MessagePack 和System.Text.Json 序列化和反序列化性能及对比分析（message in a bottle）快来看

文章摘要

这篇文章展示了如何使用 `BenchmarkDotNet` 属性在公共类 `SerializeTest` 中进行性能测试。通过 `MessagePack` 和 `Json` 对一组 `TestModule` 实例进行编码和解码，文章比较了这两种编码方式的性能差异。`TestModule` 类包含多个属性，主要用于测试不同数据结构或字段的处理能力。文章的核心内容是通过性能测试评估编码和解码的不同方法。

{
var d=new TestModule(Guid.NewGuid(), Guid.NewGuid().ToString(“N”) + i);
d.i=i;
TestDatas.Add(d);
}

Pack=MessagePackSerializer.Serialize(TestDatas, MessagePack.Resolvers.ContractlessStandardResolver.Options);
Json=JsonSerializer.SerializeToUtf8Bytes(TestDatas);
