你如何在C#项目中嵌入app.config？

<?xml version="1.0" encoding="utf-8" ?><configuration>
  <appSettings>
    <add key="Setting1" value="Value1"/>
    <add key="Setting2" value="Value2"/>
  </appSettings>
</configuration>

using System;
using System.Configuration;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            string setting1 = ConfigurationManager.AppSettings["Setting1"];
            string setting2 = ConfigurationManager.AppSettings["Setting2"];

            Console.WriteLine($"Setting1: {setting1}");
            Console.WriteLine($"Setting2: {setting2}");
        }
    }
}
