1.9 配置框架：使用命令行配置提供程序接收命令行参数.pdf

直接在 launchSettings.json 中编辑命名行参数：

{
  "profiles": {
    "ConfigurationCommandLineDemo": {
      "commandName": "Project",
      "commandLineArgs": "CommandLineKey1=value1 --CommandLineKey2=value2 /CommandLineKey3=value3 -k1=k3"
    }
  }
}

static void Main(string[] args)
{
    var builder = new ConfigurationBuilder();
    //builder.AddCommandLine(args);
    #region 命令替换
    var mapper = new Dictionary<string, string> { { "-k1", "CommandLineKey1" } };
    builder.AddCommandLine(args, mapper);
    #endregion
    var configurationRoot = builder.Build();
    Console.WriteLine($"CommandLineKey1:{configurationRoot["CommandLineKey1"]}");
    Console.WriteLine($"CommandLineKey2:{configurationRoot["CommandLineKey2"]}");
    Console.ReadKey();
}
