【问题描述】：

我正在尝试使用 Serilog.Sinks.File 配置 Serilog 两个不同的文件来存储 MVC 项目和另一个 Serilog.Sinks.MSSqlServer 我的 SQL 服务器表。如何创建两个不同的地方存储错误文件？

这是我的 appsettings.json 文件代码

"FileLog": 
    "Using": [ "Serilog.Sinks.File" ],
    "WriteTo": [
      
        "Name": "File",
        "Args": 
          "path": "Logs/web-log-.log",
          "rollingInterval": "Day"
        
      
    ]
  ,
  
    "DatabaseLog": 
    "Using": [ "Serilog.Sinks.MSSqlServer" ],
    "MinimumLevel": "Warning",
    "WriteTo": [
      
        "Name": "MSSqlServer",
        "Args": 
          "connectionString": "Server = DESKTOP-P9UP8PR\\SQLEXPRESS; Database = MVC_Project; User Id = MizanurRahman; Password = 682672;",
          "tableName": "Logs",
          "autoCreateSqlTable": true
        
      
    ]
  ,

【参考方案1】：

我不使用数据库日志记录，但是对于多个文件日志记录 appsettings.json 文件会是这样的：

"Serilog": 
    "MinimumLevel": 
      "Default": "Debug",
      "Override": 
        "Default": "Information",
        "Microsoft": "Warning",
        "Microsoft.Hosting.Lifetime": "Information"
      
    ,
    "WriteTo": [
      
        "Name": "Logger",
        "Args": 
          "configureLogger": 
            "Filter": [
              
                "Name": "ByIncludingOnly",
                "Args": 
                  "expression": "(@Level = 'Error' or @Level = 'Fatal' or @Level = 'Warning')"
                
              
            ],
            "WriteTo": [
              
                "Name": "File",
                "Args": 
                  "path": "Logs/MyFirstLogFile.log",
                  "outputTemplate": "Timestamp:o [Level:u3] (SourceContext) MessageNewLineException",
                  "rollingInterval": "Day",
                  "retainedFileCountLimit": 7
                
              
            ]
          
        
      ,
      
        "Name": "Logger",
        "Args": 
          "configureLogger": 
            "Filter": [
              
                "Name": "ByIncludingOnly",
                "Args": 
                  "expression": "(@Level = 'Information' or @Level = 'Debug')"
                
              
            ],
            "WriteTo": [
              
                "Name": "File",
                "Args": 
                  "path": "Logs/MySecondLogFile.log",
                  "outputTemplate": "Timestamp:o [Level:u3] (SourceContext) MessageNewLineException",
                  "rollingInterval": "Day",
                  "retainedFileCountLimit": 7
                
              
            ]
          
        
      
    ],
    "Enrich": [
      "FromLogContext",
      "WithMachineName"
    ],
    "Properties": 
      "Application": "MyApplication"
