如何检查是否System.IO.File.Delete删除的文件成功地 [英] How to check if System.IO.File.Delete deleted a file sucessfully

问题描述

删除使用有System.IO.File类文件后：

  System.IO.File.Delete（openedPdfs 
 
 
。路径）; 
  

我需要运行一些代码，如果文件被成功删除。
只要该方法不返回任何值，我如果删除方法后该文件存在检查。如果仍然存在，我认为这次行动失败了。

问题是，删除方法效果很好，但该文件的几秒钟被删除。该存在的函数返回true，因为当时它正在检查该文件是存在的。

我如何验证肯定，如果 System.IO。 ？File.Delete（openedPdfs.path）; 成功地完成了

代码：

  FileInfo的文件=新的FileInfo（openedPdfs.path）; 
 System.IO.File.Delete（openedPdfs.path）; 
如果（file.Exists ==假）
 {...} 
，否则
 {...} 
  

解决方案

删除应该抛出一个异常，如果该文件未删除。因此，您的来电存在是多余的。

有一个看的为删除 。

After removing a file using the system.io.file class:

System.IO.File.Delete(openedPdfs.path);

I need to run some code if the file was sucessfully deleted. As long as the method does not return any value, I am checking if the file exist after the delete method. If it still exist I supposed the operation had failed.

The problem is, the deletion method works fine, but there is a couple of seconds to the file to be deleted. The Exist function return true because at the time it is checking the file is there.

How can I verify for sure if the System.IO.File.Delete(openedPdfs.path); completed sucessfully ?

Code:

FileInfo file = new FileInfo(openedPdfs.path);    
System.IO.File.Delete(openedPdfs.path);
if (file.Exists == false)
{ ... }
else 
{ ... }

解决方案

Delete should throw an exception if the file wasn't deleted. Hence, your call to Exists is redundant.

Have a look at the documentation for Delete.
