Json.NET的JsonProperty的Converter和MemberConverter属性的区别

Json.NET是一个广泛使用的.NET库，用于在.NET应用程序中处理JSON数据。在Json.NET中，JsonProperty是一个属性，用于指定Json序列化和反序列化期间应该如何处理属性。JsonProperty属性有两个重要的属性：Converter和MemberConverter。本文将介绍这两个属性的区别，并提供相应的案例代码。

csharp
public class Person
{
    public string Name { get; set; }
    
    [JsonProperty(PropertyName = "birthDate")]
    [JsonConverter(typeof(CustomDateTimeConverter))]
    public DateTime BirthDate { get; set; }
}
public class CustomDateTimeConverter : JsonConverter
{
    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        DateTime date = (DateTime)value;
        writer.WriteValue(date.ToString("yyyy-MM-dd"));
    }
    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        string dateString = (string)reader.Value;
        return DateTime.ParseExact(dateString, "yyyy-MM-dd", CultureInfo.InvariantCulture);
    }
    public override bool CanConvert(Type objectType)
    {
        return objectType == typeof(DateTime);
    }
}

csharp
public class Person
{
    public string Name { get; set; }
    
    [JsonProperty(PropertyName = "birthDate")]
    public DateTime BirthDate { get; set; }
    
    [JsonProperty(PropertyName = "age")]
    [JsonConverter(typeof(CustomAgeConverter))]
    public int Age { get; set; }
}
public class CustomAgeConverter : JsonConverter
{
    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        int age = (int)value;
        writer.WriteValue(age.ToString());
    }
    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        int age = (int)reader.Value;
        return age;
    }
    public override bool CanConvert(Type objectType)
    {
        return objectType == typeof(int);
    }
}
