 ### Read an item
 
 In Azure Cosmos DB, you can perform a point read operation by using both the unique identifier (`id`) and partition key fields. In the SDK, call <xref:Microsoft.Azure.Cosmos.Container.ReadItemAsync%2A> passing in both values to return a deserialized instance of your C# type.
 Still in the `GenerateQueryDataAsync` method, use `ReadItemAsync<Product>` to serialize the item using the `Product` type.

 ### Query items
 
 After you insert an item, you can run a query to get all items that match a specific filter. This example runs the SQL query: `SELECT * FROM products p WHERE p.category = "gear-surf-surfboards"`. This example uses the QueryDefinition type and a parameterized query expression for the partition key filter. Once the query is defined, call <xref:Microsoft.Azure.Cosmos.Container.GetItemQueryIterator%2A> to get a result iterator that manages the pages of results. In the example, the query logic is also in the `GenerateQueryDataAsync` method.

 Then, use a combination of `while` and `foreach` loops to retrieve pages of results and then iterate over the individual items.
