步骤1：安装此NuGet软件包“ Serilog.Sinks.Elasticsearch”
步骤2：在App.config或Web.config中添加它
<appSettings> <add key="elasticsearchURL" value="your_URL" /> <add key="elasticsearchuserName" value="your_Username" /> <add key="elasticsearchpassword" value="your_Password" /> <add key="elasticsearchIndex" value="indexname-{0:yyyy.MM.dd}" /> <!-- make sure index start with small letter --></appSettings>步骤3：在main（）的program.cs或Application_Start（）的Global.asax中添加它
Log.Logger = new LoggerConfiguration() .MinimumLevel.Debug() .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri(ConfigurationManager.AppSettings["elasticsearchURL"])) { AutoRegisterTemplate = true, ModifyConnectionSettings = x => x.BasicAuthentication(ConfigurationManager.AppSettings["elasticsearchuserName"], ConfigurationManager.AppSettings["elasticsearchpassword"]), IndexFormat = ConfigurationManager.AppSettings["elasticsearchIndex"] }) .CreateLogger();步骤4：通过添加将日志记录到所需的位置
using Serilog; Log.Error("Your_Message", ex); Log.CloseAndFlush();
