In the following example, a StreamWriter writes two lines of text to a file, and then a StreamReader reads the file back:
using System;
using System.IO;
using System.Linq;
class Program
{
static void Main()
{
using (FileStream fs = File.Create("test.txt"))
using (TextWriter writer = new StreamWriter(fs))
{
writer.WriteLine("Line1");
writer.WriteLine("Line2");
}
using (FileStream fs = File.OpenRead("test.txt"))
using (TextReader reader = new StreamReader(fs))
{
Console.WriteLine(reader.ReadLine()); // Line1
Console.WriteLine(reader.ReadLine()); // Line2
}
}
}
