如何从文件夹和PublicFolders的子文件夹的所有项目使用EWS托管API(How To Ge

如何从“公共文件夹”和“子文件夹”的所有项目，以换取server2010 uisng管理器API

rootfolder = Folder.Bind(service,WellKnownFolderName.PublicFoldersRoot);
rootfolder.Load();                                             
foreach (Folder folder in rootfolder.FindFolders(new FolderView(int.MaxValue)))
{
FindItemsResults<Item> findResults = folder.FindItems(iv); 
 foreach (Item item in findResults)

         {
            //get item info;
         } 
}

“如果我不喜欢这个我没有得到项目目前在it..public文件夹的子文件夹不支持深度遍历查询too..How我可以得到公共文件夹的子文件夹的项目???”

Answer 1:

要获得所有文件夹，使用下面的代码：

public void GetAllFolders(ExchangeService service, List<Folder> completeListOfFolderIds)
    {
        FolderView folderView = new FolderView(int.MaxValue);
        FindFoldersResults findFolderResults = service.FindFolders(WellKnownFolderName.PublicFoldersRoot, folderView);
        foreach (Folder folder in findFolderResults)
        {
            completeListOfFolderIds.Add(folder);
            FindAllSubFolders(service, folder.Id, completeListOfFolderIds);
        }
    }

private void FindAllSubFolders(ExchangeService service, FolderId parentFolderId, List<Folder> completeListOfFolderIds)
    {
        //search for sub folders
        FolderView folderView = new FolderView(int.MaxValue);
        FindFoldersResults foundFolders = service.FindFolders(parentFolderId, folderView);

        // Add the list to the growing complete list
        completeListOfFolderIds.AddRange(foundFolders);

        // Now recurse
        foreach (Folder folder in foundFolders)
        {
            FindAllSubFolders(service, folder.Id, completeListOfFolderIds);
        }
    }

要获得所有项目：

List<Folder> completeListOfFolderIds = new List<Folder>();
//Fills list with all public folders and subfolders
GetAllFolders(service, completeListOfFolderIds);
foreach(Folder folder in completeListOfFolderIds)
{
ItemView itemView = new ItemView(int.MaxValue);
FindItemsResults<Item> searchResults = service.FindItems(folder.Id, itemView);
//do something with item list    
}

Answer 2:

您需要执行公用文件夹树的递归遍历。 你不能在公共文件夹进行深度遍历。

Answer 3:

public IEnumerable<Item> FindItemsInSubfolders(FolderId root, SearchFilter itemsFilter)
{
    foreach (Folder folder in service.FindFolders(root, new FolderView(int.MaxValue) { Traversal = FolderTraversal.Deep }))
        foreach(Item item in service.FindItems(folder.Id, itemsFilter, new ItemView(int.MaxValue)))
            yield return item;

    foreach (Item item in service.FindItems(root, itemsFilter, new ItemView(int.MaxValue)))
        yield return item;
}
