Serialization Performance

LHZ.FastJson has been re-architected with a highly optimized serialization engine. The table below compares serialization performance across LHZ.FastJson, Newtonsoft.Json, and System.Text.Json:

BenchmarkDotNet=v0.13.1, OS=Windows 10.0.19044.1706 (21H2)
Intel Core i7-9700K CPU 3.60GHz (Coffee Lake), 1 CPU, 8 logical and 8 physical cores

Usage

Serialization with LHZ.FastJson

Example
Student student = new Student
{
    NO = 1,
    [JsonProperty("studentName")]
    Name = "lhz",
    Age = 18,
    Brithday = new DateTime(2002, 1, 1)
};

string jsonStr = LHZ.FastJson.JsonConvert.Serialize(student);

Console.WriteLine(jsonStr);
Output
PS C:\Users\admin\source\repos\LHZ.FastJson\LHZ.FastJson.Test> dotnet run
{"NO":1,"studentName":"lhz","Age":18,"Brithday":"2000/1/1 0:00:00"}

Deserialization with LHZ.FastJson

Example
string str = "{\"NO\":1,\"studentName\":\"lhz\",\"Age\":18,\"Brithday\":\"2000/1/1 0:00:00\"}";

Student student = JsonConvert.Deserialize<Student>(str);

Console.WriteLine("NO:{0},Name:{1},Age:{2},Brithday:{3}", student.NO, student.Name, student.Age, student.Brithday.ToString("yyyy-MM-dd"));
Output
PS C:\Users\admin\source\repos\LHZ.FastJson\LHZ.FastJson.Test> dotnet run
NO:1,Name:lhz,Age:18,Brithday:2000-1-1
