发几个.Net标注相关的方法
只有代码，没有演示，就这么干看着不合适，不适合，来上传个演示看看，演示中所有标准均为这几个标注方法创建！！！///
/// 将图形添加到图形文件中---本方法为李小科.Net封装方法

/// 图形数据库
/// 图形对象
/// ObjectId图元名

ObjectId entId = ObjectId.Null;
//开启事务处理
using (Transaction trans = db.TransactionManager.StartTransaction())

BlockTable bt = (BlockTable)trans.GetObject(db.BlockTableId, OpenMode.ForRead);
//打开块表记录
BlockTableRecord btr = (BlockTableRecord)trans.GetObject(bt, OpenMode.ForWrite);
//添加图形到块表记录
entId = btr.AppendEntity(ent);
//更新数据信息
trans.AddNewlyCreatedDBObject(ent, true);
//提交事务
trans.Commit();
}
