範例
下列範例會使用 UrlMappingsSection Web.config 檔案的 來對應兩個 URL，並新增其他 URL 的對應。 當您修改並儲存Web.config檔案時，您的應用程式會重新開機。

備註
類別 UrlMapping 可讓您將顯示的 URL 對應至 Web 應用程式中存在的 URL。 UrlMapping將 物件加入 至 UrlMappingCollection ，相當於在組態檔的 區段中加入 add 元素 urlMappings 的程式設計。
每個 UrlMapping 物件都包含兩個識別 URL 的屬性。 一個屬性會指定向使用者顯示的 URL;另一個 會指定 Web 應用程式中的 URL。 和 MappedUrl 屬性中 Url 會忽略尾端空白字元。
注意
屬性 UrlMapping 可以根據其值為 MachineToApplication 的區段屬性 AllowDefinition 所定義的限制，將資訊寫入組態檔的相關區段。 任何嘗試在階層中不允許的層級寫入組態檔，都會導致剖析器所產生的錯誤訊息。 不過，您可以使用這個類別來讀取階層中任何層級的組態資訊。
