我维护的项目有一组usercontrols，其中SPWeb和SPSite对象在SPContext的构造函数中初始化。然后将这些对象传递给其他类

public MyUserControl : UserControl
{  
private SPWeb web;
public MyUserControl() { web = SPContext.Current.Web; }
AnotherClass.SomeMethod ( web );
}

日志中包含以下两个条目：

(一)

(二)

在此线程结束之前未释放SPRequest对象。为避免浪费系统资源，请在使用完此对象或其父对象（如SPSite或SPWeb）后立即将其丢弃。现在将处理此对象。分配Id:{444DCA1-C2F6-493D-9D02-D04F75C6E384}已分配此SPRequest

An SPRequest object was not disposed before the end of this thread.  To avoid wasting system resources, dispose of this object or its parent (such as an SPSite or SPWeb) as soon as you are done using it.  This object will now be disposed.
