使用Serilog记录日志

默认日志：

Console.WriteLine("日志内容...");

Serilog日志：

Log.Error("OMG its on fire!");

Serilog日志显示效果：

1.安装依赖包：

Serilog 和 Serilog.Sinks.BrowserConsole

注意由于Serilog.Sinks.BrowserConsole现在还没有正式版本，所以必须在“程序包管理控件台”用命令安装，命令如下：

dotnet add BlazorApp3 package Serilog.Sinks.BrowserConsole -v 1.0.0-dev-00012

2.创建日志实例：

public class Program { public static async Task Main(string[] args) { var builder = WebAssemblyHostBuilder.CreateDefault(args); builder.RootComponents.Add<App>("app"); builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) }); builder.Services.AddSingleton<Markdig.MarkdownPipeline>(sp => new Markdig.MarkdownPipelineBuilder() .UseAdvancedExtensions() .UseSyntaxHighlighting() .Build()); Log.Logger = new LoggerConfiguration() .MinimumLevel.Debug() .WriteTo.BrowserConsole() .CreateLogger(); await builder.Build().RunAsync(); } }

3.Serilog日志例子：

@page "/loging" @using Serilog <div class="row mt-1"> <button class="btn btn-primary" @onclick="LogMessage">Log Message with Serilog</button> </div> <div class="row mt-1" > <button class="btn btn-warning" @onclick="LogWarning">Log Warning with Serilog</button> </div> <div class="row mt-1"> <button class="btn btn-danger" @onclick="LogError" >Log Error with Serilog</button> </div> @code { private void LogMessage() { Log.Information("Information Message"); } private void LogWarning() { Log.Warning("Warning Message"); } private void LogError() { Log.Error("OMG its on fire!"); } }

引深：

还可以将日志同时记录到服务器和客户端浏览器中：
