Esempio

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.

This code defines the AttributeMetadata for a number of different types of attributes and adds them to a List<AttributeMetadata>. At the end of the code, the CreateAttributeRequest class prepares the request, and the attribute is created by using the Execute method.

This code sample assumes that the current customization prefix is ‘new’ because that is the default customization prefix for the organization solution publisher. You should use the customization prefix for the solution publisher that makes sense for the solution context in which you work.

// Create storage for new attributes being created
addedAttributes = new List<AttributeMetadata>();

// Create a boolean attribute
BooleanAttributeMetadata boolAttribute = new BooleanAttributeMetadata
{
    // Set base properties
    SchemaName = "new_boolean",
    DisplayName = new Label("Sample Boolean", _languageCode),
    RequiredLevel = new AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.None),
    Description = new Label("Boolean Attribute", _languageCode),
    // Set extended properties
    OptionSet = new BooleanOptionSetMetadata(
        new OptionMetadata(new Label("True", _languageCode), 1),
        new OptionMetadata(new Label("False", _languageCode), 0)
        )

// NOTE: LookupAttributeMetadata cannot be created outside the context of a relationship.
// Refer to the WorkWithRelationships.cs reference SDK sample for an example of this attribute type.

// NOTE: StateAttributeMetadata and StatusAttributeMetadata cannot be created via the SDK.

    // Create the request.

    // Execute the request.
    _serviceProxy.Execute(createAttributeRequest);

    Console.WriteLine("Created the attribute {0}.", anAttribute.SchemaName);
}

Note

Message Availability

Affinché questo messaggio funzioni, il chiamante deve essere connesso al server.

Usage

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

Privileges and Access Rights

To perform this action, the caller must have the required privileges, as listed in CreateAttribute Privileges.

Notes for Callers

This message cannot be used to create a LookupAttributeMetadata attribute. Use the CreateOneToManyRequest message to create an entity relationship that includes the lookup attribute.

Supported Entities

You can only add attributes to customizable entities where the managed property CanCreateAttributes is true.
