        }

推荐答案

上次检查时，DirectoryInfo类是用'path' - 例如

Last time I checked, the DirectoryInfo class was constructed with a 'path' - eg

DirectoryInfo directoryInfo1 = new DirectoryInfo(@"C:\");

所以我不太确定你要用什么来实现

so Im not quite sure what you are trying to achieve with your

DirectoryInfo directoryInfo1 = new DirectoryInfo(Module1.kb.project);
