A friend asked me two days ago if I have ever used StackExchange.Redis and asked me for a package class. Since I used ServiceStack.Redis before, since ServiceStack.Redis v4 is a paid version, it is also very popular now. Some companies are using StackExchange.Redis and abandoning ServiceStack.Redis. In fact, I personally think that both drivers are good. However, due to the charging of ServiceStack.Redis, many companies are currently using the V3 version. Some people say that the V3 version has many bugs and has not been maintained or upgraded. But at least so far, I have not found any bugs. .
However, compared with StackExchange.Redis, ServiceStack.Redis has more advantages than StackExchange.Redis regardless of the charges. There are very few documents on StackExchange.Redis, let alone domestic documents. Even the corresponding introductory documents on github are very one-sided. I really think the author of StackExchange.Redis should at least improve the documents. Many of them depend on the source code. There are only examples. There are far fewer examples of using StackExchange.Redis on the Internet than ServiceStack.Redis. It’s not that no one uses it, but I’ve looked it up and found that most of them are encapsulation classes based on String type data. For List, SortedSet, There are very few encapsulation operations in Hash. They are basically written a little east and a little west. It is difficult to find a complete one. After referring to some articles and source code, here is a self-encapsulated class, which basically provides various types of usage encapsulation for everyone to learn and use. If there is anything that is not well written, everyone can also communicate with each other.
ConnectionMultiplexer Encapsulation
The first is the encapsulation of ConnectionMultiplexer. The ConnectionMultiplexer object is the most central object of StackExchange.Redis. Instances of this class need to be shared and reused by the entire application domain, so there is no need to constantly create instances of this object in each operation. Generally, a singleton is used to create and store this object. This is also available on the official website illustrate.

CustomKey is used to represent the system prefix. The AddSysCustomKey method adds a prefix to each key. It is recommended that you name the redis key here. It is best to add a prefix and use: to separate the prefix. It is easier to distinguish when viewing it with a visual tool. For example, my prefix is Demo:test: (usually system name: business name:), and then you When you check it, you will find that it is neat and easy to distinguish a lot of

Let’s talk about the storage of objects in StackExchange.Redis It does not come with serialization and deserialization methods, so I use JsonConvert in ConvertJson and ConvertObj. If you need to change to other serialization and deserialization, just modify these two aspects directly. In addition, , StackExchange.Redis provides asynchronous methods compared to ServiceStack.Redis, so asynchronous and synchronous methods are also encapsulated here.

The above is a general encapsulation of the basic operations of StackExchange.Redis, which is provided for everyone to learn from. If there is anything wrong, I hope we can communicate together.
Question:
StackExchange.Redis does not provide Redis distributed lock operations? ServiceStack.Redis provides the AcquireLock method to operate. Only the LockTake method is found in the StackExchange.Redis source code, and no other methods are found. If anyone has used it, I hope it can be provided.
For more detailed information on StackExchange.Redis universal encapsulation class sharing related articles, please pay attention to the PHP Chinese website!
