c# - 日志文件似乎被另一个进程锁定

Question

我正在尝试使用下面给出的代码创建一个日志文件，但它抛出了

Process cannot access a file because it is being used by another process

代码如下:

string logFile = System.IO.Directory.GetCurrentDirectory() + "\\LogFile\\" + DateTime.Now.ToString("dd-MM-yyyy") + "TaskLogFile.txt";

      StreamWriter LogWriter;
      try
      {
          if (!File.Exists(logFile))
          {
              LogWriter = new StreamWriter(logFile);
              Console.WriteLine("Log File Created...");
          }
          else
          {
              LogWriter = File.AppendText(logFile);
              Console.WriteLine("Log File Appended...");
          }

          if (EX == null)
          {
              LogWriter.Write("\r\nLog Entry : ");
              LogWriter.WriteLine("{0} {1}", DateTime.Now.ToLongTimeString(), DateTime.Now.ToLongDateString());
              LogWriter.WriteLine("\nTask Id = {0} , Task Name = {1}, Service Name = {2} ", TaskId, TaskName, ServiceName);
              LogWriter.WriteLine("-----------------------------------------------------------------------------------------------------");
              LogWriter.Close();
          }

          else
          {
              LogWriter.WriteLine("\n Error : {0}, Error Location : {1},Task ID = {2}, Task Name : {3}, Service Name : {4} " + EX.ToString(), EX.StackTrace, TaskId, TaskName, ServiceName);
          }
      }

      catch (Exception ex)
      {

          LogWriter = File.AppendText(logFile);
          LogWriter.WriteLine("\n Error : {0}, Error Location : {1},Task ID = {2}, Task Name : {3}, Service Name : {4} " + ex.ToString(), Environment.StackTrace, TaskId, TaskName, ServiceName);

      }

此外，我正在使用其他异步方法调用此方法。

您的问题是日志文件可能被另一个进程锁定，或者如果它是异步的则被同一个进程锁定。

这是日志文件的典型问题，可以使用 FileShare.ReadWrite 轻松解决

File.Open(logFile, FileMode.Append, FileAccess.Write, FileShare.ReadWrite)
