+Q1.1：
+
+1.using var csv = new CsvReader(logFile, config);
+
+​             csv.GetRecords<LogRecord>()
+
+通过在LogFileParser.cs中定义一个继承自ClassMap<LogRecord>的映射类LogRecordMap实现的。通过Map(m => m.LineNo).Index(0);之类，将第0列设置为行号，将第3列设置为Message。
+
+2.var root = JsonDocument.Parse(logRecord.Message).RootElement;
+
+root.TryGetProperty("event", out var eventElement)
+
+ventElement.GetString() switch {    "call" => ...,    "request" => ...,    "internal" => ... }
+
+3.调用了 System.Text.Json 库中的 JsonSerializer.Deserialize<T>(string, JsonSerializerOptions)
+
+给每个属性加上了property: JsonRequired特性，如果缺失特性，会抛出异常
+
+定义了JsonSerializerOptions的options静态对象，设置了PropertyNamingPolicy = JsonNamingPolicy.KebabCaseLower
+
+Q1.2：
+
+Dictionary<string, string> KeyValueVisitor.Dump(LogEntry entry)
+
+TResult CallLogEntry.Accept<TResult>(ILogEntryVisitor<TResult> visitor)

+Dictionary<string, string> KeyValueVisitor.Visit(CallLogEntry entry)
