Shown is a usage example for writing data generated programmatically using LINQ.

The sources are here.

Here we create a sequence of several objects of an anonymous type, which we write to ZooKeeper, then read the json file.

         // Create a query sequence
         Random rnd = new Random();
         string[] names = ["order", "subrequest", "surprise", "image"];
         string[] statuses = ["done", "pending", "running"];
         var query = Enumerable.Range(0, 4).Select(i => new
         {
             pos = i,
             name = names[rnd.Next(0, names.Length)],
             longValue = rnd.NextInt64(),
             doubleValue = rnd.NextDouble(),
             status = statuses[rnd.Next(0, statuses.Length)],
             watched = rnd.Next(0, 2) == 0,
             timestamp = new DateTime(rnd.NextInt64(DateTime.MinValue.Ticks, DateTime.MaxValue.Ticks)),
         });
         // Ready
        
         // Connect with the keeper
         ...
         // Eat

         ZkJsonSerializer zkJson = new()
         {
             ZooKeeper = zk,
         };
         JsonSerializerOptions options = new()
         {
             WriteIndented = true,
         };
         options.Converters.Add(zkJson);
 
         // Serialize the sequence into a JsonElement, and deserialize it into a keeper

         JsonSerializer.Deserialize<ZkStub>(JsonSerializer.SerializeToElement(query, options), options);

         // Reset the factory

         zkJson.Reset();

         // Read from keeper

         MemoryStream ms = new();
         JsonSerializer.Serialize(ms, ZkStub.Instance, options);
         ms.Flush();
         ms.Position = 0;


         Console.WriteLine(new StreamReader(ms).ReadToEnd());

    

Something has appeared in the keeper!
