Renaming a directory in C#
提问by Alex Marshall
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 :
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：
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
}
}

There is no difference between moving and renaming; you should simply call Directory.Move.
移动和重命名没有区别；你应该简单地调用Directory.Move.
In general, if you're only doing a single operation, you should use the staticmethods in the Fileand Directoryclasses instead of creating FileInfoand DirectoryInfoobjects.
一般来说，如果你只做一个操作，你应该使用and类中的static方法，而不是创建and对象。FileDirectoryFileInfoDirectoryInfo

You should move it:
你应该移动它：
Directory.Move(source, destination);

One already exists. If you cannot get over the "Move" syntax of the System.IOnamespace. There is a static class FileSystemwithin the Microsoft.VisualBasic.FileIOnamespace that has both a RenameDirectoryand RenameFilealready within it.
一个已经存在。如果您无法克服System.IO命名空间的“移动”语法。有一个静态类FileSystem的内Microsoft.VisualBasic.FileIO同时具有一个命名空间RenameDirectory，并RenameFile在其中了。
As mentioned by SLaks, this is just a wrapper for Directory.Moveand File.Move.
正如 SLaks 所提到的，这只是Directory.Moveand的包装器File.Move。
