}
catch (System.IO.IOException ex)
{
   Console.WriteLine(ex.Message); 
}

请帮我怎么做？

推荐答案

您无法删除该文件的原因很充分。假设一个会计流程正在忙于从文件中读取以创建分类帐条目，并且您从其下方取出文件 - 突然之间分类帐将无法平衡。在这种情况下，Windows试图保护您。



如果您必须删除该文件，理论上您可以发出 DEL文件名命令（相当于在命令提示符下调用DEL）通过 Process.Start 。另一种方法是使用一个涉及大量p /调用的更复杂的过程来杀死文件上的锁。

You can't delete the file for very good reasons. Suppose that an accounting process is busy reading from the file to create ledger entries and you take the file out from underneath them - all of a sudden the ledger will not balance. In this case, Windows is trying to protect you.

If you must delete the file, then theoretically you could issue a DEL filename command (the equivalent of calling DEL at the command prompt) through Process.Start. The alternative is to kill the lock on the file using a much more complex process which involves a lot of p/invoking.

你做不到。当文件打开时，它被os锁定。你不能重命名，删除，移动该文件。据我了解，使用后不要关闭该文件。第一个关闭文件及其所有引用，然后你可以删除它。

you cannot. when a file is open, it is locked by os. you cannot rename, delete, move that file. As I understand, you don't close that file after using it. first close file and all references to it, then you can delete it.

你不能删除这些文件，但你可以照顾它。请参阅我过去的回答：

You cannot delete such files, but you can take care about it. Please see my past answer:
