c# - FileInfo.MoveTo() 与 File.Move()

Question

这两种移动文件的方法有什么区别吗？

System.IO.FileInfo f = new System.IO.FileInfo(@"c:\foo.txt");
f.MoveTo(@"c:\bar.txt");

//vs

System.IO.File.Move(@"c:\foo.txt", @"c:\bar.txt");

查看此 MSDN 页面中的“备注”部分 http://msdn.microsoft.com/en-us/library/akth6b1k.aspx :

If you are going to reuse an object several times, consider using the instance method of FileInfo instead of the corresponding static methods of the File class, because a security check will not always be necessary.

我认为这种差异在 File (Directory) 和 FileInfo (DirectoryInfo) 类之间最为明显。
