c# - 如何从复杂的 JSON 格式文件 C# 中获取特定信息

问题描述

我试图从一个复杂的 JSON 文件中获取所有“方法名”“全名”和属性 [] 值的列表，我试图实现一个基本模型来读取顶层，但所有内容都返回为 null；

public class TestRun
{
    public string @id { get; set; }
    public string @name { get; set; }
    public string @fullname { get; set; }
    public string testcasecount { get; set; }
    public TestSuite[] TestSuite { get; set; }
}

public class TestSuite
{

}

public class ScriptModel
{
    public TestRun[] TestRun { get; set; }

}

JSON看起来像这样；从根级别有大量嵌套的“test-suites”和“test-fixtures”

            "test-suite": {
                "@type": "TestSuite",
                "@id": "0-1030",
                "@name": "Example__Exampledll",
                "@fullname": "Example",
                "@runstate": "Runnable",
                "@testcasecount": "24",
                "test-suite": {

解决方案

您使用特殊符号@它不会更改变量名称，此符号有时用于使用变量名称等关键字var @object = "sample"

你需要使用JsonProperty属性

public class TestRun
{
    [JsonProperty("@id")]
    public string Id { get; set; }

    [JsonProperty("@name")]
    public string Name { get; set; }

    [JsonProperty("@fullname")]
    public string FullName { get; set; }

    [JsonProperty("@testcasecount")]
    public string TestCaseCount { get; set; }

    [JsonProperty("test-suite")]
    public TestSuite[] TestSuite { get; set; }
}
