public EwsItemList DownloadItems(
	IEnumerable<EwsItem> itemIds,
	PropertySet properties
)

Public Function DownloadItems ( 
	itemIds As IEnumerable(Of EwsItem),
	properties As PropertySet
) As EwsItemList

Parameters

itemIds

Type: System.Collections.GenericIEnumerableEwsItem
The IDs of the items to download. Null reference (Nothing in Visual Basic) not allowed

properties

Type: PropertySet
The settings which specify which portions of MS Exchange items to download (e.g. item ID, mail header, body, etc). If a null reference, only item ID is requested.

Return Value

To get the list of item IDs for downloading you can use DownloadItemIds(FolderId, Boolean) or Search(FolderId, SearchFilter) methods.

You can build PropertySet object manually or use CreatePropSet(EwsItemParts) method for this (or just use DownloadItems(IEnumerable<EwsItem>, EwsItemParts) overload).

Note
This method is not implemented in .NET Core. Use DownloadItemsAsync(IEnumerableEwsItem, PropertySet) instead.
