DataServiceQuery<TElement>.IncludeTotalCount 메서드

정의

엔터티 집합의 모든 엔터티 수가 쿼리 결과와 함께 인라인으로 반환되도록 요청합니다.

public:
 System::Data::Services::Client::DataServiceQuery<TElement> ^ IncludeTotalCount();
public System.Data.Services.Client.DataServiceQuery<TElement> IncludeTotalCount ();
member this.IncludeTotalCount : unit -> System.Data.Services.Client.DataServiceQuery<'Element>
Public Function IncludeTotalCount () As DataServiceQuery(Of TElement)

반환

inline count 옵션이 설정된 새 DataServiceQuery<TElement> 개체입니다.

예제

이 예제에서는 메서드를 호출한 후 쿼리를 실행합니다 IncludeTotalCount . 속성은 TotalCount 쿼리에서 반환되는 엔터티 수를 확인하는 데 사용됩니다.

// Create the DataServiceContext using the service URI.
NorthwindEntities context = new NorthwindEntities(svcUri);

// Define a new query for Customers that includes the total count.
DataServiceQuery<Customer> query = context.Customers.IncludeTotalCount();

try
{
    // Execute the query for all customers and get the response object.
    QueryOperationResponse<Customer> response =
        query.Execute() as QueryOperationResponse<Customer>;

    // Retrieve the total count from the response.
    Console.WriteLine("There are a total of {0} customers.", response.TotalCount);

    // Enumerate the customers in the response.
    foreach (Customer customer in response)
    {
        Console.WriteLine("\tCustomer Name: {0}", customer.CompanyName);
    }
}
catch (DataServiceQueryException ex)
{
    throw new ApplicationException(
        "An error occurred during query execution.", ex);
}
' Create the DataServiceContext using the service URI.
Dim context = New NorthwindEntities(svcUri)

' Define a new query for Customers that includes the total count.
Dim query As DataServiceQuery(Of Customer) = _
context.Customers.IncludeTotalCount()

Try
    ' Execute the query for all customers and get the response object.
    Dim response As QueryOperationResponse(Of Customer) = _
        CType(query.Execute(), QueryOperationResponse(Of Customer))

    ' Retrieve the total count from the response.
    Console.WriteLine("There are a total of {0} customers.", response.TotalCount)

    ' Enumerate the customers in the response.
    For Each customer As Customer In response
        Console.WriteLine(vbTab & "Customer Name: {0}", customer.CompanyName)
    Next
Catch ex As DataServiceQueryException
    Throw New ApplicationException( _
            "An error occurred during query execution.", ex)
End Try

설명

메서드를 IncludeTotalCount 호출하는 것은 쿼리 URI에 $inlinecount 쿼리 옵션을 포함하는 것과 같습니다.
