First solution Avoid System.IO.File.Move solutions posted here (marked answer included). It fails over networks. However, copy/delete pattern works locally and over networks. Follow one of the move solutions, but replace it with Copy instead. Then use File.Delete to delete the original file. You can create a Rename method to simplify it. Ease of use Use the VB assembly in C#. Add reference to Microsoft.VisualBasic Then to rename the file: Microsoft.VisualBasic.FileIO.FileSystem.RenameFile(myfile, newName); Both are strings. Note that myfile has the full path. newName does not. For example: a = "C:\whatever\a.txt"; b = "b.txt"; Microsoft.VisualBasic.FileIO.FileSystem.RenameFile(a, b); The C:\whatever\ folder will now contain b.txt.

添加:

namespace System.IO
{
    public static class ExtendedMethod
    {
        public static void Rename(this FileInfo fileInfo, string newName)
        {
            fileInfo.MoveTo(fileInfo.Directory.FullName + "\\" + newName);
        }
    }
}

然后……

FileInfo file = new FileInfo("c:\test.txt");
file.Rename("test2.txt");

我遇到过一种情况，当我不得不在事件处理程序中重命名文件时，它会触发任何文件更改，包括重命名，并且要跳过永远重命名我必须重命名的文件，使用:

创建副本 移除原始的

File.Copy(fileFullPath, destFileName); // Both have the format of "D:\..\..\myFile.ext"
Thread.Sleep(100); // Wait for the OS to unfocus the file
File.Delete(fileFullPath);

注意:在这个示例代码中，我们打开一个目录并搜索PDF文件，文件名中包含开括号和闭括号。您可以检查和替换名称中的任何字符，或者使用替换函数指定一个全新的名称。

从这段代码中还可以使用其他方法来进行更详细的重命名，但我的主要目的是展示如何使用File。移动做批量重命名。当我在我的笔记本电脑上运行它时，它可以处理180个目录中的335个PDF文件。这是一时兴起的代码，还有更详细的方法来实现它。

namespace BatchRenamer
{
    class Program
    {
        static void Main(string[] args)
        {
            var dirnames = Directory.GetDirectories(@"C:\the full directory path of files to rename goes here");

            int i = 0;

            try
            {
                foreach (var dir in dirnames)
                {
                    var fnames = Directory.GetFiles(dir, "*.pdf").Select(Path.GetFileName);

                    DirectoryInfo d = new DirectoryInfo(dir);
                    FileInfo[] finfo = d.GetFiles("*.pdf");

                    foreach (var f in fnames)
                    {
                        i++;
                        Console.WriteLine("The number of the file being renamed is: {0}", i);

                        if (!File.Exists(Path.Combine(dir, f.ToString().Replace("(", "").Replace(")", ""))))
                        {
                            File.Move(Path.Combine(dir, f), Path.Combine(dir, f.ToString().Replace("(", "").Replace(")", "")));
                        }
                        else
                        {
                            Console.WriteLine("The file you are attempting to rename already exists! The file path is {0}.", dir);
                            foreach (FileInfo fi in finfo)
                            {
                                Console.WriteLine("The file modify date is: {0} ", File.GetLastWriteTime(dir));
                            }
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            Console.Read();
        }
    }
}

我找不到适合我的方法，所以我提出了我的版本。当然，它需要输入和错误处理。

public void Rename(string filePath, string newFileName)
{
    var newFilePath = Path.Combine(Path.GetDirectoryName(filePath), newFileName + Path.GetExtension(filePath));
    System.IO.File.Move(filePath, newFilePath);
}

System.IO.File.Move(oldNameFullPath, newNameFullPath);
