如何在Windows中以编程方式关闭打开的文件/应用程序？

Question

I am writing data to a csv file as result of operation. Than I open the file in excel to examine the data. Often time I forget to close the file in excel and the next operation can't write to the same file. It looks very difficult if not impossible but is there a way I can programmatically close the file (=application that is using the file) before I write to it?

I guess the first thing will be to determine which application is using the file and then shutdown that app? Maybe someone has written a class for this or something?

Answer 1

Okay, per the comments:

Flag the file as ReadOnly in the first operation. Then you can launch Excel and prevent it from getting an opportunistic lock on the file. You can still update the file in subsequent operations by either removing the RO attribute, or using the -Force switch when you write the updates.
