Core的学习四：.Net Core读取配置文件（JSON文件）

appsettings.json

{ "Logging": { "LogLevel": {  "Default": "Information",  "Microsoft": "Warning",  "Microsoft.Hosting.Lifetime": "Information" } }, "option1": "Json", "option2": 2, //对象 "subsection": { "Id": 1, "Name": "Max" }, //数组 "wizards":  [  {  "Name": "Gand",  "Age": "10"  },  {  "Name": "Harry",  "Age": "17"  } ], "AllowedHosts": "*"}

Startup.cs

  public void Configure(IApplicationBuilder app, IWebHostEnvironment env)//,ILoggerFactory factory  {   #region Asp.Net Core读取配置文件（JSON文件）    {    //    WriteLine($"option1 = {this.Configuration["option1"]}");    WriteLine($"option2 = {this.Configuration["option2"]}");    //对象获取    WriteLine($"subsection_Id = {this.Configuration["subsection:Id"]}");    WriteLine($"subsection_Name = {this.Configuration["subsection:Name"]}");    //数组获取    WriteLine("wizards");    WriteLine($"wizardsFirst_Name = {this.Configuration["wizards:0:Name"]}");    WriteLine($"wizardsFirst_Age = {this.Configuration["wizards:0:Age"]}");    WriteLine($"wizardsSecond_Name = {this.Configuration["wizards:1:Name"]}");    WriteLine($"wizardsSecond_Age = {this.Configuration["wizards:1:Age"]}");   }
