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。

            int i = 0;

            try
            {
                foreach (var dir in dirnames)

                    DirectoryInfo d = new DirectoryInfo(dir);

                    foreach (var f in fnames)

                            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();
        }
    }
}

看一下System.IO.File。移动，“移动”文件到一个新名称。

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

在文件中。方法，这将不会覆盖文件，如果它已经存在。它会抛出一个异常。

所以我们需要检查文件是否存在。

/* Delete the file if exists, else no exception thrown. */

File.Delete(newFileName); // Delete the existing file if exists
File.Move(oldFileName,newFileName); // Rename the oldFileName into newFileName

或者用try catch将其包围以避免异常。

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

您可以使用File。行动起来吧。

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.
