所有文件夹中的Exchange Web服务（EWS）FindItems [英] Exchange Web Services (EWS) FindItems within All Folders

问题描述

我使用下面的代码来找到所有来自用户发送这些电子邮件，然而，这仅搜索主收件箱文件夹和不检查任何子文件夹。我想搜索所有邮件项目包括所有子文件夹。

我曾尝试WellKnownFolderName.Root和WellKnownFolderName.Inbox而这些只能搜索这些文件夹，而不是子文件夹。

 私有静态无效SearchItems（字符串email）
 {
 ItemView控件IV =新ItemView控件（10）; 
 FindItemsResults<项目> fiitems = _service.FindItems（WellKnownFolderName.Inbox，来自：[e-mail]，IV）; 
 
的foreach（在fiitems项项）
 {
 Console.WriteLine（主题：\t+ item.Subject）; 
 Console.WriteLine（接受过：\t\t+ item.DateTimeReceived.ToString（DD MMMM YYYY））; 
 Console.WriteLine（）; 
} 
 
 Console.WriteLine（按Enter键继续）; 
到Console.ReadLine（）; 
} 
  

解决方案

我已经发现了一些信息，在格伦的博客 http://gsexdev.blogspot.com /2011/08/using-allitems-search-folder-from.html 我已经移植了PowerShell脚本到C＃，如下图所示。

 私有静态无效SearchItems（）
 {
 
 ExtendedPropertyDefinition allFoldersType =新ExtendedPropertyDefinition（13825，MapiPropertyType.Integer）; 
 
 FolderId rootFolderId =新FolderId（WellKnownFolderName.Root）; 
文件夹视图文件夹视图=新的文件夹视图（1000）; 
 folderView.Traversal = FolderTraversal.Shallow; 
 
 SearchFilter searchFilter1 =新SearchFilter.IsEqualTo（allFoldersType，2）; 
 SearchFilter searchFilter2 =新SearchFilter.IsEqualTo（FolderSchema.DisplayNameallitems）; 
 SearchFilter.SearchFilterCollection searchFilterCollection =新SearchFilter.SearchFilterCollection（LogicalOperator.And）; 
 searchFilterCollection.Add（searchFilter1）; 
 searchFilterCollection.Add（searchFilter2）; 
 
 FindFoldersResults findFoldersResults = _service.FindFolders（rootFolderId，searchFilterCollection，文件夹视图）; 
 
如果（findFoldersResults.Folders.Count大于0）
 {
夹allItemsFolder = findFoldersResults.Folders [0]; 
 Console.WriteLine（文件夹：\t+ allItemsFolder.DisplayName）; 
 
 ItemView控件IV =新ItemView控件（1000）; 
 FindItemsResults<项目> findResults = allItemsFolder.FindItems（System.Message.DateReceived：01/01 / 2011..01 / 31/2011」，IV）; 
 
的foreach（在findResults项项）
 {
 Console.WriteLine（主题：\t+ item.Subject）; 
 Console.WriteLine（接受过：\t\t+ item.DateTimeReceived.ToString（DD MMMM YYYY））; 
 Console.WriteLine（是新的：\t\t+ item.IsNew.ToString（））; 
 Console.WriteLine（有附件：\t\t+ item.HasAttachments.ToString（））; 
 Console.WriteLine（）; 
} 
 
} 
 
 Console.WriteLine（按Enter键继续）; 
到Console.ReadLine（）; 
} 
  

I am using the following code to find all the emails sent from a user, however this only searches the main Inbox folder and doesn't check any sub-folders. I would like to search all the mail items including any sub-folders.

I have tried the WellKnownFolderName.Root and WellKnownFolderName.Inbox and these only search those folders, not the sub-folders.

    private static void SearchItems(string email)
    {
        ItemView iv = new ItemView(10);
        FindItemsResults<Item> fiitems = _service.FindItems(WellKnownFolderName.Inbox, "from:[e-mail]", iv);

        foreach (Item item in fiitems)
        {
            Console.WriteLine("Subject:\t" + item.Subject);
            Console.WriteLine("Received At:\t\t" + item.DateTimeReceived.ToString("dd MMMM yyyy"));
            Console.WriteLine();
        }

        Console.WriteLine("Press Enter to continue");
        Console.ReadLine();
    }

解决方案

I have found some information on the AllItems folder within Exchange over at Glen's blog http://gsexdev.blogspot.com/2011/08/using-allitems-search-folder-from.html I have ported the PowerShell script to C# as shown below.

    private static void SearchItems()
    {

        ExtendedPropertyDefinition allFoldersType = new ExtendedPropertyDefinition(13825, MapiPropertyType.Integer);

        FolderId rootFolderId = new FolderId(WellKnownFolderName.Root);
        FolderView folderView = new FolderView(1000);
        folderView.Traversal = FolderTraversal.Shallow;

        SearchFilter searchFilter1 = new SearchFilter.IsEqualTo(allFoldersType, "2");
        SearchFilter searchFilter2 = new SearchFilter.IsEqualTo(FolderSchema.DisplayName, "allitems");
        SearchFilter.SearchFilterCollection searchFilterCollection = new SearchFilter.SearchFilterCollection(LogicalOperator.And);
        searchFilterCollection.Add(searchFilter1);
        searchFilterCollection.Add(searchFilter2);

        FindFoldersResults findFoldersResults = _service.FindFolders(rootFolderId, searchFilterCollection, folderView);

        if (findFoldersResults.Folders.Count > 0)
        {
            Folder allItemsFolder = findFoldersResults.Folders[0];
            Console.WriteLine("Folder:\t" + allItemsFolder.DisplayName);

            ItemView iv = new ItemView(1000);
            FindItemsResults<Item> findResults = allItemsFolder.FindItems("System.Message.DateReceived:01/01/2011..01/31/2011", iv);

            foreach (Item item in findResults)
            {
                Console.WriteLine("Subject:\t" + item.Subject);
                Console.WriteLine("Received At:\t\t" + item.DateTimeReceived.ToString("dd MMMM yyyy"));
                Console.WriteLine("Is New:\t\t" + item.IsNew.ToString());
                Console.WriteLine("Has Attachments:\t\t" + item.HasAttachments.ToString());
                Console.WriteLine();
            }

        }

        Console.WriteLine("Press Enter to continue");
        Console.ReadLine();
    }
