Code Snippet: Implementing a ChangedIdEnumerator
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 ChangedIdEnumerator method instance in a .NET connectivity assembly and in a Web service.
Example for a .NET Connectivity Assembly
public CustomerVersion[] GetCustomerChangedIDs(String[] ids)
{
List<CustomerVersion> custverList = new List<CustomerVersion>();
foreach (Customer customer in customers)
{
if (Array.Find(ids, id =>
id == customer.CustomerID && !customer.IsDeleted) != null)
{
custverList.Add(new CustomerVersion()
{
CustomerID = customer.CustomerID,
Version = customer.Version
});
}
}
return custverList.ToArray();
}
Example for an ASP.NET Web Service
[WebMethod]
public CustomerVersion[] GetCustomerChangedIDs(String[] ids)
{
List<CustomerVersion> custverList = new List<CustomerVersion>();
foreach (Customer customer in customers)
{
if (Array.Find(ids, id =>
id == customer.CustomerID && !customer.IsDeleted) != null)
{
custverList.Add(new CustomerVersion()
{
CustomerID = customer.CustomerID,
Version = customer.Version
});
}
}
return custverList.ToArray();
}
Example for a WCF Service
The following code shows the operation definition in the service contract interface.
[OperationContract]
CustomerVersion[] GetCustomerChangedIDs(string[] ids);
The following example shows the implementation of the method instance.
public CustomerVersion[] GetCustomerChangedIDs(String[] ids)
{
List<CustomerVersion> custverList = new List<CustomerVersion>();
foreach (Customer customer in customers)
{
if (Array.Find(ids, id =>
id == customer.CustomerID && !customer.IsDeleted) != null)
{
custverList.Add(new CustomerVersion()
{
CustomerID = customer.CustomerID,
Version = customer.Version
});
}
}
return custverList.ToArray();
}
