Azure Table Storage: Ignoring a property of a TableEntity when using the Azure.Data.Tables package - azure

Question

I am using the new Azure.Data.Tables library from Microsoft to deal with Azure Table Storage. With the old library when you had an entity that implemented ITableEntity and you had a property that you did not want to save to the storage table you would use the [IgnoreProperty] annotation. However, this does not seem to be available on the new library.
What would be the equivalent on the Azure.Data.Tables package or how do you now avoid saving a property to table storage now?
This is the class I want to persist:
public class MySpatialEntity : ITableEntity
{
public int ObjectId { get; set; }
public string Name { get; set; }
public int MonitoringArea { get; set; }
//This is the property I want to ignore because table storage cannot store it
public Point Geometry { get; set; }
//ITableEntity Members
public virtual string PartitionKey { get => MonitoringArea.ToString(); set => MonitoringArea = int.Parse(value); }
public virtual string RowKey { get => ObjectId.ToString(); set => ObjectId = int.Parse(value); }
public DateTimeOffset? Timestamp { get; set; }
public ETag ETag { get; set; }
}

Answer 1

As of version 12.2.0.beta.1, Azure.Data.Tables table entity models now support ignoring properties during serialization via the [IgnoreDataMember] attribute and renaming properties via the [DataMember(Name="<yourNameHere>")] attribute.
See the changelog here.

Answer 2

I don't think there's anything like [IgnoreProperty] available as of now (at least with version 12.1.0).
I found two Github issues which talk about this:
https://github.com/Azure/azure-sdk-for-net/issues/19782
https://github.com/Azure/azure-sdk-for-net/issues/15383
What you can do is create a custom dictionary of the properties you want to persist in the entity and use that dictionary for add/update operations.
Please see sample code below:
using System;
using System.Collections.Generic;
using System.Drawing;
using Azure;
using Azure.Data.Tables;
namespace SO68633776
{
class Program
{
private static string connectionString = "connection-string";
private static string tableName = "table-name";
static void Main(string[] args)
{
MySpatialEntity mySpatialEntity = new MySpatialEntity()
{
ObjectId = 1,
Name = "Some Value",
MonitoringArea = 2
};
TableEntity entity = new TableEntity(mySpatialEntity.ToDictionary());
TableClient tableClient = new TableClient(connectionString, tableName);
var result = tableClient.AddEntity(entity);
}
}
public class MySpatialEntity: ITableEntity
{
public int ObjectId { get; set; }
public string Name { get; set; }
public int MonitoringArea { get; set; }
//This is the property I want to ignore because table storage cannot store it
public Point Geometry { get; set; }
//ITableEntity Members
public virtual string PartitionKey { get => MonitoringArea.ToString(); set => MonitoringArea = int.Parse(value); }
public virtual string RowKey { get => ObjectId.ToString(); set => ObjectId = int.Parse(value); }
public DateTimeOffset? Timestamp { get; set; }
public ETag ETag { get; set; }
public IDictionary<string, object> ToDictionary()
{
return new Dictionary<string, object>()
{
{"PartitionKey", PartitionKey},
{"RowKey", RowKey},
{"ObjectId", ObjectId},
{"Name", Name},
{"MonitoringArea", MonitoringArea}
};
}
}
}
