SharePoint中的时间问题

 

CAML

 

items due before 15 days after today.

<SharePoint:SPDataSource

   ...

   selectcommand="<View><Query>

   <OrderBy><FieldRef Name='Date_Due' Ascending='TRUE'/></OrderBy>

   <Where><Leq><FieldRef Name='Date_Due'/><Value Type='DateTime'><Today OffsetDays='15'/></Value>

   </Leq></Where></Query></View>" 

   ...

[Today+3Day(s)]对时间的筛选

     caml查询的时候默认是不精确匹配时间的，需要加上一个属性，就是
IncludeTimeValue='true'
使得caml查询变成

 

 

< Where >
                                           
                                               < Eq >
                                                 < FieldRef Name = ' _ModerationStatus '   />
                                                 < Value Type = ' ModStat ' > 已批准 Value>
                                              Eq>
                                              <Leq>
                                                 <FieldRef Name='" + list.Fields["公告发布时间"].InternalName + @"' />
                                                 <Value Type='DateTime' IncludeTimeValue='true'>" + DateTime.Now.ToString() + @"Z Value>
                                               Leq>
                                            
                                        Where>

 

 

这样再查询的话，就是精确匹配时间的查询了。

 

在页面的时间栏中填写的时间如果是
2008-8-8 0：00
然后保存页面，用程序访问刚才的列表项，然后显示刚才的时间，却显示为2008-8-8 8：00.
刚开始我也很是奇怪呢，后来才发现，估计是时区在作怪，sharepoint内部存储时间都是用那个什么格陵时间吧，可能是为了统一。然后在页面显示的时候才显示为本地时间。

用下面的函数可以转化本地时间为标准时间
DateTime.Now.ToUniversalTime().ToString()

还有就是容易搞混的
8月24号的24：00就是8月25号的0：00
这个问题把我弄混好多次了，几乎每次都中招。

下面的代码是处理过期的新闻测试代码，在sharepoint中的过期新闻，被我从“页面（Pages）”列表库移动到了“过期新闻（DocLib）”列表库
