Public Function Retrieve (entityName As String, id As Guid, columnSet As ColumnSet) As Entity

Parameters

entityName: String

The logical name of the table for the record that is specified in the id parameter.

id: Guid

The ID of the record that you want to retrieve.

columnSet: ColumnSet

A query that specifies the set of columns, or attributes, to retrieve.

Returns

Entity

The requested entity.

Attributes: FaultContractAttribute OperationContractAttribute

Examples

The following example shows four different ways to set the parameters for the Retrieve(String, Guid, ColumnSet) method depending on common ways you might reference a record that you want to retrieve.

When using the generated early-bound Account class, you can use the EntityLogicalName property or the Entity.LogicalName property to set the entityName parameter. Learn more about generating early-bound classes for the SDK for .NET
When using the late-bound Entity class, you can use the Entity.LogicalName property to set the entityName parameter.
When using a reference to a record defined with the EntityReference class, you can use the EntityReference.LogicalName property to set the entityName parameter.
If you only have the ID value and know the type of record, you can set the entityName parameter to a string value that corresponds to the EntityMetadata.LogicalName property. In this case, that value is 'account'.

For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface instance.

{

      ColumnSet columns = new("name", "primarycontactid", "createdby", "createdon");

      // Early bound example
      Account retrievedAccount1 = (Account)service.Retrieve(entityName: Account.EntityLogicalName, 
         id: earlyBoundAccount.Id, 
         columnSet: columns);
      // Late bound example
      Entity retrievedAccount2 = service.Retrieve(entityName: lateBoundAccount.LogicalName, 
         id: lateBoundAccount.Id, 
         columnSet: columns);
      // Account reference 
      Entity retrievedAccount3 = service.Retrieve(entityName: accountReference.LogicalName, 
         id: accountReference.Id, 
         columnSet: columns);
      // Guid ID
      Entity retrievedAccount4 = service.Retrieve(entityName: "account", 
         id: accountId, 
         columnSet: columns);
}

Remarks

Learn how to retrieve a table row using the SDK for .NET.

Privileges and Access Rights

To perform this action, the caller must have Read privileges on the table that is specified in the entityName parameter and Read access rights on the record that is specified in the id parameter. Learn more about how to verify access with code.

Notes for Callers

The returned record contains values for the specified properties in the columnSet parameter for which the calling user has access rights.

Pass null for the columnSet parameter to retrieve only the primary key. If the columnSet includes attributes where IsValidForRead is false, they are ignored.

To retrieve a record and its related records in a single transaction, use the RetrieveRequest class. Learn how to retrieve records with related rows.
