Log Parser - 通过MSUtill查询和通过C#代码读取记录

Question

我发现很多关于Log Parser的线程,但没有一个符合我的愿望,

我需要通过日志解析器select*from security来应用此查询

并获取事件行,然后逐行读取它们,知道我访问哪个列...

请帮忙...

应该是什么:1.通过LogParser.dll查询Windows事件(使用MSUtill库)2.获取并将行放在任何容器内3.逐行读取行4.能够分隔行的每个单元格,并读取它们分别像访问事件id列或消息列...

有事情,但我得到了他们,例如,这个人使用这个,采取单行,但我需要多行,我不知道接下来要转换什么:| 我需要使用什么类

LogQueryClass logger = new LogQueryClassClass();
            COMIISW3CInputContextClass inputContext = new COMIISW3CInputContextClassClass();
            string query = // i change it during test
            ILogRecord record = logger.Execute(query, inputContext).getRecord();

或者另一个使用它:似乎也返回单个结果

// prepare LogParser Recordset & Record objects
            ILogRecordset rsLP = null;
            ILogRecord rowLP = null;

            LogQueryClassClass LogParser = null;
            COMW3CInputContextClassClass W3Clog = null;

            double UsedBW = 0;
            int Unitsprocessed;
            double sizeInBytes;

            string strSQL = null;

            LogParser = new LogQueryClassClass();
            W3Clog = new COMW3CInputContextClassClass();

            try
            {
                //W3C Logparsing SQL. Replace this SQL query with whatever 
                //you want to retrieve. The example below 
                //will sum up all the bandwidth
                //Usage of a specific folder with name 
                //"userID". Download Log Parser 2.2 
                //from Microsoft and see sample queries.

                strSQL = //the query (i changed it during test)

                // run the query against W3C log
                rsLP = LogParser.Execute(strSQL, W3Clog);

                rowLP = rsLP.getRecord();

                Unitsprocessed = rsLP.inputUnitsProcessed;

                if (rowLP.getValue(0).ToString() == "0" ||
                    rowLP.getValue(0).ToString() == "")
                {
                    //Return 0 if an err occured
                    UsedBW = 0;
                    return UsedBW;
                }

                //Bytes to MB Conversion
                double Bytes = Convert.ToDouble(rowLP.getValue(0).ToString());
                UsedBW = Bytes / (1024 * 1024);

最好的查询我找到了这个,它在registery内搜索(我没有原始查询,因为我改变了它

ILogRecordset rs = null;
            try
            {
                LogQueryClass qry = new LogQueryClass();
                COMRegistryInputContextClass registryFormat = new COMRegistryInputContextClass();
                string query = //Chnaged it
                rs = qry.Execute(query, registryFormat);
                for (; !rs.atEnd(); rs.moveNext())
                    Console.WriteLine(rs.getRecord().toNativeString(","));
            }
            finally
            {
                rs.close();
            }

还有一些东西,似乎将数据返回给SQL而不是活动对象:|

因为我要编写服务,我希望尽可能少地访问交换数据的数据库,只需存储当前数据

- 编辑:

让我补充一下,我的查询(使用传递"log parser.exe"参数)是这样的,但是对于我来说,在服务中调用exe文件真是太粗鲁了.

myProc.StartInfo.Arguments = " \"select * INTO AuditLogParser from \\\\" + Dns.GetHostName() +
                                         "\\security WHERE TimeGenerated >= '" + startDate +
                                         "' and TimeGenerated <'" + endDate +
                                         "' and (eventid=560 or eventid=540)\" -o:SQL -server:\"" +
                                         Dns.GetHostName() +
                                         "\\sqlexpress\"  -database:SecurityLog -driver:\"SQL Server\" -username:TrainAudit -password:Password.110 -createtable:OFF";

Answer 1

以下示例代码使用LogParser从名为的本地目录中读取文件名和大小 C:\Bat

LogQueryClass logQuery = new LogQueryClassClass();

COMFileSystemInputContextClass inputFormat = new COMFileSystemInputContextClassClass();
inputFormat.recurse = 0;

String strQuery = @"SELECT Name, Size FROM 'C:\Bat\*.*' ORDER BY Name ASC";

ILogRecordset results = logQuery.Execute(strQuery, inputFormat);
while (! results.atEnd())
{
    Console.WriteLine(String.Format("File: {0} Size: {1}", results.getRecord().getValue("Name"), results.getRecord().getValue(1)));
    results.moveNext();
}

请注意,我可以通过查询中的列名称或列索引来访问该列.
