我的任务很简单。我有一个公共文件夹（实际上是一个日历），我需要从两个日期之间拉出所有会议。
我正在使用Visual Studio 2010，ASP.Net 4.0，Microsoft Exchange Server Web服务（EWS）和Exchange Server 2007.
我已成功使用以下代码在个人日历中创建项目：
public static string[] CreateAppointment()
{
// Set up the binding with credentials and URL.
com.webmail.ExchangeServiceBinding binding = new com.webmail.ExchangeServiceBinding();
binding.Credentials = new System.Net.NetworkCredential("steve.kershaw", "mypasswordhere", "domain.com");
binding.Url = @"https://webmail.com/ews/exchange.asmx";
// Creating new appointment item type
com.webmail.CalendarItemType appointment = new com.webmail.CalendarItemType();
// Add properties to the newly created appointment.
appointment.Importance = com.webmail.ImportanceChoicesType.Normal;
appointment.ImportanceSpecified = true;
appointment.ItemClass = "IPM.Appointment";
appointment.Subject = "mySubject";
appointment.Body = new com.webmail.BodyType();
appointment.Body.BodyType1 = com.webmail.BodyTypeType.HTML;
appointment.Body.Value = "<b>Body</b>";
appointment.Categories = new string[] { "Category Red", "Category Blue" };
appointment.Start = new DateTime(2013,4,30,12, 30,0);
appointment.StartSpecified = true;
appointment.End = new DateTime(2013, 4, 30, 13, 0, 0);
appointment.EndSpecified = true;
appointment.IsAllDayEvent = false;
appointment.IsAllDayEventSpecified = true;
appointment.Location = "myOffice";
appointment.LegacyFreeBusyStatus = com.webmail.LegacyFreeBusyType.Busy;
appointment.LegacyFreeBusyStatusSpecified = true;
appointment.ReminderIsSet = true;
appointment.ReminderIsSetSpecified = true;
appointment.ReminderMinutesBeforeStart = "60";
// Specify the destination folder
com.webmail.DistinguishedFolderIdType folder = new com.webmail.DistinguishedFolderIdType();
folder.Id = com.webmail.DistinguishedFolderIdNameType.calendar;
// Create the NonEmptyArrayOfAllItemsType array that will contain the appointment.
com.webmail.NonEmptyArrayOfAllItemsType arrayOfItems = new com.webmail.NonEmptyArrayOfAllItemsType();
arrayOfItems.Items = new com.webmail.ItemType[1];
// Add our appointment to the array.
arrayOfItems.Items[0] = appointment;
// Create the request.
com.webmail.CreateItemType createItemRequest = new com.webmail.CreateItemType();
// Set the required SendMeetingInvitations attribute
createItemRequest.SendMeetingInvitations = com.webmail.CalendarItemCreateOrDeleteOperationType.SendToNone;
createItemRequest.SendMeetingInvitationsSpecified = true;
// Add the destination folder to the request.
createItemRequest.SavedItemFolderId = new com.webmail.TargetFolderIdType();
createItemRequest.SavedItemFolderId.Item = folder;
// Add the items to the CreateItem request.
createItemRequest.Items = arrayOfItems;
// Return value containg changeKey and hash Id to identify our appointment(needed for deleteing etc.)
string[] changeKeyHashId = new string[2];
try
{
// Send the request - esb is a ExchangeServiceBinding object instance created in the Part 1 of this tutorial
com.webmail.CreateItemResponseType createItemResponse = binding.CreateItem(createItemRequest);
if (createItemResponse.ResponseMessages.Items == null || createItemResponse.ResponseMessages.Items.Length == 0)
{
return new string[] { "ERROR" };
}
else
{
// Get the response message.
