管理对象以便正确进行处理。使用 SPWeb 或 SPSite 等对象可能会耗用大量内存，而且在 Windows PowerShell 脚本中使用这些对象需要正确管理内存。通过使用 SPAssignment 对象，可以将对象分配给变量，然后在不需要这些对象时对它们进行处理，以释放内存。在使用 SPWeb 、 SPSite 或 SPSiteAdministration 对象时，如果不使用分配集合或 Global 参数，则会自动处理这些对象。 备注 在使用 Global 参数时，所有对象均包含在全局存储中。如果未立即使用对象，或未通过使用 Stop-SPAssignment 命令来处理对象，则可能会发生内存不足的情况。 |
