摘要：TOCControl图层跟树状列表，代码如下 private bool bandingTree(ILayer rootLayer, TreeNode Node, string strRoot) { ICompositeLayer cmpLayer = rootLayer as ICompositeLayer; if (cmpLayer != null) { for (int i = 0; i < cmpLayer.Count; i++) { ILayer nextCmpLayer = cmpLayer.get_Layer(i); TreeNode childNode = new Tree 阅读全文

摘要：通过IMap中的get_layers()可以遍历MapControl中当前的图层。此方法可以通过指定UID对图层进行过滤或者分类。1. 遍历矢量图层public IEnumLayer GetFeatureLayers(){UID uid = new UIDClass();uid.Value = "{40A9E885-5533-11d0-98BE-00805F7CED21}";//FeatureLayerIEnumLayer layers = frmMap.m_mapCtrl.Map.get_Layers(uid, true);return layers;}2. 遍历栅格图层 阅读全文
