示例演示将一个 XML 文件与 TreeView 控件绑定，并用 TreeView 控件显示 XML 文件每个 XmlNode 的第一个属性的值。主要的做法是遍历 XML 文件的每个节点，同时在 TreeView 里新建相应的节点，将每个 XML 节点第一个属性的值写入新建的 TreeView 的节点。-Presentation of a sample XML document and bind TreeView controls, and TreeView controls display XML files for each of the first XmlNode attribute value. The main approach is to traverse XML files for each node, at the same time in the new TreeView node corresponding to each XML node attribute value of the first to write a new TreeView nodes.
