Namespace: Microsoft.Xrm.Sdk
Assembly: Microsoft.Xrm.Sdk (in Microsoft.Xrm.Sdk.dll)

Syntax

[OperationContractAttribute]
[FaultContractAttribute(typeof(OrganizationServiceFault))]
void Delete(
    string entityName,
    Guid id
)

<OperationContractAttribute>
<FaultContractAttribute(GetType(OrganizationServiceFault))>
Sub Delete (
    entityName As String,
    id As Guid
)

Parameters

entityName
Type: System.String

Type: String. The logical name of the entity that is specified in the entityId parameter.

id
Type: System.Guid

Type: Guid. The ID of the record that you want to delete.

Remarks

Message Availability

This message works regardless whether the caller is connected to the server or 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 message 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

The following table shows the default entities that support this message. For the listed entities of this message, the Availability column shows Server if the caller must be connected to the server and shows Both if the caller can be either connected to, or disconnected from, the server.

Examples

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.
