嗨对不起，如果这是一个愚蠢的。
我创建了一个记录器类，它记录信息，我在不同的项目和记录信息中使用记录器类。我有一个要求，我需要在完成写入后发送日志文件的电子邮件附件。
但是文件路径位置在 Logger.cs 类中，我如何知道我正在使用记录器的项目中文件的位置。
** 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 我需要将日志文件作为附件发送 *
