Here’s the simple example that creates, renames and deletes an IMAP folder using Mail.dll IMAP library<\/a>:<\/p>\n

\r\n\/\/ C# version:\r\n\r\nusing Limilabs.Mail;\r\nusing Limilabs.Client.IMAP;\r\n\r\nclass Program\r\n{\r\n    static void Main(string[] args)\r\n    {\r\n       using (Imap imap = new Imap())\r\n       {\r\n           imap.Connect("server.company.com");\r\n           imap.Login("user", "password");\r\n\r\n           imap.SelectInbox();\r\n\r\n           imap.CreateFolder("New folder");\r\n           imap.RenameFolder("New folder", "Better name");\r\n           imap.DeleteFolder("Better name");\r\n\r\n           imap.Close();\r\n       }\r\n    }\r\n};\r\n<\/pre>\n
\r\n' VB.NET version:\r\n\r\nImports Limilabs.Mail\r\nImports Limilabs.Client.IMAP\r\n\r\nPublic Module Module1\r\n    Public Sub Main(ByVal args As String())\r\n\r\n        Using imap As New Imap()\r\n            imap.Connect("server.company.com")\r\n            imap.Login("user", "password")\r\n\r\n            imap.SelectInbox()\r\n\r\n            imap.CreateFolder("New folder")\r\n            imap.RenameFolder("New folder", "Better name")\r\n            imap.DeleteFolder("Better name")\r\n\r\n            imap.Close()\r\n        End Using\r\n\r\n    End Sub\r\nEnd Module\r\n\r\n<\/pre>\n
Checking if folder exist<\/h2>\n
The simplest way is to get a list with all folders and check if it contains the name you are looking for. <\/p>\n
\r\nList<FolderInfo> all = imap.GetFolders();\r\nbool exists = all.Find(x => x.Name == "INBOX\/Test folder") != null;\r\n<\/pre>\n
Mail.dll uses FolderInfo<\/em> class to represent IMAP folder. It contains much useful folder information such as Name<\/em>, Flags<\/em>, HasChildren<\/em> and CanSelect<\/em> properties.<\/p>\n
Creating IMAP folder<\/h2>\n
Creating folder is easy and not related to currently selected folder. Folder is always created at root.<\/p>\n
\r\nimap.CreateFolder("Test folder");\r\n<\/pre>\n
To create nested folder, you need to know IMAP server’s separator character. Most common characters are: ‘\/’ (slash) and ‘.’ (dot):<\/p>\n
\r\nimap.CreateFolder("INBOX\/Test folder");\r\n<\/pre>\n
Every FolderInfo<\/em> instance contains SeparatorCharacter<\/em> property:<\/p>\n
\r\nchar separatorCharacter = (char)imap.GetFolders()[0].SeparatorCharacter;\r\n<\/pre>\n
List sub folders<\/h2>\n
Listing direct sub folders<\/strong>:<\/p>\n
\r\nList<FolderInfo> direct = imap.GetFoldersOneLevelDown("INBOX");\r\n<\/pre>\n
Listing all sub folders<\/strong>:<\/p>\n
\r\nList<FolderInfo> all = imap.GetFolders("INBOX");\r\n<\/pre>\n
Get message count<\/h2>\n
If you want to get the number of messages in the folder you can use FolderStatus<\/em> class returned by Imap.Examine<\/em> and Imap.Select<\/em> methods<\/p>\n
\r\nFolderStatus status = imap.Examine("folder");\r\nlong count = status.MessageCount;\r\n<\/pre>\n
To get unseen message count you need to use IMAP search<\/a>, and simply check the Count property of the returned uid list.<\/p>\n
Copying, moving email messages<\/h2>\n
This next sample will shoe how to copy all messages from one folder to another:<\/p>\n
\r\nimap.Select("INBOX\/Source folder");\r\nList<long> uids = imap.GetAll();\r\nimap.CopyByUID(uids, "INBOX\/Destination folder");\r\n<\/pre>\n
You can use Mail.dll .NET IMAP library<\/a> to move messages between folders:<\/p>\n
\r\nimap.Select("INBOX\/Source folder");\r\nList<long> uids = imap.GetAll();\r\nimap.MoveByUID(uids, "Inbox\/Destination folder");\r\n<\/pre>\n
Deleting IMAP folder<\/h2>\n
Deleting IMAP folder is simple, as it does not need to be empty before the operation:<\/p>\n
\r\nimap.DeleteFolder("INBOX\/folder to delete");\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
