+# ResourceDependencyGraph::TopologicalSort
+
+```cpp
+Containers::Array<ResourceGUID> TopologicalSort() const
+```
+
+拓扑排序。按依赖顺序返回所有节点，确保被依赖的资源排在依赖者之前。用于确定正确的加载和卸载顺序。
+
+**参数：** 无
+
+**返回：** 按依赖顺序排序的 GUID 数组
+
+**复杂度：** O(n + e)，n 为节点数，e 为边数
+
+**示例：**
+
+```cpp
+auto loadOrder = graph.TopologicalSort();
+// loadOrder[0] 是最底层依赖（如 Texture）
+// loadOrder[last] 是最顶层资源（如 Material）
+for (const auto& guid : loadOrder) {
+    ResourceManager::Get().Load(guid);
+}
+```
