+
+```cpp
+bool Contains(const Key& key) const;
+```
+
+检查哈希表中是否包含指定的键。
+
+**参数：**
+- `key` - 要检查的键
+
+**返回：** 如果键存在返回 `true`，否则返回 `false`。
+
+**复杂度：** O(1) 平均，最坏 O(n)
+
+**示例：**
+
+```cpp
+XCEngine::Containers::HashMap<int, const char*> map;
+map.Insert(1, "one");
+map.Insert(2, "two");
+
+if (map.Contains(1)) {
+    std::cout << "Key 1 exists" << std::endl; // 输出 "Key 1 exists"
+}
+
+if (!map.Contains(99)) {
+    std::cout << "Key 99 does not exist" << std::endl; // 输出 "Key 99 does not exist"
+}
+```
