Code Snippet: Implementing a BulkAssociationNavigator
Applies to: SharePoint Server 2010
In this article
Example for a .NET Connectivity Assembly
Example for an ASP.NET Web Service
Example for a WCF Service
The following code examples show how you can implement a BulkAssociationNavigator method instance in a .NET connectivity assembly and in a Web service.
Example for a .NET Connectivity Assembly
public Order[] GetBulkOrdersForCustomers(string[] custids)
{
if (custids == null)
{
return orders.ToArray();
}
else
{
List<Order> ordersForCustomer = new List<Order>();
foreach (Order order in orders)
{
if (Array.Find(
custids, id => id == order.CustomerID) != null)
{
ordersForCustomer.Add(order);
}
}
return ordersForCustomer.ToArray();
}
}
Example for an ASP.NET Web Service
[WebMethod]
public Order[] GetBulkOrdersForCustomers(string[] custids)
{
if (custids == null)
{
return orders.ToArray();
}
else
{
List<Order> ordersForCustomer = new List<Order>();
foreach (Order order in orders)
{
if (Array.Find(
custids, id => id == order.CustomerID) != null)
{
ordersForCustomer.Add(order);
}
}
return ordersForCustomer.ToArray();
}
}
Example for a WCF Service
The following code shows the operation definition in the service contract interface.
[OperationContract]
Order[] GetBulkOrdersForCustomers(string[] custids);
The following example shows the implementation of the method instance.
public Order[] GetBulkOrdersForCustomers(string[] custids)
{
if (custids == null)
{
return orders.ToArray();
}
else
{
List<Order> ordersForCustomer = new List<Order>();
foreach (Order order in orders)
{
if (Array.Find(
custids, id => id == order.CustomerID) != null)
{
ordersForCustomer.Add(order);
}
}
return ordersForCustomer.ToArray();
}
}
