示例1: Main
//引入命名空間
using System;
using System.IO;
class Test
{
public static void Main()
{
FileInfo fi = new FileInfo(@"c:\MyTest.txt");
// This text is added only once to the file.
if (!fi.Exists)
{
//Create a file to write to.
using (StreamWriter sw = fi.CreateText())
{
sw.WriteLine("Hello");
sw.WriteLine("And");
sw.WriteLine("Welcome");
}
}
// This text will always be added, making the file longer over time
// if it is not deleted.
using (StreamWriter sw = fi.AppendText())
{
sw.WriteLine("This");
sw.WriteLine("is Extra");
sw.WriteLine("Text");
}
//Open the file to read from.
using (StreamReader sr = fi.OpenText())
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(s);
}
}
}
}
//This code produces output similar to the following;
//results may vary based on the computer/file structure/etc.:
//
//Hello
//And
//Welcome
//This
//is Extra
//Text輸出：
Hello And Welcome This is Extra Text This is Extra Text
示例2: Main
//引入命名空間
using System;
using System.IO;
public class AppendTextTest
{
public static void Main()
{
FileInfo fi = new FileInfo("temp.txt");
// Create a writer, ready to add entries to the file.
StreamWriter sw = fi.AppendText();
sw.WriteLine("Add as many lines as you like...");
sw.WriteLine("Add another line to the output...");
sw.Flush();
sw.Close();
// Get the information out of the file and display it.
// Remember that the file might have other lines if it already existed.
StreamReader sr = new StreamReader(fi.OpenRead());
while (sr.Peek() != -1)
Console.WriteLine( sr.ReadLine() );
}
}
//This code produces output similar to the following;
//results may vary based on the computer/file structure/etc.:
//Add as many lines as you like...
