C# Text File and Arrays

email me

Using Visual Studio 2015, I selected File–New–Project–Visual C#–Console Application, and began testing text file creation, writing and reading, loading items from the text file into an array, and returning specific elements¬†from the array.

using System;
using System.IO;
class Test
{
public static void Main()
{
string path = @"c:\CSharpLabs\computers.txt";

// See if file exists, if not exists, create file
if (!File.Exists(path))

{
// Create a file to write to.
string[] createText = { "computer1", "computer2", "computer3" };
File.WriteAllLines(path, createText);
}

// Append to last line
string appendText = "computer99" + Environment.NewLine;
File.AppendAllText(path, appendText);

// Read each line
string[] readText = File.ReadAllLines(path);
foreach (string s in readText)

{
//output to screen
Console.WriteLine(s);
}

//select a couple of array items to output
Console.WriteLine("Array 1 is: {0}", readText[0]);
Console.WriteLine("Array 2 is: {0}", readText[1]);
Console.ReadLine();
}
}
