我的 Windows 服务需要将一个事件日志的内容保存到一个文件中。这是由 EventLogSession.ClearLog 完成的。但是,我不能强制它直接将事件日志保存到 CSV。保存格式为EVTX。
EventLogSession els = new EventLogSession();
//stel de filename samen door het appdata pad te combinen met een tempfile name
string tempData = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), "templog.csv");
// Clears all the events and archives them to the .evtx file
els.ClearLog(eventLogName, tempData); // Backup File Path
我如何强制 EventlogSession 类直接保存到 CSV,或者,如果那是不可能的。如何将 EVTX 转换为 CSV(使用 C# 或 VB.net)
谢谢!
最佳答案
使用 Log Parser 提供的 API 可以很容易地做到这一点。
下载并安装 Log Parser 2.2
添加对 COM 库“MS Utility 1.0 类型库 - LogParser 接口(interface)集合”的引用。搜索 Log 可显着缩小列表范围。
更改引用的属性,使其不嵌入互操作类型。 如果你不这样做,你会得到这样的编译错误: 无法嵌入互操作类型“MSUtil.COMCSVOutputContextClassClass”。请改用适用的界面。
LogParser 帮助文件的内容对 API 有很好的引用,但我已经包含了我在代码中使用的部分。
using System;
using MSUtil;
namespace LogParserTest
{
using LogQuery = LogQueryClassClass;
using EventLogInput = COMEventLogInputContextClassClass;
using CSVOutput = COMCSVOutputContextClassClass;
using XMLOutput = COMXMLOutputContextClassClass;
class Program
{
static void Main(string[] args)
{
try
{
// Instantiate the LogQuery object
LogQuery oLogQuery = new LogQuery();
// Instantiate the Event Log Input Format object
EventLogInput eventInputFormat = new EventLogInput();
// When set to "FW", events are retrieved from the oldest to the
// newest. When set to "BW", events are retrieved from the newest
// to the oldest.
eventInputFormat.direction = "FW";
// Event text messages often span multiple lines. When this parameter
// is set to "ON", the EVT input format preserves readability of the
// messages by removing carriage-return, line-feed, and multiple space
// characters from the message text.
// When this parameter is set to "OFF", the EVT input format returns
// the original message text with no intervening post-processing.
eventInputFormat.formatMessage = true;
eventInputFormat.binaryFormat = "ASC";
eventInputFormat.stringsSep = ",";
CSVOutput csvOutputFormat = new CSVOutput();
// ON: always write the header;
// OFF: never write the header;
// AUTO: write the header only when not appending to an existing file.
csvOutputFormat.headers = "ON";
// Setting this parameter to "ON" causes the CSV output format to write
// a tab character after each comma field separator, in order to
// improve readability of the CSV output. Note that using tabs between
// field values might generate output that is not compatible with
// certain spreadsheet applications.
csvOutputFormat.tabs = false;
// ON: always enclose field values within double-quote characters;
// OFF: never enclose field values within double-quote characters;
// AUTO: enclose within double-quote characters only those field
// values that contain comma (,) characters.
csvOutputFormat.oDQuotes = "AUTO";
// This parameter specifies the date and/or time format to use when
// formatting values of the TIMESTAMP data type.
csvOutputFormat.oTsFormat = "yyyy-MM-dd";
// 0 is the system codepage, -1 is UNICODE.
csvOutputFormat.oCodepage = -1;
// 0: existing files are appended with the output;
// 1: existing files are overwritten with the output;
// 2: existing files are left intact, discarding the output.
csvOutputFormat.fileMode = 1;
