c# 如何获取JSON文件以及如何获取Config文件(framework 和 net .Core)

framework版本

using System.Configuration;

public static string Process => ConfigurationManager.AppSettings["Process"];

在App.config 添加Key即可获取；

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="Process" value="Kill" />
</appSettings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.1" />
</startup>
</configuration>

.Core适用

添加必备nuget包:Microsoft.Extensions.Configuration.Json

json文件右键属性高级为始终复制

//蓝色字体为添加的.Json名称

//Json有嵌套加冒号

private static IConfigurationRoot Configuration = new Microsoft.Extensions.Configuration.ConfigurationBuilder().AddJsonFile("config.json").Build();

 public string GetData1{ get; set; } = Configuration["One“];

 public string GetData2{ get; set; } = Configuration["One“:"Two”];
