导致此构建错误的原因是什么？
类型' AriaLibrary.AriaBL.Book '中
'I:\编程\ MyProgram \图书馆\ AriaNetDelijanCorporation\AriaLibrary\AriaBL\AriaBL.cs'
与导入类型冲突
'AriaLibrary.AriaBL.Book'中
'I:\编程\ MyProgram \图书馆\ AriaNetDelijanCorporation\AriaLibrary\BIN \调试\ AriaLibrary.exe'.
使用'I:\ Programing\MyProgram\Library\AriaNetDelijanCorporation\AriaLibrary\AriaBL\AriaBL.cs'中定义的类型.
我:\编程\ MyProgram\Library\AriaNetDelijanCorporation\AriaLibrary\UI\Document\Book\frm_AddNewBookISO.cs 24 16 AriaLibrary
