c# - 如何指定在哪个文件夹中创建新的 Outlook AppointmentItems？

Question

我正在使用以下代码为 outlook 创建 AppointmentItem 对象:

AppointmentItem apt = (APPointmentItem)OLApp.CreateItem(OlItemType.olAppointmentItem);
// set parameters for 'apt', like body, subject etc.
// ...
apt.Save();

我有一个日历的名称，我想将此事件放入其中，但我不知道如何指定新创建的事件应放入哪个文件夹。新事件似乎总是出现在主日历文件夹中。

找到解决方案。感谢 Eugene Astafiev 在 http://www.add-in-express.com/creating-addins-blog/2011/11/04/outlook-create-appointment-item/ 提供它

所以上面的代码应该是:

    using Microsoft.Office.Interop.Outlook;

    Application outlookApplication = new Application();
    MAPIFolder customer_folder = GetMyFolder(path, outlookApplication.Session.Folders);  //function to get your folder
    AppointmentItem apt = (AppointmentItem)customer_folder.Items.Add(OlItemType.olAppointmentItem);
    // set parameters for 'apt', like body, subject etc.
    // ...
    apt.Save();

下面是 GetMyFolder 递归查找自定义文件夹的代码:

    using System.Collections;
    using System.Linq;
    using Microsoft.Office.Interop.Outlook;

    private MAPIFolder _mapiFolder;

    private MAPIFolder GetMyFolder(string path, IEnumerable folders)
    {
        if (!path.StartsWith(@"\\", StringComparison.Ordinal))
            return null;

        string pathRoot = GetFolderPathRoot(path);

        foreach (Folder folder in folders.Cast<Folder>().TakeWhile(
            folder => _mapiFolder == null).Select(
                folder => new { folder, folderRoot = GetFolderPathRoot(folder.FolderPath) }).Where(
                    folder => folder.folderRoot == pathRoot).Select(folder => folder.folder))
        {
            if (folder.DefaultItemType == OlItemType.olAppointmentItem && folder.FolderPath == path)
            {
                s_mapiFolder = folder;
                break;
            }

            if (folder.Folders.Cast<Folder>().Any())
                GetMapiFolder(false, folder.Folders, path);
        }

        return _mapiFolder;
    }

    private static string GetFolderPathRoot(string folderPath)
    {
        // Strip header directory seperator characters
        folderPath = folderPath.Remove(0, 2);

        // Find the index of a directory seperator character
        int index = folderPath.IndexOf(Path.DirectorySeparatorChar, 0);

        // Reconstruct the root path according to the index found
        return String.Format(@"\\{0}", index > 0 ? folderPath.Substring(0, index) : folderPath);
    }

编辑:修改代码以仅在指定路径根目录下的文件夹中递归搜索。
