C#造实例，对象， 密封类

Question

如下图所示，
var current = ProjectTree.SelectedItem.Tag, debug模式下可以看到 current 的value 是 {Siemens.Engineering.SW.Blocks.PlcBlockSystemGroup}, current的type 是 object {Siemens.Engineering.SW.Blocks.PlcBlockSystemGroup}

现在的问题是，这里的value 和 type指的什么意思。 用花括号代表着什么？ 如果我想新造一个Siemens.Engineering.SW.Blocks.PlcBlockSystemGroup 的对象或者叫实例？ 应该怎么弄？这个类长这样。 我这样写是报错的 PlcSystemBlockGroup current = new PlcSystemBlockGroup();

可以采用父节点的create方法创建节点。再执行导入挂到响应地节点下。有帮助望采纳，谢谢！

        PlcBlockGroup get_relate_group(PlcBlockGroup group, string str_root, string strfile)
        {
            string relate_path = get_relate_path(str_root, strfile);
            string[]dirs = relate_path.Split('\\');
            PlcBlockGroup temp = group;
            for (int i=0;i<dirs.Length-1;i++)
            {
                if(i == 0)
                {
                    if (group.Groups.Find(dirs[i]) == null)
                    {
                        group.Groups.Create(dirs[i]);
                    }
                    temp = group.Groups.Find(dirs[i]);
                }
                else
                {
                    if(temp.Groups.Find(dirs[i]) == null)
                    {
                        temp.Groups.Create(dirs[i]);
                        temp = temp.Groups.Find(dirs[i]);
                    }
                }
            }
