Overload resolution failed because no accessible 'New' accepts this number of arguments.

推荐答案

该错误表示所说的内容.你是程序员吗?您是否检查过Document类期望什么参数?我肯定知道您输入的参数数量错误.

The error means what is says. Are you a programmer ? Have you checked what arguments the Document class expects ? I know for sure you have the wrong number of arguments.

从异常来看，这仅意味着您需要检查该行上的参数数量.

Judging from the exception, it simply means that you need to check on the number of arguments on that line. Probably a Google[^] on the error might help.
