我如何在外部applicationatesteTsEttings.json文件中配置过滤器lc.filter.byincludingonly（lc =＆gt; lc.properties.containskey（“ log_gp”）？我尝试过

  "Filter": [
    {
      "Name": "ByIncludingOnly",
      "Args": {
        "expression": "Contains(Properties, 'log_gp')"
      }

dotnet add package serilog.expressions

然后：

  "Using": ["Serilog.Expressions"],
  "Filter": [
    {
      "Name": "ByIncludingOnly",
      "Args": {
        "expression": "IsDefined(log_gp)"
      }
    }
  ]
