Azure Table Storage - a column of a TableEntity table with a different name

Question

I use Azure table storage as my data stream for my semantic log application block. When I call the log, which should be written by my user EventSource, I get columns similar to ff .:

• Eventid
• Payload_username
• Opcode

I can get these columns by creating a class TableEntitythat exactly matches the column names (except EventIdfor some reason):

public class ReportLogEntity : TableEntity
{
    public string EventId { get; set; }
    public string Payload_username { get; set; }
    public string Opcode { get; set; }
}

However, I would like to save the data in these columns in properties with different names in mine TableEntity:

public class ReportLogEntity : TableEntity
{
    public string Id { get; set; } // maps to "EventId"
    public string Username { get; set; } // maps to "Payload_username"
    public string Operation { get; set; } // maps to "Opcode"
}

Is there an attribute / attribute that I can use to allow me to have a column name different from the property name TableEntity?

ReadEntity WriteEntity ITableEntity, .

    public class ReportLogEntity : TableEntity
    {
        public string PartitionKey { get; set; }
        public string RowKey { get; set; }
        public string Id { get; set; } // maps to "EventId"
        public string Username { get; set; } // maps to "Payload_username"
        public string Operation { get; set; } // maps to "Opcode"

        public override void ReadEntity(IDictionary<string, EntityProperty> properties, OperationContext operationContext)
        {
            this.PartitionKey = properties["PartitionKey"].StringValue;
            this.RowKey = properties["RowKey"].StringValue;
            this.Id = properties["EventId"].StringValue;
            this.Username = properties["Payload_username"].StringValue;
            this.Operation = properties["Opcode"].StringValue;
        }

        public override IDictionary<string, EntityProperty> WriteEntity(OperationContext operationContext)
        {
            var properties = new Dictionary<string, EntityProperty>();
            properties.Add("PartitionKey", new EntityProperty(this.PartitionKey));
            properties.Add("RowKey", new EntityProperty(this.RowKey));
            properties.Add("EventId", new EntityProperty(this.Id));
            properties.Add("Payload_username", new EntityProperty(this.Username));
            properties.Add("Opcode", new EntityProperty(this.Operation));
            return properties;
        }
    }
