注意:在这个示例代码中,我们打开一个目录,搜索文件名中带有左括号和右括号的PDF文件。可以检查并替换名称中的任何字符,也可以使用替换函数指定一个全新的名称
从这段代码还有其他方法可以进行更精细的重命名,但我的主要目的是演示如何使用File.Move进行批量重命名。当我在笔记本电脑上运行它时,它对180个目录中的335个PDF文件有效。这是一时冲动的代码,有更详细的方法可以做到这一点

在File.Move方法中,如果文件已经存在,则不会覆盖该文件。它将抛出一个异常 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环绕它以避免出现异常。只需添加:
namespace System.IO
{
public static class FileInfoExtensions
{
public static void Rename(this FileInfo fileInfo, string newName)
{
fileInfo.MoveTo(Path.Combine(fileInfo.Directory.FullName, newName));
}
}
}
然后
FileInfo file = new FileInfo("c:\test.txt");
file.Rename("test2.txt");
使用:
System.IO.File.Move
解决方案张贴在此处(包括带标记的答案)。
它通过网络发生故障。然而,复制/删除模式在本地和网络上工作。遵循其中一种移动解决方案,但将其替换为“复制”。然后使用File.Delete删除原始文件
您可以创建一个重命名方法来简化它Microsoft.VisualBasic.FileIO.FileSystem.RenameFile(myfile,newName)代码>
两者都是字符串。请注意,myfile具有完整路径。newName没有。
例如:
a = "C:\whatever\a.txt";
b = "b.txt";
Microsoft.VisualBasic.FileIO.FileSystem.RenameFile(a, b);
C:\which\
文件夹现在将包含b.txt
您可以将其复制为新文件,然后使用
System.IO.file
类删除旧文件:
if (File.Exists(oldName))
{
File.Copy(oldName, newName, true);
File.Delete(oldName);
}
Move正在执行相同的操作=复制并删除旧的
