對於已經打開的dwg文檔,用下面語句讀取時會出現此錯誤
Dim sourceDB AsNew Autodesk.AutoCAD.DatabaseServices.Database(False, True) sourceDB.ReadDwgFile(dwgFullName, System.IO.FileShare.Read, True, "")
此時只需將語句中的System.IO.FileShare.Read改為System.IO.FileShare.ReadWrite即可,即: sourceDB.ReadDwgFile(dwgFullName, System.IO.FileShare.ReadWrite, True, "")
