Answer 1

First you have to create an string array with your data then you can write it to the txt file

string[] lines = { "First line", "Second line", "Third line" };

WriteAllLines creates a file, writes a collection of strings to the file,and then closes the file.

System.IO.File.WriteAllLines(@"C:\Users\Public\TestFolder\WriteLines.txt",lines);

Answer 2

Refer to System.IO.File

And this may be a quick help:

using System;
public class Test
{
    public static void Main()
    {
        String Str = "";

        for(int i =0;i<10;i++)
        {
            Str += i.ToString();
        }
        Console.WriteLine(Str);
        System.IO.File.WriteAllText(@"C:\SaveInfo.Txt",Str);
    }
}
