I am learning Azure Events Hub. A simple application i have downloaded from this link https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-dotnet-standard-getstarted-send . But when i try to send message, its giving me this error:
10/23/2018 11:11:13 PM > Exception: Put token failed. status-code: 404, status-description: The messaging entity 'sb://demo.servicebus.windows.net/myTeam' could not be found. TrackingId:[My Tracking ID], SystemTracker:iot-bd-madness.servicebus.windows.net:IoT-BD-Madness, Timestamp:10/23/2018 5:11:18 PM.
In Azure Event Hub Dashboard all incoming requests (sending from console app) are visible with chart. but those are all request actually failed when i tried in console application
N.B:the given connectionstring is not real
public class Program
{
private static EventHubClient eventHubClient;
private const string EventHubConnectionString = "Endpoint=sb://iot-bd-madness.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
private const string EventHubName = "Iot-Bd-Madness";
public static void Main(string[] args)
{
MainAsync(args).GetAwaiter().GetResult();
}
private static async Task MainAsync(string[] args)
{
// Creates an EventHubsConnectionStringBuilder object from a the connection string, and sets the EntityPath.
// Typically the connection string should have the Entity Path in it, but for the sake of this simple scenario
// we are using the connection string from the namespace.
var connectionStringBuilder = new EventHubsConnectionStringBuilder(EventHubConnectionString)
{
EntityPath = EventHubName
};
eventHubClient = EventHubClient.CreateFromConnectionString(connectionStringBuilder.ToString());
await SendMessagesToEventHub(100);
await eventHubClient.CloseAsync();
Console.WriteLine("Press any key to exit.");
Console.ReadLine();
}
// Creates an Event Hub client and sends 100 messages to the event hub.
private static async Task SendMessagesToEventHub(int numMessagesToSend)
{
for (var i = 0; i < numMessagesToSend; i++)
{
try
{
var message = $"Message {i}";
Console.WriteLine($"Sending message: {message}");
await eventHubClient.SendAsync(new EventData(Encoding.UTF8.GetBytes(message)));
}
catch (Exception exception)
{
Console.WriteLine($"{DateTime.Now} > Exception: {exception.Message}");
}
await Task.Delay(10);
}
Console.WriteLine($"{numMessagesToSend} messages sent.");
}
}
}
