Newtonsoft JSON Schema忽略用于反序列化的验证 [英] Newtonsoft JSON Schema Ignore Validations For Deserialize

问题描述

我有以下JSON&课

I have following JSON & class,

{ "Id":123， "FirstName":"fName"， "LastName":"lName" }

{ "Id": 123, "FirstName": "fName", "LastName": "lName" }

public class Student
{
    public int Id { get; set; }

    [StringLength(4)]
    public string FirstName { get; set; }

    [StringLength(4)]
    public string LastName { get; set; }
} 

我正在尝试在JSON之上反序列化以创建学生类的实例.

I'm trying to deserialize above JSON to create an instance of student class.

var body = //above json as string;

Student model = null;

JSchemaGenerator generator = new JSchemaGenerator();
JSchema schema = generator.Generate(typeof(Student));

using (JsonTextReader reader = new JsonTextReader(new StringReader(body)))
{
    using (JSchemaValidatingReader validatingReader = new JSchemaValidatingReader(reader) { Schema = schema })
    {
        JsonSerializer serializer = new JsonSerializer();
        model = serializer.Deserialize(validatingReader, typeof(Student));
    }
}

这将引发字符串长度验证异常，是否有任何方法可以通过忽略所有数据注释验证来反序列化JSON?

This is throwing an exception for string length validation, is there any way to deserialize the JSON by ignoring all data annotation validations?

推荐答案

您可以使用以下代码反序列化数据.由于序列错误，您正在序列化之前进行验证.

You can deserialize your data using the below code. You are validating before serializing due to which it is throwing error.

 var body ="{\"Id\":123,\"FirstName\":\"fNamesdcsdc\",\"LastName\":\"lName\"}";
            using (JsonTextReader reader = new JsonTextReader(new StringReader(body)))
            {
                JsonSerializer serializer = new JsonSerializer();
                var model = serializer.Deserialize(reader, typeof(Student));
            }
