Remarks

Message Availability

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

Usage

Pass an instance of this class to the Execute method, which returns an instance of RetrieveAttributeResponse.

Privileges and Access Rights

To perform this action, the caller must have privileges listed in RetrieveAttribute message privileges.

Notes for Callers

You can use either the LogicalName or the MetadataId to specify the attribute you want to retrieve.

Examples

The following example shows how to use this message. For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. For the complete sample, see the link later in this topic.

// Create the request
RetrieveAttributeRequest attributeRequest = new RetrieveAttributeRequest
{
    EntityLogicalName = Contact.EntityLogicalName,
    LogicalName = "new_string",
    RetrieveAsIfPublished = false
};

// Execute the request
RetrieveAttributeResponse attributeResponse =
    (RetrieveAttributeResponse)_serviceProxy.Execute(attributeRequest);

Console.WriteLine("Retrieved the attribute {0}.",
    attributeResponse.AttributeMetadata.SchemaName);
