（十）命令行配置

• 创建一个asp.net core解决方案CommandLineSample.，默认项目也是CommandLineSample
• 通过Nuget给项目中依赖项添加Microsoft.AspNetCore.All
• 第一种方式:
• Program.cs:

• 1 var builder = new ConfigurationBuilder().AddCommandLine(args);
  2             var configuration = builder.Build();
  3 
  4             Console.WriteLine($"name:{configuration["name"]}");
  5             Console.WriteLine($"age:{configuration["age"]}");
  6 
  7             Console.ReadKey();

• 右击项目，调试->应用程序参数输入：name=liuxh,age=30
• 运行结果：

• 　　第二种方式
• program.cs

•  1             var settings = new Dictionary<string, string>() { { "name","liuxh"},{ "age","18"} };
   2 
   3 
   4             var builder = new ConfigurationBuilder().AddInMemoryCollection(settings).AddCommandLine(args);
   5             var configuration = builder.Build();
   6 
   7             Console.WriteLine($"name:{configuration["name"]}");
   8             Console.WriteLine($"age:{configuration["age"]}");
   9 
  10             Console.ReadKey();
