Dieses Thema enthält ein Beispiel, das veranschaulicht, wie Sie eine benutzerdefinierte Aktivitätsentität erstellen.

Das folgende Beispiel erstellt eine benutzerdefinierte Entität und legt die Eigenschaft IsActivity auf true fest. Für alle Aktivitäten muss PrimaryAttributeSchemaName auf Subject festgelegt werden, um dem allgemeinen Attribut ActivityPointer.Subject zu entsprechen, das von allen Aktivitäten verwendet wird.

 // The custom prefix would typically be passed in as an argument or 
 // determined by the publisher of the custom solution.
 String prefix = "new_";

 String customEntityName = prefix + "instantmessage";

 // Create the custom activity entity.
 CreateEntityRequest request = new CreateEntityRequest
 {
     HasNotes = true,
     HasActivities = false,
     PrimaryAttribute = new StringAttributeMetadata
     {
         SchemaName = "Subject",
         RequiredLevel = new AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.None),
         MaxLength = 100,
         DisplayName = new Label("Subject", 1033)
     },
     Entity = new EntityMetadata
     {
         IsActivity = true,
         SchemaName = customEntityName,
         DisplayName = new Label("Instant Message", 1033),
         DisplayCollectionName = new Label("Instant Messages", 1033),
         OwnershipType = OwnershipTypes.UserOwned,
         IsAvailableOffline = true,

     }
 };

 _serviceProxy.Execute(request);

 //Entity must be published

 // Add few attributes to the custom activity entity.
 CreateAttributeRequest fontFamilyAttributeRequest =
     new CreateAttributeRequest
{
    EntityName = customEntityName,
    Attribute = new StringAttributeMetadata
    {
        SchemaName = prefix + "fontfamily",
        DisplayName = new Label("Font Family", 1033),
        MaxLength = 100
    }
};
 CreateAttributeResponse fontFamilyAttributeResponse =
     (CreateAttributeResponse)_serviceProxy.Execute(
     fontFamilyAttributeRequest);

 CreateAttributeRequest fontColorAttributeRequest =
     new CreateAttributeRequest
 {
     EntityName = customEntityName,
     Attribute = new StringAttributeMetadata
     {
         SchemaName = prefix + "fontcolor",
         DisplayName = new Label("Font Color", 1033),
         MaxLength = 50
     }
 };

     (CreateAttributeResponse)_serviceProxy.Execute(
     fontColorAttributeRequest);

     Attribute = new IntegerAttributeMetadata
     {
         SchemaName = prefix + "fontSize",
         DisplayName = new Label("Font Size", 1033)
     }
 };
 CreateAttributeResponse fontSizeAttributeResponse =
     (CreateAttributeResponse)_serviceProxy.Execute(
     fontSizeAttributeRequest);

' determined by the publisher of the custom solution.
Dim prefix As String = "new_"

Dim customEntityName As String = prefix & "instantmessage"

' Create the custom activity entity.
Dim request As CreateEntityRequest = New CreateEntityRequest With {
