public EwsFolder GetFolderByName(
	string folderFullName,
	List<EwsFolder> folders
)

Public Function GetFolderByName ( 
	folderFullName As String,
	folders As List(Of EwsFolder)
) As EwsFolder

Parameters

folderFullName

Type: SystemString
The full folder name.

folders

Type: System.Collections.GenericListEwsFolder
The list of folders to search.

Return Value

This method does not send anything to the MS Exchange server, neiter it does any I/O at all (therefore it doesn't have an async version). It just performs search over the provided collection. To get the list of folders which you can then supply to this method, you can use DownloadFolders(Boolean) method.

To delimit levels of hierarchy in the folder name, use the same character which is set by FolderLevelDelimiter property. By default, it's '/' (forward slash).

Note
Although you could always call a method like DownloadFolderByFullName(String) to find folders, it may not be effective if you need to make multiple folder search queries. If (instead of making a network query each time) you download folders only once and then access the cached list with GetFolderByName(String, ListEwsFolder) method, you'll achieve better performance.
