我正尝试使用ExchangeServiceBinding从Outlook日历中读取约会，但我的解决方案只从"默认"Outlook日历中获取约会，而不从"子日历/自定义日历"中读取。你们知道如何定义其余的日历吗？或者你们知道包含所有日历的更好的解决方案吗？
关键的部分是，解决方案不应该包含MAPI，因为下次在web服务中使用。
我当前的代码：
private static List<List<string>> ReadCalendarEvents(string email)
{
List<List<string>> calendarEvents = new List<List<string>>();
// Specify the request version.
esb.RequestServerVersionValue = new RequestServerVersion();
esb.RequestServerVersionValue.Version = ExchangeVersionType.Exchange2007;
// Form the FindItem request.
FindItemType findItemRequest = new FindItemType();
CalendarViewType calendarView = new CalendarViewType();
calendarView.StartDate = DateTime.Now.AddDays(-7);
calendarView.EndDate = DateTime.Now.AddDays(200);
calendarView.MaxEntriesReturned = 1000;
calendarView.MaxEntriesReturnedSpecified = true;
findItemRequest.Item = calendarView;
// Define which item properties are returned in the response.
ItemResponseShapeType itemProperties = new ItemResponseShapeType();
// Use the Default shape for the response.
//itemProperties.BaseShape = DefaultShapeNamesType.IdOnly;
itemProperties.BaseShape = DefaultShapeNamesType.AllProperties;
findItemRequest.ItemShape = itemProperties;
DistinguishedFolderIdType[] folderIDArray = new DistinguishedFolderIdType[1];
folderIDArray[0] = new DistinguishedFolderIdType();
folderIDArray[0].Id = DistinguishedFolderIdNameType.calendar;
//
folderIDArray[0].Mailbox = new EmailAddressType();
folderIDArray[0].Mailbox.EmailAddress = email;
findItemRequest.ParentFolderIds = folderIDArray;
// Define the traversal type.
findItemRequest.Traversal = ItemQueryTraversalType.Shallow;
try
{
// Send the FindItem request and get the response.
FindItemResponseType findItemResponse = esb.FindItem(findItemRequest);
// Access the response message.
ArrayOfResponseMessagesType responseMessages = findItemResponse.ResponseMessages;
ResponseMessageType[] rmta = responseMessages.Items;
int folderNumber = 0;
foreach (ResponseMessageType rmt in rmta)
{
// One FindItemResponseMessageType per folder searched.
FindItemResponseMessageType firmt = rmt as FindItemResponseMessageType;
if (firmt.RootFolder == null)
continue;
FindItemParentType fipt = firmt.RootFolder;
object obj = fipt.Item;
// FindItem contains an array of items.
if (obj is ArrayOfRealItemsType)
{
ArrayOfRealItemsType items =
(obj as ArrayOfRealItemsType);
if (items.Items == null)
{
folderNumber++;
}
else
{
foreach (ItemType it in items.Items)
{
if (it is CalendarItemType)
{
CalendarItemType cal = (CalendarItemType)it;
List<string> ce = new List<string>();
ce.Add(cal.Location);
ce.Add(cal.Start.ToShortDateString() + " " + cal.Start.ToShortTimeString());
ce.Add(cal.End.ToShortDateString() + " " + cal.End.ToShortTimeString());
ce.Add(cal.Subject);
if (cal.Organizer != null)
{
ce.Add(cal.Organizer.Item.Name);
}
calendarEvents.Add(ce);
Console.WriteLine(cal.Subject + " " + cal.Start.ToShortDateString() + " " + cal.Start.ToShortTimeString() + " " + cal.Location);
}
}
folderNumber++;
}
}
}
}
catch (Exception e)
{
throw;
}
finally
{
}
return calendarEvents;
}
在EWS中，您需要一次查询一个文件夹，对于非默认文件夹，您首先需要找到FolderId，然后才能查询文件夹中的约会（或项目）。要查找邮箱中的所有日历文件夹，您需要使用FindFolder操作并创建一个限制，以将结果限制为FolderClass为IPF的文件夹。约会，例如
// Create the request and specify the travesal type.
FindFolderType findFolderRequest = new FindFolderType();
findFolderRequest.Traversal = FolderQueryTraversalType.Deep;
// Define the properties that are returned in the response.
FolderResponseShapeType responseShape = new FolderResponseShapeType();
responseShape.BaseShape = DefaultShapeNamesType.Default;
findFolderRequest.FolderShape = responseShape;
// Identify which folders to search.
DistinguishedFolderIdType[] folderIDArray = new DistinguishedFolderIdType[1];
folderIDArray[0] = new DistinguishedFolderIdType();
folderIDArray[0].Id = DistinguishedFolderIdNameType.msgfolderroot;
IsEqualToType iet = new IsEqualToType();
PathToUnindexedFieldType FolderClass = new PathToUnindexedFieldType();
FolderClass.FieldURI = UnindexedFieldURIType.folderFolderClass;
iet.Item = FolderClass;
FieldURIOrConstantType constantType = new FieldURIOrConstantType();
ConstantValueType constantValueType = new ConstantValueType();
constantValueType.Value = "IPF.Appointment";
constantType.Item = constantValueType;
iet.FieldURIOrConstant = constantType;
// Add the folders to search to the request.
RestrictionType restriction = new RestrictionType();
restriction.Item = iet;
findFolderRequest.Restriction = restriction;
findFolderRequest.ParentFolderIds = folderIDArray;
try
{
// Send the request and get the response.
FindFolderResponseType findFolderResponse = esb.FindFolder(findFolderRequest);
// Get the response messages.
ResponseMessageType[] rmta = findFolderResponse.ResponseMessages.Items;
foreach (ResponseMessageType rmt in rmta)
{
// Cast to the correct response message type.
if (((FindFolderResponseMessageType)rmt).ResponseClass == ResponseClassType.Success) {
foreach (FolderType folder in ((FindFolderResponseMessageType)rmt).RootFolder.Folders) {
Console.WriteLine(folder.DisplayName);
}
}
}
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
您可能还想考虑使用EWS托管API，这将大大节省您编写所需的时间和代码量
