如何在c#中反序列化时忽略JSON字符串中的特定字段？

public class MyClass
{
    public string Field1 { get; set; }

    [JsonIgnore]
    public string Field2 { get; set; }

    public string Field3 { get; set; }
}

// 反序列化时会忽略Field2字段
var myObject = JsonConvert.DeserializeObject<MyClass>(jsonString);

public class IgnoreFieldContractResolver : DefaultContractResolver
{
    private readonly string _fieldName;

    public IgnoreFieldContractResolver(string fieldName)
    {
        _fieldName = fieldName;
    }

    protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
    {
        var property = base.CreateProperty(member, memberSerialization);

        if (property.PropertyName == _fieldName)
        {
            property.ShouldSerialize = instance => false;
        }

        return property;
    }
}

// 使用自定义ContractResolver进行反序列化，忽略Field2字段
var settings = new JsonSerializerSettings
{
    ContractResolver = new IgnoreFieldContractResolver("Field2")
};

var myObject = JsonConvert.DeserializeObject<MyClass>(jsonString, settings);
