c#读取二进制文件 文件结束标志

FileStream fs = File.OpenRead(path);
BinaryReader brReader = new BinaryReader(fs);

 while (brReader.BaseStream.Position < brReader.BaseStream.Length)
 {
     //TODO
 }

 brReader.Close();

            using (BinaryReader br = new BinaryReader(fs))
            {
                while (br.PeekChar() > -1)
                {
                    //TODO
                }
            }

 以上两种方法可以判断文件结束

下边是简单记录日志时候用的写入到txt文件里的方法

string logpath = Settings.LogPath;//d:logs
string logFileName = DateTime.Now.ToString("yyyy-MM-dd") + ".txt";
string logFilePath = logpath + "\" + logFileName;
string log = DateTime.Now.ToString() + ":  " + e.Message;
  
if (!File.Exists(logFilePath)) File.Create(logFilePath).Close();
using (StreamWriter sw = File.AppendText(logFilePath))
{
    sw.WriteLine("{0}", log);
    sw.Flush();
    sw.Close();
}
