推荐答案

你必须使用递归方法来计算当前文件夹中每个文件的大小，并为每个子文件夹调用相同的方法。



在此方法中查找当前文件夹的子项，您应该使用Directory.GetDirectories（）方法，并查找可以使用的文件大小FileInfo类（这两个类都来自System.IO名称空间）。

You have to use a recursive method that calculate the size of each file from the current folder and invoke the same method for each subfolder.

In this method to find the sub-items of the current folder you should use Directory.GetDirectories() method, and to find the size of a file you can use FileInfo class (both classes are from System.IO namespace).

使用此方法获取所有文件名： http://msdn.microsoft.com/en-us/library/ms143316%28v=vs.110%29.aspx [< a href =http://msdn.microsoft.com/en-us/library/ms143316%28v=vs.110%29.aspxtarget =_ blanktitle =New Window> ^ ] 。



您不需要自己使用递归;此方法允许您获取目录中的所有文件。使用 SearchOption.AllDirectories ：

http://msdn.microsoft.com/en-us/library/ms143448%28v=vs.110%29.aspx [ ^ ]。



您需要的大小将是所有文件大小的总和。这是你如何获得每个文件的大小：

http://msdn.microsoft.com/en-us/library/system.io.fileinfo.length%28v=vs.110%29.aspx [<一个href =http://msdn.microsoft.com/en-us/library/system.io.fileinfo.length%28v=vs.110%29.aspxtarget =_ blanktitle =New Window> ^ ]，

http://msdn.microsoft.com/en-us/library/System.IO.FileInfo%28v=vs.110%29.aspx [ ^ ]。

Use this method to get all file names: http://msdn.microsoft.com/en-us/library/ms143316%28v=vs.110%29.aspx[^].

You don't need to use recursion by yourself; this method allows you to get all files in the directory. Use SearchOption.AllDirectories:
http://msdn.microsoft.com/en-us/library/ms143448%28v=vs.110%29.aspx[^].

The size you need will be the sum of the sizes of all files. This is how you can get the size for each file:
http://msdn.microsoft.com/en-us/library/system.io.fileinfo.length%28v=vs.110%29.aspx[^],
http://msdn.microsoft.com/en-us/library/System.IO.FileInfo%28v=vs.110%29.aspx[^].
