C# 序列化与反序列化

1. 通过 JsonSerializer 类的 Serialize/Deserialize 函数，示例代码如下：

#region 序列化测试
RegAccessInfo testInfo = new RegAccessInfo();
testInfo.DeviceId = "dev01";
testInfo.RegAddr = 0xC0;
testInfo.RegData = 0x2018;

string jsonString = JsonSerializer.Serialize(testInfo);
RegAccessInfo testInfo2 = JsonSerializer.Deserialize<RegAccessInfo>(jsonString);

byte[] jsonUtf8Bytes = JsonSerializer.SerializeToUtf8Bytes(testInfo);
var readOnlySpan = new ReadOnlySpan<byte>(jsonUtf8Bytes);
RegAccessInfo testInfo3 = JsonSerializer.Deserialize<RegAccessInfo>(readOnlySpan);

Console.WriteLine("Test end.");
