DataServiceQuery<TElement>.IncludeTotalCount Method

Requests that the count of all entities in the entity set be returned inline with the query results.

Namespace:  System.Data.Services.Client
Assembly:  Microsoft.Data.Services.Client (in Microsoft.Data.Services.Client.dll)

public DataServiceQuery<TElement> IncludeTotalCount()

Return Value

Type: System.Data.Services.Client.DataServiceQuery<TElement>
A new DataServiceQuery<TElement> object that has the inline count option set.

Calling the IncludeTotalCount method is equivalent to including the $inlinecount query option in the query URI.

This example executes a query after it calls the IncludeTotalCount method. The TotalCount property is used to determine number of entities returned by the query.

// 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();

    // 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);
