示例1: Main
//引入命名空间
using System;
using System.IO;
using System.Text;
class Test
{
public static void Main()
{
string path = @"c:\temp\MyTest.txt";
// This text is added only once to the file.
if (!File.Exists(path))
{
// Create a file to write to.
string[] createText = { "Hello", "And", "Welcome" };
File.WriteAllLines(path, createText, Encoding.UTF8);
}
// This text is always added, making the file longer over time
// if it is not deleted.
string appendText = "This is extra text" + Environment.NewLine;
File.AppendAllText(path, appendText, Encoding.UTF8);
// Open the file to read from.
string[] readText = File.ReadAllLines(path, Encoding.UTF8);
foreach (string s in readText)
{
Console.WriteLine(s);
}
}
