How do you exclude a property from being persisted in Azure Table storage?

Question

If I have a class like this:

    public class Facet : TableServiceEntity {     public Guid ParentId { get; set; }           public string Name { get; set; }     public string Uri{ get; set; }     public Facet Parent { get; set; } } 

Parent is derived from the ParentId Guid, and that relationship is intended to be filled in by my repository. So how do I tell Azure to leave that field alone? Is there an Ignore attribute of some type, or do I have to create an inherited class that provides those relationships instead?

Answer 1

Using latest Microsoft.WindowsAzure.Storage SDK (v6.2.0 and up), the attribute name has changed to IgnorePropertyAttribute :

public class MyEntity : TableEntity {      public string MyProperty { get; set; }       [IgnoreProperty]      public string MyIgnoredProperty { get; set; } } 

Answer 2

There is an attribute called WindowsAzure.Table.Attributes.IgnoreAttribute can be set on the property you want to exclude. Just use:

[Ignore] public string MyProperty { get; set; } 

It is a part of Windows Azure Storage Extensions, which you may download from: https://github.com/dtretyakov/WindowsAzure
