示例1: Main
//引入命名空间
using System;
using System.IO;
class Test
{
public static void Main()
{
string path = @"c:\temp\MyTest.txt";
FileInfo fi1 = new FileInfo(path);
if (!fi1.Exists)
{
//Create a file to write to.
using (StreamWriter sw = fi1.CreateText())
{
sw.WriteLine("Hello");
sw.WriteLine("And");
sw.WriteLine("Welcome");
}
}
//Open the file to read from.
using (StreamReader sr = fi1.OpenText())
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(s);
}
}
try
{
string path2 = path + "temp";
FileInfo fi2 = new FileInfo(path2);
//Ensure that the target does not exist.
fi2.Delete();
//Copy the file.
fi1.CopyTo(path2);
Console.WriteLine("{0} was copied to {1}.", path, path2);
//Delete the newly created file.
fi2.Delete();
Console.WriteLine("{0} was successfully deleted.", path2);
}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}

}
//This code produces output similar to the following;
//results may vary based on the computer/file structure/etc.:
//
//Hello
//And
//Welcome
//c:\MyTest.txt was copied to c:\MyTest.txttemp.
//c:\MyTest.txttemp was successfully deleted.示例2: Main
//引入命名空间
using System;
using System.IO;
public class FileInfoMainTest
{
public static void Main()
{
// Open an existing file, or create a new one.
FileInfo fi = new FileInfo("temp.txt");
// Create a writer, ready to add entries to the file.
StreamWriter sw = fi.AppendText();
sw.WriteLine("This is a new entry to add to the file");
sw.WriteLine("This is yet another line to add...");
sw.Flush();
sw.Close();
// Get the information out of the file and display it.
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...
//Add another line to the output...
//This is a new entry to add to the file
