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);

public void RenameFile(string filePath, string newName)
{
    FileInfo fileInfo = new FileInfo(filePath);
    fileInfo.MoveTo(fileInfo.Directory.FullName + "\\" + newName);
}

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

看一下System.IO.File。移动，“移动”文件到一个新名称。

System.IO.File.Move("oldfilename", "newfilename");

您可以使用File。行动起来吧。

private static void Rename_File(string FileFullPath, string NewName) // nes name without directory actualy you can simply rename with fileinfo.MoveTo(Fullpathwithnameandextension);
        {
            FileInfo fileInfo = new FileInfo(FileFullPath);
            string DirectoryRoot = Directory.GetParent(FileFullPath).FullName;

            string filecreator = FileFullPath.Substring(DirectoryRoot.Length,FileFullPath.Length-DirectoryRoot.Length);
             
            filecreator = DirectoryRoot + NewName;
            try
            {
                fileInfo.MoveTo(filecreator);
            }
            catch(Exception ex)
            {
                Console.WriteLine(filecreator);
                Console.WriteLine(ex.Message);
                Console.ReadKey();
            }

    enter code here
            // string FileDirectory = Directory.GetDirectoryRoot()

        }
