此示例创建一个 Pen 对象。
示例：
System::Drawing::Pen^ myPen;
myPen = gcnew System::Drawing::Pen(System::Drawing::Color::Tomato);
System.Drawing.Pen myPen;
myPen = new System.Drawing.Pen(System.Drawing.Color.Tomato);
Dim myPen As System.Drawing.Pen
myPen = New System.Drawing.Pen(System.Drawing.Color.Tomato)
可靠的编程
使用消耗系统资源的对象（例如Pen 对象）后，应调用Dispose。
