c# - 如何为 Outlook AppointmentItem 的类别着色

Question

我正在使用 office .NET 框架在 Outlook 中创建约会。创建约会的代码如下所示:

    private void createCalendarEvent(DateTime start, DateTime end, String dept, String subj, String subjType, String room)
    {
        AppointmentItem apt = (AppointmentItem)OLapp.CreateItem(OlItemType.olAppointmentItem);

        apt.Start = start;
        apt.End = end;
        apt.Subject = subj + " - " + subjType;
        apt.Body = "Subject: " + subj + " (" + subjType + ")"
                + "\nDepartment: " + dept
                + "\nRoom: " + room
                + "\n\nCreated by " + this.Text
                + "\n On " + DateTime.Now.ToLongDateString() + " At " + DateTime.Now.ToLongTimeString();
        apt.Location = room;
        apt.Categories = subj;
        apt.Save();
    }

这工作得很好，但我设置的类别没有与之关联的颜色。我希望 outlook 中的约会根据类别集以不同的颜色显示。有什么方法可以手动设置类别颜色吗？或者更好的是，让框架自动为我选择类别颜色的方法？

this question 的答案处理类别。具体来说，这里有一些代码(VB.net，但很容易转换)将创建一个深橄榄色类别:

Private Shared ReadOnly CATEGORY_TEST As String = "Custom Overdue Activity"

' This method checks if our custom category exists, and creates it if it doesn't.
Private Sub SetupCategories()
    Dim categoryList As Categories = Application.Session.Categories
    For i As Integer = 1 To categoryList.Count
        Dim c As Category = categoryList(i)
        If c.Name.Equals(CATEGORY_TEST) Then
            Return
        End If
    Next

    categoryList.Add(CATEGORY_TEST, Outlook.OlCategoryColor.olCategoryColorDarkOlive)
End Sub

类别颜色要么在 Outlook 中设置，要么在代码中创建类别时在上面的代码中设置。
