Esempio

The following example shows how to use the Delete method to delete an account record (early bound). For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. You can find the complete sample in the sample code package in the folder SampleCode\CS\GeneralProgramming\EarlyBound\CRUDOperations.cs.

// Connect to the Organization service. 
// The using statement assures that the service proxy will be properly disposed.
using (_serviceProxy = new OrganizationServiceProxy(serverConfig.OrganizationUri, serverConfig.HomeRealmUri,serverConfig.Credentials, serverConfig.DeviceCredentials))
{
    // This statement is required to enable early-bound type support.
    _serviceProxy.EnableProxyTypes();

    CreateRequiredRecords();

    // Instantiate an account object.
    // See the Entity Metadata topic in the SDK documentation to determine 
    // which attributes must be set for each entity.
    Account account = new Account { Name = "Fourth Coffee" };

    // Create an account record named Fourth Coffee.
    _accountId = _serviceProxy.Create(account);
    Console.Write("{0} {1} created, ", account.LogicalName, account.Name);

    // Retrieve the account containing several of its attributes.
    ColumnSet cols = new ColumnSet(
        new String[] { "name", "address1_postalcode", "lastusedincampaign", "versionnumber" });

    Account retrievedAccount = (Account)_serviceProxy.Retrieve("account", _accountId, cols);
    Console.Write("retrieved ");

    // Retrieve version number of the account. Shows BigInt attribute usage.
    long? versionNumber = retrievedAccount.VersionNumber;

    if (versionNumber != null)
        Console.WriteLine("version # {0}, ", versionNumber);

    // Update the postal code attribute.
    retrievedAccount.Address1_PostalCode = "98052";

    // The address 2 postal code was set accidentally, so set it to null.
    retrievedAccount.Address2_PostalCode = null;

    // Shows usage of option set (picklist) enumerations defined in OptionSets.cs.
    retrievedAccount.Address1_AddressTypeCode = new OptionSetValue((int)AccountAddress1_AddressTypeCode.Primary);
    retrievedAccount.Address1_ShippingMethodCode = new OptionSetValue((int)AccountAddress1_ShippingMethodCode.DHL);
    retrievedAccount.IndustryCode = new OptionSetValue((int)AccountIndustryCode.AgricultureandNonpetrolNaturalResourceExtraction);

    // Shows use of a Money value.
    retrievedAccount.Revenue = new Money(5000000);

    // Shows use of a Boolean value.
    retrievedAccount.CreditOnHold = false;

    // Shows use of EntityReference.
    retrievedAccount.ParentAccountId = new EntityReference(Account.EntityLogicalName, _parentAccountId);

    // Shows use of Memo attribute.
    retrievedAccount.Description = "Account for Fourth Coffee.";

    // Update the account record.
    _serviceProxy.Update(retrievedAccount);
    Console.WriteLine("and updated.");                    

    DeleteRequiredRecords(promptforDelete);
}

The following example shows how to use the Delete method to delete an account record (late bound). For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. You can find the complete sample in the sample code package in the folder SampleCode\CS\GeneralProgramming\LateBound\CRUDOperationsDE.cs.

// Instaniate an account object.
Entity account = new Entity("account");

// Set the required attributes. For account, only the name is required. 
// See the Entity Metadata topic in the SDK documentatio to determine 
// which attributes must be set for each entity.
account["name"] = "Fourth Coffee";

// Create an account record named Fourth Coffee.
_accountId = _service.Create(account);

Console.Write("{0} {1} created, ", account.LogicalName, account.Attributes["name"]);

// Create a column set to define which attributes should be retrieved.
ColumnSet attributes = new ColumnSet(new string[] { "name", "ownerid" });

// Retrieve the account and its name and ownerid attributes.
account = _service.Retrieve(account.LogicalName, _accountId, attributes);
Console.Write("retrieved, ");

// Update the postal code attribute.
account["address1_postalcode"] = "98052";

// The address 2 postal code was set accidentally, so set it to null.
account["address2_postalcode"] = null;

// Shows use of Money.
account["revenue"] = new Money(5000000);

// Shows use of boolean.
account["creditonhold"] = false;

// Update the account.
_service.Update(account);
Console.WriteLine("and updated.");

// Delete the account.
bool deleteRecords = true;

if (promptForDelete)
{
    Console.WriteLine("\nDo you want these entity records deleted? (y/n) [y]: ");
    String answer = Console.ReadLine();

    deleteRecords = (answer.StartsWith("y") || answer.StartsWith("Y") || answer == String.Empty);
}

if (deleteRecords)
{
    _service.Delete("account", _accountId);

    Console.WriteLine("Entity record(s) have been deleted.");
}

Note

Message Availability

Questo messaggio funziona indipendentemente dal fatto che il chiamante sia connesso al server o offline.

Not all entity types support this message offline. See Supported Entities later in this topic.

Privileges and Access Rights

To perform this action, the caller must have privileges on the entity that is specified in the entityName parameter and access rights on the record that is specified in the id parameter. For a list of the required privileges, see Delete Privileges. When a record is deleted, all child records are also deleted. The entire deletion fails if the caller does not have the delete privilege or access rights for any of these records.

Notes for Callers

This method may cascade to related records according to the cascade configuration for each entity relationship. For a description of how actions on a parent record affect related records, see Cascading behavior.

Typically, you should only delete records that you entered by mistake. For some record types, you can deactivate or close the record instead.

You can use this method to delete any record of an entity that supports the Delete message, including records from custom entities.

For more information about the exceptions that can be thrown when you call this method, see Handle Exceptions in Your Code.

Supported Entities

Nella tabella seguente vengono mostrate le entità predefinite che supportano questo messaggio. Per le entità elencate di questo messaggio, nella colonna Disponibilità viene indicato Server se il chiamante deve essere connesso al server ed Entrambi se il chiamante può essere connesso oppure disconnesso dal server.
