如何将新列添加到包含任务类型元素的文件夹中？如何将任务添加到特定文件夹？

Question

如何将新列添加到包含任务类型元素的文件夹中（我想添加列“ project”，“ ID”）？如何将任务添加到特定文件夹，例如，添加到文件夹“ MyRedmineTasks”？ 请帮忙。

我试图将任务添加到特定文件夹中，并在该文件夹中添加列。

Outlook.MAPIFolder inBox = (Outlook.MAPIFolder)  
this.Application.ActiveExplorer().Session.GetDefaultFolder
            (Outlook.OlDefaultFolders.olFolderTasks);
string userName = "Для Redmine16";

Outlook.MAPIFolder customFolder = null;
try
{
//add folder
    customFolder = (Outlook.MAPIFolder)inBox.Folders.Add(userName,
                Outlook.OlDefaultFolders.olFolderTasks);
//create a task item.Outlook.TaskItem newTaskItem =      
(Outlook.TaskItem)Globals.ThisAddIn.
Application.CreateItem(Outlook.OlItemType.olTaskItem);
newTaskItem.StartDate = DateTime.Now.AddHours(2);

newTaskItem.Body = "MyTask";
newTaskItem.Save();

MessageBox.Show("You have created a new folder named " +userName + ".");
inBox.Folders[userName].Display();

//Create table in task folder
Outlook.TableView CurView =((Outlook.TableView)customFolder.CurrentView);

// remove columns

while (CurView.ViewFields.Count > 1)
{

 CurView.ViewFields.Remove(1);

}

// re-add good columns
CurView.ViewFields.Add("Id");

CurView.ViewFields.Add("Priority");

CurView.ViewFields.Add("Status");
}
catch (Exception ex)
{
    MessageBox.Show("The following error occurred: " + ex.Message);
}



//this code doesn't work
//Error: The field does not exist in this folder.
