如何通过C#在Outlook自动化中指向正确的存储区？

using Outlook = Microsoft.Office.Interop.Outlook;

Outlook.Application outlookApp = new Outlook.Application();

Outlook.NameSpace outlookNamespace = outlookApp.GetNamespace("MAPI");
Outlook.Folders rootFolders = outlookNamespace.Folders;

string targetStorageName = "Target Storage Name";
Outlook.MAPIFolder targetStorage = null;

foreach (Outlook.Folder folder in rootFolders)
{
    if (folder.Name == targetStorageName)
    {
        targetStorage = folder;
        break;
    }
}

Outlook.Folders subFolders = targetStorage.Folders;
