C# write to log file class

In this article, there are several examples showing various ways to write text to a file. The first two examples use static convenience methods on the System. The third example shows how to add text to a file when you have to process each line individually as you write to the file. In the first three examples, you overwrite all existing content in the file. The final example shows how to append text to an existing file. These examples all write string literals to files. If you want to format text written to a file, use the Format method or C string interpolation feature.

Because if I remove AutoFlush and will flush the stream time to time may be by maintaining inner counter and when n records are written to buffer, I'd flush it, but what if less than n records are written and program terminates?

Is there any reason you can't use an open source logging framework such as NLog? It's pretty easy to set up to write to a file. Open the automatically created NLog. In theory, you don't even need "Dispose" this is managed code, after all. You do need to call "Close " somewhere. If the program closes gracefully, it should automagically flush and close - all your data should be written. If the program terminates abnormally - all bets are off as to what will or won't happen.

All you know is that your resources will be freed - but your data may or may not be written and the data file may or may not be corrupted. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

I am just wondering on a good way to write to log. Now I reflect on the following two questions, comments on which I expect from you : First is autoflushing - does it open and close file all the time? Improve this question.
