将实体添加到Autocad命令选择集

Question

我想要做的事情与下面的代码类似。而不是从选择集中删除实体，我想添加包含某些xdata的实体。这是可能的还是我要求月亮？以下链接适用于此处显示的代码。

SelectionAddedEventHandler

public class MyCommands 
{ 
[CommandMethod("MyReactor")] 
public void MyReactor() 
{ 
    Editor ed = acApp.DocumentManager.MdiActiveDocument.Editor; 
    ed.SelectionAdded += new SelectionAddedEventHandler(ed_SelectionAdded); 
} 

void ed_SelectionAdded(object sender, SelectionAddedEventArgs e) 
{ 
    string cmds = (string)acApp.GetSystemVariable("CMDNAMES"); 
    if (!cmds.StartsWith("COPY")) 
     return; 
    int i = 0; 
    List<int> indices = new List<int>(); 
    foreach (SelectedObject selObj in e.AddedObjects) 
    { 
     if (selObj.ObjectId.ObjectClass == RXClass.GetClass(typeof(Circle))) 
      indices.Insert(0, i); 
     i++; 
    } 
    foreach (int current in indices) 
     e.Remove(current); 
} 
}

你有没有尝试过这样的事情吗？

ObjectId acObjId = //the object id of the xdata object 
SelectedObject obj = new SelectedObject(acObjId, null); 
e.Add(obj);
