Examples
The following example provides an implementation of the OnNext method in a latitude/longitude tracking application. See the Example section of the IObserver<T> topic for the complete example.
public virtual void OnNext(Location value)
{
Console.WriteLine("{2}: The current location is {0}, {1}", value.Latitude, value.Longitude, this.Name);
}
member _.OnNext(value) =
printfn $"{name}: The current location is {value.Latitude}, {value.Longitude}"
Public Overridable Sub OnNext(ByVal value As Location) Implements System.IObserver(Of Location).OnNext
Console.WriteLine("{2}: The current location is {0}, {1}", value.Latitude, value.Longitude, Me.Name)
End Sub
Remarks
After an observer has called a provider's IObservable<T>.Subscribe method, the provider calls the observer's OnNext method to provide notifications.
