LogParser crashes without error in C#
我正试图在C应用程序中实现MS LogParser。这会编译logquery.executeBatch()方法上的细微但无法解释的崩溃。Try/Catch块不会捕获它,除非我对szQuery进行了专门的变形,这表明一切都正常工作,我只是没有得到任何输出。
有没有想过它为什么会崩溃,或者我在哪里可以找到一些日志?

}
使用Execute而不是ExecuteBatch:
1 | MSUtil.ILogRecordset RecordSet = logQuery.Execute(query, oInputFormat) |
如果要在示例代码中导出到csv,则需要通过添加到输出文件名并运行executeBatch来更改查询:
1 | string szQuery ="SELECT Folder, User, Record, DB, TO_LOCALTIME(Timestamp) AS DateTime, Operation, Checked **INTO c:\out\out.csv** FROM" + szFileName +" ORDER BY DateTime DESC"; |
