こんにちは、これがばかげている場合は申し訳ありません。
情報をログに記録する Logger クラスを作成し、さまざまなプロジェクトで Logger クラスを使用して情報を記録しています。書き込み終了後にログ ファイルの添付ファイルを電子メールで送信する必要があるという要件があります。
しかし、ファイルパスの場所は Logger.cs クラスにあります。ロガーを使用しているプロジェクト内のファイルの場所を知るにはどうすればよいですか。
** Logger.cs **
public class Logger
{
// logFilePath where to write?
readonly string logFilePath = string.Empty;
/// <summary>
/// Constructor
/// </summary>
public Logger()
{
String filePath = string.Format("{0:yyyy-MM-dd}", DateTime.Now);
// This is the text file created with time stamps
var folderName = ConfigurationManager.AppSettings["FolderToCreate"];
String txtFile = string.Format("Log{0:yyyy-MM-dd hh-mm-ss-tt}", DateTime.Now);
// Given in config to read the path
var localhostizedLetter = ConfigurationManager.AppSettings["localhostDriveLetter"]+"//";
//Create directory
string pathString = Path.Combine(localhostizedLetter, folderName);
if (!Directory.Exists(pathString))
{
Directory.CreateDirectory(pathString);
}
// Create a folder inside directory
// If folder exists dont create it
pathString = Path.Combine(pathString, filePath);
if (!Directory.Exists(pathString))
{
Directory.CreateDirectory(pathString);
}
// create a file inside d://DataSummarisationDatetime.now//datetimewithtimestamp.txt
// if exists please dont create it.
pathString = Path.Combine(pathString, txtFile);
if (!Directory.Exists(pathString))
{
// here my file is created and opened.
// so I m doing a try catch to make sure if file is opened we are closing it so that nother process can use it
File.Create(pathString).Dispose();
var fileInfo = new FileInfo(pathString);
IsFileLocked(fileInfo);
}
logFilePath = pathString;
//logFilePath = ConfigurationManager.AppSettings["localhostDriveLetter"] + "\\" + "RetailerfeedLogFiles" + "\\" + string.Format("RetailerFeed{0:yyyy-MM-dd hh-mm-ss-tt}", DateTime.Now) + ".txt";
}
/// <summary>
/// To check if File is opened by another process.
/// </summary>
/// <param name="file"></param>
/// <returns></returns>
private bool IsFileLocked(FileInfo file)
{
FileStream stream = null;
try
{
stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None);
}
catch (IOException)
{
//the file is unavailable because it is:
//still being written to
//or being processed by another thread
//or does not exist (has already been processed)
return true;
}
finally
{
if (stream != null)
stream.Close();
}
//file is not locked
return false;
}
/// <summary>
/// Log message using textwriter
/// </summary>
/// <param name="logMessage"></param>
/// <param name="w"></param>
public static void Log(string logMessage, TextWriter w)
{
w.Write("\r\n" + DateTime.Now + " " + logMessage);
w.Flush();
}
/// <summary>
/// Call this function to log your message
/// </summary>
/// <param name="textLog"></param>
public void Log(string textLog)
{
StreamWriter sw = null;
if (!File.Exists(logFilePath))
{
try
{
sw = File.CreateText(logFilePath);
}
catch (Exception exception)
{
throw exception;
}
finally
{
sw.Dispose();
}
}
try
{
using (StreamWriter w = File.AppendText(logFilePath))
{
Log(textLog, w);
w.Close();
}
}
catch (Exception exception)
{
throw exception;
}
}
}
** RetailerFeed.cs **
public partial class RetailerFeeds : Form
{
private Logger _logger = new Logger();
_logger.Log(" ");
_logger.Log(" Total no.of scrapes/retailers to Process : " + scrapesRun.Count());
_logger.Log(" Starting RetailerFeeds Processing " );
_logger.Log(" ");
_logger.Log(" Processing : " + scrape.Retailer.Description);
_keepItDry.SendRetailerFeedNotification("Ended RetailerFeeds Interface " , stringBuilder.ToString());
}
- SendRetailerFeedNotification ログファイルを添付ファイルとして送信する必要があります *
