+# IResourceLoader::Load
+
+```cpp
+LoadResult Load(const Containers::String& path, const ImportSettings* settings = nullptr)
+```
+
+同步加载资源。纯虚方法，由具体加载器实现。从指定路径读取文件数据，解析为对应类型的资源对象。
+
+**参数：**
+- `path` - 资源文件路径
+- `settings` - 可选的导入设置，用于自定义加载行为
+
+**返回：** `LoadResult`，包含加载结果（资源指针、是否成功、错误信息等）
+
+**复杂度：** O(n)，取决于文件大小
+
+**示例：**
+
+```cpp
+LoadResult TextureLoader::Load(const Containers::String& path,
+                               const ImportSettings* settings) {
+    LoadResult result;
+    auto data = ReadFileData(path);
+    if (data.Empty()) {
+        result.errorMessage = "Failed to read file: " + path;
+        return result;
+    }
+    Texture* tex = new Texture();
+    if (!tex->LoadFromData(data.Data(), data.Size(), settings)) {
+        delete tex;
+        result.errorMessage = "Failed to parse texture data";
+        return result;
+    }
+    result.resource = tex;
+    result.success = true;
+    return result;
+}
+```
