解决方法：D:\Program Files\ArcGIS\Bin\AppLockMgr.exe exe扩展名改为rrg，重新打开arcmap就可以了。
The AppLockMgr coclass is used to control locks on shapefiles and coverages, so no two users can make changes to the
same dataset. It is pretty much the same idea as with relational database抯 lock to prevent multiple users from
making conflicting modifications to a set of data. Lock types are specified by esriLockMgrType enumerator.
