- Source:
- TableClient.cs
Queries entities in the table.

- 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. If unspecified, the default value is 1000 for storage accounts and is not limited for Cosmos DB table API. 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
An AsyncPageable<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
- 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'".