com.webmail.ResponseMessageType[] rmt = createItemResponse.ResponseMessages.Items;
if (rmt[0].ResponseClass != com.webmail.ResponseClassType.Success)
return new string[]
{ "ERROR: " + rmt[0].MessageText
};
else
{
foreach (com.webmail.ResponseMessageType rmtItem in rmt)
{
com.webmail.ArrayOfRealItemsType itemArray = (rmtItem as com.webmail.ItemInfoResponseMessageType).Items;
com.webmail.ItemType[] items = itemArray.Items;
// Get the return values
changeKeyHashId[0] = items[0].ItemId.ChangeKey;
changeKeyHashId[1] = items[0].ItemId.Id;
}
}
}
}
catch (Exception ex)
{
return new string[]
{ "ERROR: " + ex.Message };
} return changeKeyHashId;
}
但是，我一直无法找到任何代码来成功从任何日历中提取任何约会，包括我自己的约会。我的代码的（当前）迭代在com.webmail.GetItemResponseType resp = binding.GetItem（getItemType）中返回“Id is malformed”错误。返回ResponseMessages.Items.MessageText值。这会导致返回的Items为null值。 我的代码如下：
public static void GetCalendarItem()
{
// Set up the binding with credentials and URL.
com.webmail.ExchangeServiceBinding binding = new com.webmail.ExchangeServiceBinding();
binding.Credentials = new System.Net.NetworkCredential("steve.kershaw", "mypasswordhere", "domain.com");
binding.Url = @"https://webmail.com/ews/exchange.asmx";
// Get the Itemtype...
com.webmail.GetItemType getItemType = new com.webmail.GetItemType();
////getItemType.
//com.webmail.GetItemResponseType getItemResponseType = binding.GetItem(getItemType);
// Create the response shape.
com.webmail.ItemResponseShapeType responseShape = new com.webmail.ItemResponseShapeType();
responseShape.BodyType = com.webmail.BodyTypeResponseType.Text;
responseShape.BodyTypeSpecified = true;
responseShape.BaseShape = com.webmail.DefaultShapeNamesType.Default;
// Add more properties to the request.
com.webmail.PathToUnindexedFieldType[] sensitivity = new com.webmail.PathToUnindexedFieldType[1];
sensitivity[0] = new com.webmail.PathToUnindexedFieldType();
sensitivity[0].FieldURI = com.webmail.UnindexedFieldURIType.itemSensitivity;
responseShape.AdditionalProperties = sensitivity;
// Add the response shape to the request.
getItemType.ItemShape = responseShape;
// Identify the items to get.
com.webmail.ItemIdType[] items = new com.webmail.ItemIdType[2];
items[0] = new com.webmail.ItemIdType();
items[0].Id = "AAAlAE1BQG1";
items[0].ChangeKey = "DwAAABYAAAA";
items[1] = new com.webmail.ItemIdType();
items[1].Id = "AAAlAE1BQG1";
items[1].ChangeKey = "DwAAABYAAAA";
// Add items to the request.
getItemType.ItemIds = items;
try
{
// Send the request and get the response.
com.webmail.GetItemResponseType resp = binding.GetItem(getItemType);
com.webmail.ArrayOfResponseMessagesType aormt = resp.ResponseMessages;
com.webmail.ResponseMessageType[] rmta = aormt.Items;
foreach (com.webmail.ResponseMessageType rmt in rmta)
{
com.webmail.ItemInfoResponseMessageType iirmt = (rmt as com.webmail.ItemInfoResponseMessageType);
com.webmail.ArrayOfRealItemsType aorit = iirmt.Items;
com.webmail.ItemType[] myItems = aorit.Items;
// Determine the type for each item and cast to the approriate type.
foreach (com.webmail.ItemType it in myItems)
{
// Check whether it is an e-mail.
if (it is com.webmail.MessageType)
{
com.webmail.MessageType message = (it as com.webmail.MessageType);
}
// Determine whether it is a calendar item.
else if (it is com.webmail.CalendarItemType)
{
com.webmail.CalendarItemType calendar = (it as com.webmail.CalendarItemType);
}
else
{
// Check for other item types.
}
}
}
}
catch (Exception e)
{
throw new Exception("GetItem failed");
}
}
是否可以轻松地将日历中的所有约会拉到特定日期范围内？！
答案 0 :(得分：1)
请注意，FindItem还会返回所有重复事件，您可能希望从那些事件中获取主事件。 请参阅我在Delete recurring calendar item with PHP EWS?
的回答我不能给你任何C代码，我在Delphi中通过我自己的'SOAP'调用它。
