Paged results

Normally, any FHIR server will limit the number of results returned for the history and search interactions. For these interactions you can also specify the maximum number of results you would want to receive client side.

The FhirClient provides a ContinueAsync method to page through a search or history result Bundle after the first page has been received. ContinueAsync supports a second parameter that specifies the direction in which to page: forward, backward, or directly to the first or last page of the result. The default direction is to retrieve the next page. The method returns null when there is no link for the requested direction in the provided Bundle.

while (result != null)
{
    // Do something with the entries in the result Bundle

    // retrieve the next page of results
    result = await client.ContinueAsync(result);
}

// go to the last page with the direction filled in:
var last_page = await client.ContinueAsync(result, PageDirection.Last);
