C#- What is the best way for write text to a file from array of strings.

Question

Group,

I'm looking for new and fun ways to write an array of strings to a .txt file. -This file will be rewritten every time its called and saved. -The file name will be dynamic enough that the .exe will know what string goes where.

For example:

 ~/someFile.exe "fileName" "string|string|string|"

-In this example someFile.exe is called to write strings to this "fileName".

Any suggestions?

Answer 1

If this isnt the exact call your looking for, it will be in the system.io.file namespace.

In your exe you'll need to break the string into an array based on the seperator before calling this, string.Split() will do the job.

You could use the File.WriteAllLines method:

public class Program
{
    static void Main(string[] args)
    {
        File.WriteAllLines(
            args[0], 
            args[1].Split(new [] { '|' }, StringSplitOptions.RemoveEmptyEntries)
        );
    }
}

And then call: someFile.exe "fileName" "string|string|string|"

Answer 3

I'd just loop through it and call StreamWriter.WriteLine.

Answer 4

Can you explain what you mean by "The file name will be dynamic enough that the .exe will know what string goes where"?

Also, you say you want new and "fun" ways. So what are the old and boring ones you've already thought of? :-)
