前言
在之前的文章中有講到AspNetCore多環境配置文件的應用，我們根據自己多種環境分別配置多個appsettings.$EnvironmentName.json文件。
在實際的開發中我們可能會遇到不只一個配置文件，如當我們使用log4net日志庫時，喜歡使用單獨的log4net.config配置文件。并且我們還遇到不同環境下的配置文件還存在差異。這時我們可能可以效仿appsettings.json多環境配置的風格實現多環境配置文件。
配置log4net
新建Web項目
安裝Microsoft.Extensions.Logging.Log4Net.AspNetCore
創建兩個環境的配置文件分別如圖，并設置文件屬性使其在發布時能夠復制到根目錄
兩個配置文件內容如下，例如我們這里生產環境的配置文件多增加一個KafkaAppender使日志發送至kafka消息丟列中，然后kafka的消費者將日志消費至ES集群,而本地開發的日志則沒必要進行上傳ES。

在Program.cs中添加log4net配置如下圖
// ===============多環境log4net配置===============
IWebHostEnvironment environment = builder.Environment;
var configName = "log4net" + (environment.IsProduction() ? string.Empty : environment.EnvironmentName) + ".config";
builder.Logging.AddLog4Net(configName, watch: true);
// ===============多環境log4net配置===============
現在所有的配置都完成了。
