- T
A custom model type that implements ITableEntity or an instance of TableEntity.
Parameters
- filter
- String
Returns only entities that satisfy the specified OData filter.
For example, the following filter would filter entities with a PartitionKey of 'foo': "PartitionKey eq 'foo'".
The maximum number of entities that will be returned per page. Note: This value does not limit the total number of results if the result is fully enumerated.
- select
- IEnumerable<String>
An IEnumerable<T> of entity property names that selects which set of entity properties to return in the result set.
For example, the following value would return only the PartitionKey and RowKey properties: new[] { "PartitionKey, RowKey"}.
- cancellationToken
- CancellationToken
A CancellationToken controlling the request lifetime.
Returns
A Pageable<T> containing a collection of entity models serialized as type T.
Exceptions
The server returned an error. See Message for details returned from the server.

- T
A custom model type that implements ITableEntity or an instance of TableEntity.
Parameters
- filter
- Expression<Func<T,Boolean>>
Returns only entities that satisfy the specified filter expression.
For example, the following expression would filter entities with a PartitionKey of 'foo': e => e.PartitionKey == "foo".
The maximum number of entities that will be returned per page. Note: This value does not limit the total number of results if the result is fully enumerated.
- select
- IEnumerable<String>
An IEnumerable<T> of entity property names that selects which set of entity properties to return in the result set.
For example, the following value would return only the PartitionKey and RowKey properties: new[] { "PartitionKey, RowKey"}.
- cancellationToken
- CancellationToken
A CancellationToken controlling the request lifetime.
Returns
A Pageable<T> containing a collection of entity models serialized as type T.
