c#如何给文件或文件夹重命名

如题,我看在C#文件操作里有很多,比如Create,delete呀,唯独就是没有重命名的file.rename,想给文件重命名怎么办呢?难道非要先COPY一下再起一个名字吗?

Answer 1

用file.move

原形：
public static void Move (
string sourceFileName,
string destFileName
)
参数
sourceFileName
要移动的文件的名称。
destFileName
文件的新路径。

using System;
using System.IO;

class Test
{
public static void Main()
{
string path = @"c:\temp\MyTest.txt";
string path2 = @"c:\temp2\MyTest.txt";
try
{
if (!File.Exists(path))
{
// This statement ensures that the file is created,
// but the handle is not kept.
using (FileStream fs = File.Create(path)) {}
}

// Ensure that the target does not exist.
if (File.Exists(path2))
File.Delete(path2);

// Move the file.
File.Move(path, path2);
Console.WriteLine("{0} was moved to {1}.", path, path2);

// See if the original exists now.
if (File.Exists(path))
{
Console.WriteLine("The original file still exists, which is unexpected.");
}
else
{
Console.WriteLine("The original file no longer exists, which is expected.");
}

}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
}
}
