關於Net Core 配置除appsettings.json檔案之外的json檔案

在netcore啟動時進行讀取配置

 Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder
                    .ConfigureAppConfiguration(delegate (WebHostBuilderContext hostingContext, IConfigurationBuilder config)
                    {
                        
 
try
                        {
                            // 讀取根目錄中Areas資料夾下所有的json
                            DirectoryInfo directoryInfo = new DirectoryInfo(Path.Combine(AppContext.BaseDirectory, "Areas"));
                            if (directoryInfo.Exists)
                            {
                                FileInfo[] files 
 
= directoryInfo.GetFiles("*.json", SearchOption.AllDirectories);
                                foreach (FileInfo fileInfo in files)
                                {
                                    config.AddJsonFile(fileInfo.FullName, optional: true, reloadOnChange: true);
                                    Console.WriteLine(
 
"載入模組配置檔案:" + fileInfo.Name);
                                }
                            }
                        }
                        catch (Exception ex)
                        {
                            Console.WriteLine("載入模組配置檔案失敗:" + ex.Message);
                        }
                    })
                    .UseContentRoot(Directory.GetCurrentDirectory())
                    .UseUrls("http://localhost:7000")
                    .UseStartup<Startup>();
                });

這樣就可以將Areas資料夾下的所有json檔案配置都載入進系統
