public EwsItemList DownloadItems(
	FolderId id,
	bool unreadOnly
)

Public Function DownloadItems ( 
	id As FolderId,
	unreadOnly As Boolean
) As EwsItemList

Parameters

id

Type: FolderId
The ID of the folder. Null reference (Nothing in Visual Basic) not allowed.

unreadOnly

Type: SystemBoolean
If true, only unread items are downloaded; otherwise, all the items.

Return Value

To specify the folder by its name, first get its ID with FindFolderIdByShortName(FolderId, String) or FindFolderIdByFullName(String) method.

This method can be slow or even time out for folders with thousands of items. For large folders, it's recommended to use overloads which let you specify item ranges.

Note
This overload downloads only basic properties of Exchange items. You need to use other overloads to get full e-mail messages.

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