public virtual System.Threading.Tasks.Task<System.Data.Entity.Spatial.DbGeometry> GetGeometryAsync (int ordinal, System.Threading.CancellationToken cancellationToken);abstract member GetGeometryAsync : int * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Entity.Spatial.DbGeometry>
override this.GetGeometryAsync : int * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Entity.Spatial.DbGeometry>Parameters
- ordinal
- Int32
The ordinal of the data record column that contains the provider-specific geometry data.
- cancellationToken
- CancellationToken
A CancellationToken to observe while waiting for the task to complete.
Returns
A task that represents the asynchronous operation. The task result contains the instance of DbGeometry at the specified column value.
- Attributes
Remarks
Providers should override with an appropriate implementation. The default implementation invokes the synchronous GetGeometry(Int32) method and returns a completed task, blocking the calling thread.
