这让我有点发疯，所以如果有人能帮忙，我将非常感激！
我正在尝试将我的信息记录到日志文件中，因此我使用了 Logger 类。
** Logger.cs **
public class Logger : IDisposable
{
private readonly FileStream _file; //Only this instance have a right to own it
private readonly StreamWriter _writer;
private readonly object _mutex; //Mutex for synchronizing
/// <summary>
/// Call this function to use the text file
/// </summary>
/// <param name="logPath"></param>
public Logger(string logPath)
{
if (logPath != null) _file = new FileStream(logPath, FileMode.Append);
_writer = new StreamWriter(_file);
_mutex = new object();
}
// Log is thread safe, it can be called from many threads
public void Log(string message)
{
lock (_mutex)
{
//_writer.Write("\r\nLog Entry : ");
// _writer.WriteLine("{0} {1}", DateTime.Now.ToLongTimeString(),
//DateTime.Now.ToLongDateString());
_writer.WriteLine("{0} {1}", DateTime.Now.ToString("yyyy-MM-dd"),
DateTime.Now.ToLongTimeString());
_writer.WriteLine(message);
}
}
/// <summary>
/// Call this function when it says file is already been using somewhere
/// </summary>
public void Dispose()
{
_writer.Dispose(); //Will close underlying stream
}
}
** 我的应用程序使用 Logger 类 **
private void button1_Click(object sender, EventArgs e)
{
// This is the file path after d://dashboardLogfiles
String filePath = string.Format("{0:yyyy-MM-dd}", DateTime.Now);
// This is the text file created with time stamps
String txtFile = string.Format("DataSummarisation{0:yyyy-MM-dd hh-mm-ss-tt}", DateTime.Now);
// Given in config to read the path
var localhostizedLetter = @"d:/";
//Create directory
string pathString = Path.Combine(localhostizedLetter, "DataSummarisationLogfiles");
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);
}
_logger = new Logger(pathString);
_logger.Log("Log File Created");
_logger.Dispose();
ThreadStart starter = () => MigrateProductStats(123, 0, pathString);
var thread = new Thread(starter);
thread.Start();
}
** 我的函数使用相同的记录器路径 **
private void MigrateProductStats(object corporationIdObj, object brandIdObj, object logFilePath)
{
_logger = new Logger(logFilePath.ToString());
_logger.Log("Am I still writing to same file?");
_logger.Dispose();
for (int i = 0; i <= 10;i++ )
{
DoProductStatsForCorporation(123, logFilePath.ToString());
}
}
private void DoProductStatsForCorporation(int corporationId, string logFilePath)
{
_logger = new Logger(logFilePath);
_logger.Log("Am I still writing to same file second time?");
_logger.Dispose();
}
** 上述场景有效 **
** 但我希望传递对象而不是路径以避免 Reinstatiaitng **
ThreadStart starter = () => MigrateProductStats(123, 0, _logger);
var thread = new Thread(starter);
thread.Start();
在上述情况下，在我的按钮单击中，我正在处理记录器并将路径发送到函数 DoProductStatsForCorporation 和 MigrateProductStats，而不是如果我尝试发送 _logger 对象而不处理它并避免在我的子函数中重新启动我收到错误无法写入文件，因为它被另一个进程使用。
我希望这是有道理的！
任何有关这方面的指导将不胜感激，因为我非常不知道该去哪里。
