private async Task BuildGraphWithActiveView()
{await QueuedTask.Run(() =>{//构建地图拓扑图MapView.Active.BuildMapTopologyGraph<TopologyDefinition>(async topologyGraph =>{//获取图中的节点和边var topologyGraphNodes = topologyGraph.GetNodes();var topologyGraphEdges = topologyGraph.GetEdges();foreach (var node in topologyGraphNodes){// 对节点进行处理}foreach (var edge in topologyGraphEdges){// 对边进行处理}MessageBox.Show($"拓扑图中的节点数量为: {topologyGraphNodes.Count}。\n 拓扑图中的边数量为 {topologyGraphEdges.Count}。", "地图拓扑信息");});});
}
