose of it and the underlying connection will be closed.

using Enyim.Caching; using Enyim.Caching.Memcached; using(var client = new MemcachedClient()){ // perform operations } // connection is closed here

Inside the using statement you put all of your caching operations. Once the execution leaves the using block, the client is automatically disposed, closing the connection.

Best Practices

  • Always remember to dispose of MemcachedClient instances when you're done using them. This returns the connection to the pool so that it can be reused later.
  • You can also use dependency injection (in conjunction with the IDisposable interface) to manage MemcachedClient lifetimes more effectively.

Common Mistakes

  • Forgetting to dispose of MemcachedClient instances after use, which could lead to resource leaks.
  • Creating a new MemcachedClient for each operation. This is unnecessary and inefficient as the client is designed to be reused.


Q: Do I need to explicitly quit a connection to Memcached in C#?

A: No, you don't have to manually quit the connection. In C#, when you are done with an instance of MemcachedClient, you dispose it and the underlying connection will be closed automatically.

Q: Can I reuse a MemcachedClient after disposing of it?

A: No, once a MemcachedClient is disposed, you cannot reuse it. You should create a new instance if you need to connect to Memcached again.
