最近使用BarManager時候，發現一個問題就是在一開始把BarManager控制元件拖到窗體上的時候，控制元件上會有Add按鈕，如下圖：


此時，新增按鈕或者其餘型別的控制元件，方便無比。但有時候，當你新增完各個BarItem（Bar上的各個小控制元件，比如：BarButtonItem、BarCheckItem等等）後，再過一段時間，突然又有需求，要新增BarItem，發現Add按鈕木有了，那應該怎麼辦呢？

解決方案：

通過程式碼新增。

程式碼修改前：

namespace IconTest
{
    partial class Form1
    {
        /// <summary>
        /// 必需的設計器變數。
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// 清理所有正在使用的資源。
        /// </summary>
        /// <param name="disposing">如果應釋放託管資源，為 true；否則為 false。</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

此時，介面上只有barButtonItemDemo一個控制元件，如圖：


小注：雖然此時Bar上有Add按鈕，但我們仍然通過程式碼新增BarItem。

比如我們仍然要新增一個按鈕BarButtonItem，程式碼如下：

namespace IconTest
{
    partial class Form1
    {
        /// <summary>
        /// 必需的設計器變數。
        /// </summary>

        /// </summary>
        /// <param name="disposing">如果應釋放託管資源，為 true；否則為 false。</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

    }
}

此處新增控制元件為CodeTest，效果如下圖：


此時，就可以進行修改圖片，點選事件之類的處理了，與通過Add按鈕生成的用法一致。

小結：所謂的通過程式碼新增BarItem，即是參照之前的程式碼，手動複製修改一下即可。
