您的对话框中存在问题

public class MenuItem
{
     public int Id { get; set; }
     public bool Divider { get; set; }
     public bool Header { get; set; }
     public string ActionName { get; set; }
     public string ControllerName { get; set; }
     public string MenuItemText { get; set; }
     public string Title { get; set; }
     public IList<string> Roles { get; set; }
     public int ParentId { get; set; }
}
var MenuList = new List<MenuItem>();
var menuItem = new MenuItem
{
    Id = 1,
    Divider = true,
    Header = true,
    ActionName = "Scheduling",
    ControllerName = "Index",
    MenuItemText = "sdfs",
    Title = "Scheduling",
    Roles = new List<string>{"rol1", "rol2"},
    ParentId = 30
};
MenuList.Add(menuItem);
