Full Sample – C#

Demonstrates

This sample shows how to use the IOrganizationService.InitializeFromRequest message to create new records from an existing record.

Example



#region Initialize Account from Account
Console.WriteLine();
Console.WriteLine("  Initializing new Account from the initial Account");

// Create the request object
InitializeFromRequest initialize = new InitializeFromRequest();

// Set the properties of the request object
initialize.TargetEntityName = Account.EntityLogicalName.ToString();

// Create the EntityMoniker
initialize.EntityMoniker = _initialAccount.ToEntityReference();

// Execute the request
InitializeFromResponse initialized = 
    (InitializeFromResponse)_serviceProxy.Execute(initialize);

if (initialized.Entity != null)
    Console.WriteLine("  New Account initialized successfully");

Console.WriteLine();
#endregion

#region Initialize Opportunity from Lead
Console.WriteLine("  Initializing an Opportunity from the initial Lead");

// Create the request object
initialize.TargetEntityName = Opportunity.EntityLogicalName.ToString();

// Create the EntityMoniker
initialize.EntityMoniker = _initialLead.ToEntityReference();

// Execute the request
initialized =
    (InitializeFromResponse)_serviceProxy.Execute(initialize);

if (initialized.Entity != null &amp;&amp;
    initialized.Entity.LogicalName == Opportunity.EntityLogicalName)
{
    var opportunity = (Opportunity)initialized.Entity;
    Console.WriteLine("  New Opportunity initialized successfully (Name={0})",
        opportunity.Name);
}
