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);
}

Use:

using System.IO;

string oldFilePath = @"C:\OldFile.txt"; // Full path of old file
string newFilePath = @"C:\NewFile.txt"; // Full path of new file

if (File.Exists(newFilePath))
{
    File.Delete(newFilePath);
}
File.Move(oldFilePath, newFilePath);

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.

当c#没有某些特性时，我就用c++或C:

public partial class Program
{
    [DllImport("msvcrt", CallingConvention = CallingConvention.Cdecl, SetLastError = true)]
    public static extern int rename(
            [MarshalAs(UnmanagedType.LPStr)]
            string oldpath,
            [MarshalAs(UnmanagedType.LPStr)]
            string newpath);

    static void FileRename()
    {
        while (true)
        {
            Console.Clear();
            Console.Write("Enter a folder name: ");
            string dir = Console.ReadLine().Trim('\\') + "\\";
            if (string.IsNullOrWhiteSpace(dir))
                break;
            if (!Directory.Exists(dir))
            {
                Console.WriteLine("{0} does not exist", dir);
                continue;
            }
            string[] files = Directory.GetFiles(dir, "*.mp3");

            for (int i = 0; i < files.Length; i++)
            {
                string oldName = Path.GetFileName(files[i]);
                int pos = oldName.IndexOfAny(new char[] { '0', '1', '2' });
                if (pos == 0)
                    continue;

                string newName = oldName.Substring(pos);
                int res = rename(files[i], dir + newName);
            }
        }
        Console.WriteLine("\n\t\tPress any key to go to main menu\n");
        Console.ReadKey(true);
    }
}

public static class ImageRename
{
    public static void ApplyChanges(string fileUrl,
                                    string temporaryImageName,
                                    string permanentImageName)
    {
        var currentFileName = Path.Combine(fileUrl,
                                           temporaryImageName);

        if (!File.Exists(currentFileName))
            throw new FileNotFoundException();

        var extention = Path.GetExtension(temporaryImageName);
        var newFileName = Path.Combine(fileUrl,
                                       $"{permanentImageName}
                                         {extention}");

        if (File.Exists(newFileName))
            File.Delete(newFileName);

        File.Move(currentFileName, newFileName);
    }
}

您可以使用File。行动起来吧。
