答案 0 :(得分：2)
答案 1 :(得分：1)
使用System.Windows.Forms命名空间。要使用System.Windows.Forms命名空间，您必须添加System.Windows.Forms.dll作为参考。
要添加参考，请按照以下步骤操作：
在Solution Explorer中，右键单击项目节点，然后单击Add Reference。
在Add Reference对话框中，选择.NET选项卡并选择System.Windows.Forms并单击OK。
答案 2 :(得分：1)
ListBox和PictureBox控件都可以在System.Windows.Forms命名空间中找到。将以下语句添加到代码顶部：
使用System.Windows.Forms;
然后添加对System.Windows.Forms.dll
