在 IronPDF 的最近版本中，日誌中的原生異常信息將包含一個特定的問題代碼：[Issue Code IRONPDF-NATIVE-EXCEPTION]。以下顯示了一個此類異常信息的示例：

IronPdf.Exceptions.IronPdfNativeException: Error while generating PDF from HTML: 'Error while rendering pdf from html for job group 0: 'Error during dev tools execution: {"method":"Inspector.targetCrashed","params":{}}''.

可能原因

IronPDF 原生異常通常源於 IronPDF 中使用的 C++ 代碼，涉及到使用 Chrome PDF 渲染引擎的 IronPdf.Native.Chrome 包的各種問題。

解決方案

要獲得與原生異常相關問題的幫助，請提交工程支持請求，並提供完整的日誌文件以便進一步調查。

通過將以下代碼片段包含在您的項目中啟用原生日誌記錄：

// Set the path for the log file. 
// This can be a directory name or a specific file path. Here, we set it to "Default.log".
IronPdf.Logging.Logger.LogFilePath = "Default.log";

// Enable logging for all modes to capture comprehensive details
IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;

// Set the path for the log file. 
// This can be a directory name or a specific file path. Here, we set it to "Default.log".
IronPdf.Logging.Logger.LogFilePath = "Default.log";

// Enable logging for all modes to capture comprehensive details
IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;

' Set the path for the log file. 
' This can be a directory name or a specific file path. Here, we set it to "Default.log".
IronPdf.Logging.Logger.LogFilePath = "Default.log"

' Enable logging for all modes to capture comprehensive details
IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All

IronPDF 創建的日誌文件通常位於部署 DLL 的/bin 目錄中，或者您可以設置自定義IronPdf.Logging.Logger.LogFilePath來將日誌文件存儲在特定位置。相關日誌文件包括：
