範例

此範例是以 應用程式資源和當地語系化範例的案例 10 為基礎。 請參閱完整解決方案的範例。

備註

版本歷程記錄

Windows 版本	SDK 版本	已新增值
1903	18362	種類

屬性

IsDefault	指出此 ResourceCandidate 是否可以作為任何內容的預設後援值。
IsMatch	指出此 ResourceCandidate 是否符合其評估的 ResourceCoNtext 。
IsMatchAsDefault	指出此 ResourceCandidate 是否比對 ResourceCoNtext ，因為其評估結果為 true 比對、預設後援值，或與預設後援 (的混合比對，也就是與某些限定詞相關的比對，但針對其他限定詞使用預設後援值) 。
Kind	取得封裝在此 ResourceCandidate中的資源類型。
Qualifiers	取得與此 ResourceCandidate相關聯的限定詞。
ValueAsString	取得這個 ResourceCandidate的值，以字串表示。

方法

GetQualifierValue(String)	傳回限定詞的值，指定其名稱。
GetValueAsFileAsync()	以非同步方式傳回 StorageFile ，以存取此 ResourceCandidate的值。 這僅適用于屬於檔案的特定 ResourceCandidate類型。
GetValueAsStreamAsync()	以非同步方式傳回 IRandomAccessStream ，以存取此 ResourceCandidate的值。
