C# Treeview树控导航菜单示例，虽然是一个简单的树形菜单实例，不过如果你想实现此类菜单的话，这个例子绝对是很具参考性，因为里面演示了如何创建节点、如何实现分隔符，如何设置图像集合，如何设置不能编辑，如何显示连线，如何显示“+”号和“—”号等，另外还有增加子节点和主节点的方法等，下一步这个示例会结合数据库，实现动态的树形展开菜单。

说明：  梁可视为平面应力状态，先按图示尺寸划分为均匀的三角形网格，共有8×10＝80个单元，5×ll＝55个节点，坐标轴以及单元与节点的编号如图。将均布载荷分配到各相应节点上，把有约束的节点5l、52、53、54、55视作固定铰链，建立如图所示的离散化计算模型。(The beam can be regarded as a plane stress state. Firstly, the beam is divided into uniform triangular meshes according to the graphic size. There are 8*10=80 elements, 5*ll=55 nodes. The coordinate axis and the numbering of elements and nodes are shown in the figure. The uniform load is distributed to the corresponding nodes, and the constrained nodes 5l, 52, 53, 54 and 55 are regarded as fixed hinges. The discrete calculation model shown in the figure is established.)
