public void Dispose ();

説明

Signals that this UnityWebRequest is no longer being used, and should clean up any resources it is using.

You must call Dispose once you have finished using a UnityWebRequest object, regardless of whether the request succeeded or failed.

安全のため、例外がキャッチされない場合、[UnityWebRequest] が正しくクリーンアップされるように通常、using statement を採用することをお勧めします。
