Your language is chinese? What does this mean? "System.NullReferenceException: 未将对象引用设置到对象的实例。"

[Martin KJELDSEN]

Can you check if the excel file is somehow locked for writing?

[Wrend.1]

未将对象引用设置到对象的实例 ： The object reference is not set to an instance of the object

[Wrend.1]

It can be writed, I opened it to see if there was any exception, but I didn't find it.

[Wrend.1]

��I couldn't find the reason, and finally spent a lot of time rewriting the program for my project.
