On my machine, the code takes around 100 ms. In the example, I generate 1 million lines and store them in the output.txt file. Lines.ForEach(i => sb.AppendLine($"Line number ")) įile.WriteAllText("output.txt", content) Let's create a scenario for the rest of the post, where a large amount of data should be stored and use WriteAllText to write the data to a file: var sb = new StringBuilder() This approach can be fine for smaller text files, but shouldn't be the default choice when handling larger amounts of data. The example produces a file named output.txt with the content of the writeMe variable. Take a look at the simplicity of this approach: var writeMe = "File content" įile.WriteAllText("output.txt", writeMe) And I understand why since I have been doing this for years. The reason I mention this as the first example, is because it's what 95% (maybe more?) of people are doing.
The first example of writing a string to a file is using the File.WriteAllText method. This post is my attempt to sum up what I've learned over the years. Common for all samples is that only the essential lines of code are added, and no focus on crucial aspects like error handling is highlighted. NET 2 as an example, or StackOverflow answers from 2010. Most results are either blog posts using. I often find myself googling "simple" questions like how to write text to a file in the quickest and effective way. Today's tip isn't exactly about a hot new version of ASP.NET Core or anything like that.
