範例 XML 檔案：客戶和訂單 (LINQ to XML)

  • 發行項

下列 XML 檔案用於 LINQ to XML 文件的各種範例中。 這個檔案包含客戶和訂單。

範例 XSD 檔案：客戶和訂單一文包含可用於驗證此文件的 XSD。 它會使用 XSD 的 xs:key 和 xs:keyref 功能來建立 CustomerID 項目的 Customer 屬性為索引鍵，並在每個 CustomerID 項目中的 Order 項目和每個 CustomerID 項目中的 Customer 屬性之間建立關聯性。

如需撰寫透過 Join 子句利用此關聯性之 LINQ 查詢的範例，請參閱如何聯結兩個集合。
