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);

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.

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()

        }

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);
}

// Source file to be renamed  
string sourceFile = @"C:\Temp\MaheshChand.jpg";  
// Create a FileInfo  
System.IO.FileInfo fi = new System.IO.FileInfo(sourceFile);  
// Check if file is there  
if (fi.Exists)  
{  
// Move file with a new name. Hence renamed.  
fi.MoveTo(@"C:\Temp\Mahesh.jpg");  
Console.WriteLine("File Renamed.");  
}
