C#中当前流行的日志框架有NLog、Log4Net、及SeriLog,在这里我们简单介绍SeriLog日志框架的应用
1、日志基础
(1)、日志等级
(2)、日志接收器
序号 接收器 说明
1 Console 输出到控制台
2 Debug 输出到VS的Debug窗口
3 Trace 输出到VS的控制台
4 File 输出到文件
5 Rolling File 输出到滚动文件
6 MongoDB 输出到数据库MongoDB
7 LiteDB 输出到文件数据库LiteDB
8 SQLite 输出到文件数据库SQLite
9 SignalIR 输出为SignalIR服务
10 HTTP 输出到REST服务
2、安装Serilog和Serilog.Sinks.File
在工具/NuGet管理器中安装。
3、程序实现(各个级别存在一起)
(1)、界面
(2)、程序
public Form1()
{
InitializeComponent();
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.Enrich.FromLogContext()
.WriteTo.File(Path.Combine(Environment.CurrentDirectory, "FileSeriLog.txt"),rollingInterval:RollingInterval.Day)
.CreateLogger();
}
private void button1_Click(object sender, EventArgs e)
{
Log.Information("click Button1, textBox1.Text is:" + this.textBox1.Text);
}
private void button2_Click(object sender, EventArgs e)
{
Log.Debug("click Button2, textBox2.Text is:" + this.textBox2.Text);
}

4、程序实现(不同级别存放不同文件夹)
界面同上
(1)、程序
public Form1()
{
InitializeComponent();
//不同级别存放不同文件夹
string LogFilePath(string LogEvent) => $@"{AppContext.BaseDirectory}00_logs\{LogEvent}\log.log";
string SerilogOutputTemplate = "{NewLine}{NewLine}Date:{Timestamp:yyyy-MM-dd HH:mm:ss.fff}{NewLine}LogLevel:{Level}{NewLine}Message:{Message}{NewLine}{Exception}" + new string('-', 50);
Log.Logger = new LoggerConfiguration()
.Enrich.FromLogContext()
.MinimumLevel.Debug() // 所有Sink的最小记录级别
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Debug).WriteTo.File(LogFilePath("Debug"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Information).WriteTo.File(LogFilePath("Information"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Warning).WriteTo.File(LogFilePath("Warning"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Error).WriteTo.File(LogFilePath("Error"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Fatal).WriteTo.File(LogFilePath("Fatal"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.CreateLogger();
}
private void button1_Click(object sender, EventArgs e)
{
Log.Information("click Button1, textBox1.Text is:" + this.textBox1.Text);
}
private void button2_Click(object sender, EventArgs e)
{
Log.Debug("click Button2, textBox2.Text is:" + this.textBox2.Text);
}
