HttpListner.Start()でアクセス拒否された話

Posted at

現象

下記のようなコードを書いたところ、HttpListenerException が発生した。

// string endPoint = "http://localhost:8080"; // こちらは例外でない
string endPoint = "http://<host>:8080"; // こっちは例外が出る
HttpListener server = new HttpListener();
server.Prefixes.Add(endPoint);
server.Start();

対策

ネットで調べたところ、管理者で実行しないとエラーになるらしい
参考) http://sweep3092.hatenablog.com/entry/2014/12/27/160005

参考元の記述に従い、マニフェストファイルでプログラムを管理者権限で実行するよう、修正した。

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
