C# Wrapper em torno da biblioteca de correspondência do Yara Pattern.
Use assinaturas formam Loki ou Yara.

// Iterate over matches

// Log errors
}Para o uso de varredura assíncrona, deve chamar métodos de destruição:
YaraSharp . CYaraSharp YSInstance = new CYaraSharp ( ) ;
YaraSharp . CContext YSContext = new YaraSharp . CContext ( ) ;
YaraSharp . CRules YSRules = YSInstance . CompileFromFiles ( RuleFilenames , null , out Errors ) ;
// Async here
YSRules . Destroy ( ) ;
YSContext . Destroy ( ) ; Documentação da API da Líbia C Para uma visão geral sobre como usar a Líbia.
