在 C# 中重命名目录

问题描述

我在任何地方都找不到 DirectoryInfo.Rename(To) 或 FileInfo.Rename(To) 方法.所以，我写了我自己的，我把它张贴在这里供任何人使用，如果他们需要它，因为让我们面对现实:MoveTo 方法是矫枉过正的，如果你只想重命名一个目录或文件，它总是需要额外的逻辑:

I couldn't find a DirectoryInfo.Rename(To) or FileInfo.Rename(To) method anywhere. So, I wrote my own and I'm posting it here for anybody to use if they need it, because let's face it : the MoveTo methods are overkill and will always require extra logic if you just want to rename a directory or file :

public static class DirectoryExtensions
{
    public static void RenameTo(this DirectoryInfo di, string name)
    {
        if (di == null)
        {
            throw new ArgumentNullException("di", "Directory info to rename cannot be null");
        }

        if (string.IsNullOrWhiteSpace(name))
        {
            throw new ArgumentException("New name cannot be null or blank", "name");
        }

        di.MoveTo(Path.Combine(di.Parent.FullName, name));

        return; //done
    }
}

推荐答案

移动和重命名没有区别；你应该简单地调用 Directory.Move.

There is no difference between moving and renaming; you should simply call Directory.Move.

一般来说，如果你只做一个操作，你应该使用 File 和 Directory 类中的 static 方法代替创建 FileInfo 和 DirectoryInfo 对象.

In general, if you're only doing a single operation, you should use the static methods in the File and Directory classes instead of creating FileInfo and DirectoryInfo objects.
