本主题包含演示如何创建自定义活动实体的示例。

以下示例插件自定义实体，并将 IsActivity 属性设置为 true。 所有活动都必须将 PrimaryAttributeSchemaName 设置为“Subject”，以使其对应于所有活动使用的通用 ActivityPointer.Subject 属性。

 // 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);

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

     }
 };

     (CreateAttributeResponse)_serviceProxy.Execute(
     fontSizeAttributeRequest);
