Does the .net framework provides async methods for working with the file-system?

由 五迷三道 提交于 2019-11-30 06:23:54
Does the .net framework has an async built-in library/assembly which allows to work with the file system (e.g. File.ReadAllBytes , File.WriteAllBytes )? Or do I have to write my own library using the async Methods of StreamReader and StreamWriter ? Something like this would be pretty nice: var bytes = await File.ReadAllBytes("my-file.whatever"); Does the .net framework has an async built-in library/assembly which allows to work with the file system Yes. There are async methods for working with the file system but not for the helper methods on the static File type. They are on FileStream . So,

How to WriteAllLines in C# without CRLF

由 半腔热情 提交于 2019-11-28 10:59:26
I'm using C# and am trying to output a few lines to an ASCII file. The issue I'm having is that my Linux host is seeing these files as: ASCII text, with CRLF line terminators I need this file to be just: ASCII text The CRLF is causing some issues and I was hoping there was a way in C# to just create the file formatted in the way I want. I'm basically using this code: string[] lines = { "Line1", "Line2" }; File.WriteAllLines(myOutputFile, lines, System.Text.Encoding.UTF8); Is there an easy way to create the file without the CRLF line terminators? I can probably take care of it on the Linux side
