File.AppendAllText与StreamWriter [英] File.AppendAllText vs StreamWriter

问题描述

我想创建一个日志文件来跟踪我的应用程序中的某些操作.在我的情况下，一个会话中我想每分钟至少记录50次.当前我正在使用StremWriter创建日志文件.

I want to create a log file to track some operations in my Application.In my scenario within one session I wanna to log at least 50 time per min.currently im using StremWriter to create log file.

 public static StreamWriter InitializeStream(string path)
    {
        /*ensuring whether thread safe or not*/
        lock (mylock)
        {
            if (null == _stream)
            {
                var fileStream = new FileStream(path, FileMode.OpenOrCreate, FileAccess.ReadWrite);
                _stream = new StreamWriter(fileStream);                    

                return _stream;
            }
            return _stream;
        }
    }

//logging operation
StreamHandler.Log(path)

还是有点困惑选择AppendAllText或StreamWriter. 我可以直接使用AppendAllText而不是StreamWriter方法吗?(性能)

Still im bit confuse to selecting AppendAllText or StreamWriter. Instead of StreamWriter way can i get advantage using AppendAllText Directly?(Performance)

推荐答案

请勿在循环内使用AppendAllText()，因为它在内部使用StremWriter，其中流对象将在每次迭代时进行初始化和处理.

Do not use AppendAllText() inside the loop because it uses StremWriter internally where stream object will be initialized and disposed on each iteration.
