application and the underlying operating system. To improve the reliability of the platform and to achieve the level of stability required for transaction-oriented e-business applications, the CLR is also responsible for some other tasks, such as monitoring the operation of the program. According to. NET, the program that runs under CLR monitoring is a "managed" (managed) code, not an application or component that is not under the CLR, that runs directly on bare metal, or that is "unmanaged" (

(); Write your own code here } finally { sqliteconn.getinstance (). Releaseconn (); } It is noteworthy that each time the connection is requested, it must be released using the Releaseconn method, otherwise the other threads will no longer be connected. For security purposes, the most restrictive read-write lock restrictions (that is, unreadable when writing) are enabled in the tool class written by the author. If the data is read frequently, readers can also develop a method of get
