0x02 How to write to a file with C# in 2020 - StackOverflow doesn’t get it right

  • ‘I often find myself googling “simple” questions like how to write text to a file in the most quickly and effectively way. Most results are either blog posts using .NET 2 as an example, or StackOverflow answers from 2010. Common for all samples is that only the essential lines of code are added, and no focus on crucial aspects like error handling are highlighted.’
  • File.WriteAllText.
  • File.CreateText.
  • FileStream, a good choice for writing asynchronously to a file from .NET is using the FileStream class. Add true (useAsync parameter) as the last parameter to the FileStream constructor. This tells the FileStream to use asynchronous IO.
