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

네임스페이스:  System.Data.Services.Client
어셈블리:  Microsoft.Data.Services.Client(Microsoft.Data.Services.Client.dll)

구문

‘선언
Public Function IncludeTotalCount As DataServiceQuery(Of TElement)
‘사용 방법
Dim instance As DataServiceQuery
Dim returnValue As DataServiceQuery(Of TElement)

returnValue = instance.IncludeTotalCount()

public DataServiceQuery<TElement> IncludeTotalCount()

public:
DataServiceQuery<TElement>^ IncludeTotalCount()

member IncludeTotalCount : unit -> DataServiceQuery<'TElement> 

public function IncludeTotalCount() : DataServiceQuery<TElement>

반환 값

유형: System.Data.Services.Client.DataServiceQuery<TElement>
인라인 카운트 옵션이 설정된 새 DataServiceQuery<TElement> 개체입니다.

주의

IncludeTotalCount 메서드 호출은 쿼리 URI에 $inlinecount 쿼리 옵션을 포함하는 것과 같습니다.

예

이 예제에서는 IncludeTotalCount 메서드를 호출한 후에 쿼리를 실행합니다. TotalCount 속성은 쿼리에서 반환하는 엔터티 수를 결정하는 데 사용됩니다.

' 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

// 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);
}
