在C＃中重命名目录

问题描述

在任何地方找不到DirectoryInfo.Rename（To）或FileInfo.Rename（To）方法。所以，我写了我自己的，我发布在这里供任何人使用，如果他们需要它，因为我们面对它：MoveTo方法是overkill，如果你只想重命名一个目录或文件将永远需要额外的逻辑： / p>

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

移动和重命名之间没有区别;您应该直接致电。

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 static code>文件和目录类而不是创建 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.
