采用模拟账号的方式读取日历信息,注意下日历的内容读取(Body)读取。代码如下:(采用 EWS API 2.0版本)
1、读取内容前必须设置如下属性:否则会提示:You must load or assign this property before you can read its value Body
如下:
//*************************以为设置为读取内容,否则会提示:You must load or assign this property before you can read its value Body
PropertySet detailedPropertySet = new PropertySet(BasePropertySet.FirstClassProperties, AppointmentSchema.Recurrence);
service.LoadPropertiesForItems(from Item item in findResults select item, detailedPropertySet);
//******************************
设置后正常。
2、如果想读取内容的纯文本,目前Exchange server2010内的版本支持读取带HTML的内容。调用代码如下:
//如果文本不为空
if (item.TextBody != null)
{
TextBody txtBody = item.TextBody;
//
info.BodyText = txtBody.Text;
}
调用后出现如下错误:
所以只能用正则表达式获取文本内容。
附带正确代码:
#region//读入日历信息 /// <summary> /// 读入日历信息 /// </summary> /// <param name="config">配置参数</param> /// <param name="searchdtStart">开始时间</param> /// <param name="searchdtEnd">结束时间</param> /// <returns>返回列表</returns> private static List<CalendarInfo> GetCalendarList(EwsConfig config,DateTime searchdtStart,DateTime searchdtEnd) { //返回值 List<CalendarInfo> CalendarInfoList = new List<CalendarInfo>(); try { //读取未读邮件 CalendarFolder calendarfolder = (CalendarFolder)Folder.Bind(service, WellKnownFolderName.Calendar); //如果不为空 if (calendarfolder != null) { //检索开始时间和结束时间 CalendarView calendarView = new CalendarView(searchdtStart, searchdtEnd); //检索数据 FindItemsResults<Appointment> findResults = calendarfolder.FindAppointments(calendarView); //*************************以为设置为读取内容,否则会提示:You must load or assign this property before you can read its value Body PropertySet detailedPropertySet = new PropertySet(BasePropertySet.FirstClassProperties, AppointmentSchema.Recurrence); service.LoadPropertiesForItems(from Item item in findResults select item, detailedPropertySet); //****************************** //返回 foreach (Appointment item in findResults.Items) { //实体类 CalendarInfo info = new CalendarInfo(); //主题 info.Identity = item.ICalUid; //来源 info.Source = "Exchange2010"; //主题 info.Subject = item.Subject; //地区 info.Location = item.Location; //开始时间 info.StartTime = item.Start.ToLocalTime(); //结束时间 info.EndTime = item.End.ToLocalTime(); //url info.Url = item.WebClientReadFormQueryString; //加入如下,表示读取内容,否则会提示如下: //HTML如果不为空 if (item.Body != null) { //html格式的内容 MessageBody body = item.Body; //读取文本 info.BodyHtml = body.Text; } // //读取id if (item.Id != null) { info.ItemIdType = new CalendarInfo.CalendarItemIdType { Id = item.Id.UniqueId, ChangeKey = item.Id.ChangeKey }; } //加入到集合中去 CalendarInfoList.Add(info); } } } catch (Microsoft.Exchange.WebServices.Data.ServiceResponseException ex) { throw ex; } //return return CalendarInfoList; } #endregion
