sharepoint 查询calendar recurrence

多的不说了，贴代码

<Where>

  <DateRangesOverlap>

    <FieldRef Name='StartDate' />

    <FieldRef Name='EndDate' />

    <Value Type='DateTime'>

      <Month />

    </Value>

  </DateRangesOverlap>

</Where>

查询方式

SPQuery query = new SPQuery();
                    query.ExpandRecurrence = true;
                    query.CalendarDate = DateTime.Now;

string caml = string.Format(@"<Where> 
  <DateRangesOverlap>  
            <FieldRef Name='EventDate' />  
            <FieldRef Name='EndDate' />  
            <FieldRef Name='RecurrenceID' />  
            <Value Type='DateTime' IncludeTimeValue='TRUE'>  
                <Month />  
            </Value>  
        </DateRangesOverlap>    
</Where>");

里面的条件可以为Today,Week,Month
