示例1: Main
//引入命名空间
using System;
using System.IO;
class Test
{
public static void Main()
{
string path = Path.GetTempFileName();
var fi1 = new FileInfo(path);
// 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())
{
var s = "";
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(s);
}
}
try
{
string path2 = Path.GetTempFileName();
var fi2 = new FileInfo(path2);
// Ensure that the target does not exist.
fi2.Delete();
// Copy the file.
fi1.CopyTo(path2);
Console.WriteLine($"{path} was copied to {path2}.");
// Delete the newly created file.
fi2.Delete();
Console.WriteLine($"{path2} was successfully deleted.");
}
catch (Exception e)
{
Console.WriteLine($"The process failed: {e.ToString()}");
}
}
}示例2: new FileInfo(String fileName)
//引入命名空间
using System;
using System.IO;
