如何初始化內聯的ControlCollection控制的控制

Question

這真讓我心煩，我不能做到這一點

Panel panel = new Panel() 
    { 
     Controls = new ControlCollection(this) 
     { 
      new Panel() 
      { 
       Controls = new ControlCollection(this) 
       { 
        new Label() { Text = "Label1" }, 
        new Label() { Text = "Label2" } 
       } 
      } 
     } 
    }; 

因爲，在這種特殊情況下，我得到Property or indexer 'Control.Controls' cannot be assigned to -- it is read only的財產。

，而是我必須這樣做

Panel innerPanel = new Panel(); 
    innerPanel.Controls.Add(new Label() { Text = "Label1" }); 
    innerPanel.Controls.Add(new Label() { Text = "Label2" }); 
    Panel panel = new Panel(); 
    panel.Controls.Add(innerPanel); 

任何聰明的方式來獲取樹一樣的代碼風格與我們合作？

簡單地忽略ControlCollection構造函數調用：

Panel panel = new Panel 
{ 
    Controls = 
    { 
     new Panel 
     { 
      Controls = 
      { 
       new Label { Text = "Label1" }, 
       new Label { Text = "Label2" } 
      } 
     } 
    } 
}; 

這將Panel和Label子控件添加的，而不是創建新的對象ControlCollection由Controls屬性返回的現有ControlCollection對象。
