ResXResourceReader.BasePath 屬性
定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得或設定 ResXFileRef 物件中指定之相對檔案路徑的基底路徑。
public:
property System::String ^ BasePath { System::String ^ get(); void set(System::String ^ value); };public string BasePath { get; set; }public string? BasePath { get; set; }member this.BasePath : string with get, setPublic Property BasePath As String屬性值
路徑，如果在 ResXFileRef 物件中指定的相對檔案路徑之前加上該路徑，則該路徑會產生資源檔的絕對路徑。
例外狀況
在設定作業中無法指定值，因為已經存取 XML 資源檔，而且正在使用中。
範例
下列範例會建立 XML 資源檔，其中包含狗狗的影像，也會建立字串資源，指定建立資源的應用程式。 ResXFileRef 物件是用來儲存影像的路徑，而不是將二進位影像本身儲存在資源檔中。 此範例會 BasePath 設定 屬性，讓影像檔案名中的相對檔案路徑解譯為名為 C：\data\ 之目錄的子目錄。

請注意，您必須將參考新增至 System.Drawing.dll，才能順利編譯專案。 此範例也需要必要的映射存在於名為 C：\data\images\ 的目錄中。
備註
屬性 BasePath 是用來解析指派給 FileName 物件屬性的 ResXFileRef 相對檔案路徑參考。 根據預設，其值為 String.Empty ，而且相對檔案路徑參考會與 屬性所 Environment.CurrentDirectory 傳回的目前目錄關聯性來解析。 您應該先設定此屬性，再開始列舉資源。
