如何使用C#比较两个Json对象 [英] How to compare two Json objects using C#

问题描述

我有两个Json对象，如下所示.我正在使用Newtonsoft库进行Json解析.

I have two Json objects as below need to be compared. I am using Newtonsoft libraries for Json parsing.

string InstanceExpected = jsonExpected;
string InstanceActual = jsonActual;
var InstanceObjExpected = JObject.Parse(InstanceExpected);
var InstanceObjActual = JObject.Parse(InstanceActual);

我正在使用Fluent Assertions进行比较.但是问题是只有当属性计数/名称不匹配时，Fluent断言才会失败.如果json值不同，则通过.当值不同时，我要求失败.

And I am using Fluent Assertions to compare it. But the problem is Fluent assertion fails only when the attribute count/names are not matching. If the json values are different it passes. I require to fail when values are different.

InstanceObjActual.Should().BeEquivalentTo(InstanceObjExpected);

例如，我将实际和预期的json进行如下比较.并使用上述比较方法使它们通过，这是错误的.

For example I have the actual and expected json to compare as below. And using the above way of comparing make them Pass which is wrong.

{
  "Name": "20181004164456",
  "objectId": "4ea9b00b-d601-44af-a990-3034af18fdb1%>"  
}

{
  "Name": "AAAAAAAAAAAA",
  "objectId": "4ea9b00b-d601-44af-a990-3034af18fdb1%>"  
}

推荐答案

我做了更多的挖掘工作，并且能够找出为什么OP的测试代码未按预期运行的原因.我能够通过安装并使用 FluentAssertions.Json nuget包来修复它.

I did a bit more digging and was able to find out why the OP's test code doesn't run as expected. I was able to fix it by installing and using the FluentAssertions.Json nuget package.

一件重要的事情:

请确保包含using FluentAssertions.Json，否则为false 肯定会发生.

Be sure to include using FluentAssertions.Json otherwise false positives may occur.

测试代码如下:

using FluentAssertions;
using FluentAssertions.Json;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using NUnit.Framework;

[TestFixture]
public class JsonTests
{
    [Test]
    public void JsonObject_ShouldBeEqualAsExpected()
    {
        JToken expected = JToken.Parse(@"{ ""Name"": ""20181004164456"", ""objectId"": ""4ea9b00b-d601-44af-a990-3034af18fdb1%>"" }");
        JToken actual = JToken.Parse(@"{ ""Name"": ""AAAAAAAAAAAA"", ""objectId"": ""4ea9b00b-d601-44af-a990-3034af18fdb1%>"" }");

        actual.Should().BeEquivalentTo(expected);
    }
}
