I am trying to get a single entity provided only with a partition key. My current code is returning me a List from IEnumerable, but it doesn't seem very efficient to have a list when in fact it is only a single entity, and I have to do a foreach through it. Is there a way to achieve with without a list/IEnumerable?
var entities = currentTable.ExecuteQuery(new TableQuery<ItemEntity>()).Where(e => e.PartitionKey.Equals(itemEntity.xId)).ToList();
If you want to get a specified entity, you should provide Partition key and row key together.
But if you want to get a random entity, you should use the methods provided by GvS.
The result of the query is always an IEnumerable.
If you expect only a single result you can use:
var result = currentTable.ExecuteQuery(new TableQuery<ItemEntity>()).Where(e => e.PartitionKey.Equals(itemEntity.xId));
// First element from the result. Will fail when there is no element
var entity1 = result.First();
// First element from the result. Will give null when no element is available.
var entity2 = result.FirstOrDefault();
// First element from the result. Will fail when there is no element, or more as one element
var entity3 = result.Single();
// First element from the result. Will give null when one element is available, or fail (Exeption) when more as one.
var entity4 = result.SingleOrDefault();
