c# OutlookBar控件

最近在上网的时候，发现了这个C# 下的 OutlookBar 控件，看了一下感觉还真不错，特此记录一下。

using System;
using System.Drawing;
using System.Windows.Forms;namespace OutLookBarDemo

}OutlookBar 组件代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;namespace OutLookBarDemo

}调用代码

虽然调用和获取这块有点费劲，但是还是不错的一款组件。
