ArcEngine 释放锁

一、使用System.Runtime.InteropServices.Marshal.ReleaseComObject（pCursor）；释放资源。

二、如果第一不行，可以试用第二种：

IWorkspaceFactory pwf = new  ShapefileWorkspaceFactory();

//关闭资源锁定  

IWorkspaceFactoryLockControl ipWsFactoryLock = (IWorkspaceFactoryLockControl)pwf;

if  (ipWsFactoryLock.SchemaLockingEnabled)

{

     ipWsFactoryLock.DisableSchemaLocking();

}
