Can any one have sample that will help me to send/receive data to/from Azure Event Hub.

What I have tried:

private static EventHubClient eventHubClient;
        private const string EhConnectionString = "Endpoint=sb://-----.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=-------";

private const string EhEntityPath = "------";

private async Task MainAsync()
        {
            try
            {
                var connectionStringBuilder = new EventHubsConnectionStringBuilder(EhConnectionString)
                {
                    EntityPath = EhEntityPath
                };

                eventHubClient = EventHubClient.CreateFromConnectionString(connectionStringBuilder.ToString());
                await SendMessagesToEventHub();
                await eventHubClient.CloseAsync();
            }
            catch (Exception ex)
            {
                textBlock.Text = ex.Message;
            }
        }

private async Task SendMessagesToEventHub()
        {
            int avgSpeed = 10; // m/s
            Random rand = new Random();
            int seq = 0;
            while (true)
            {
                int currentSpeed = avgSpeed + rand.Next() * 4 - 2;
                var data = new
                {
                    guid = "guid_1",
                    organization = "Elpis_IT_2",
                    displayname = "Telemetry_2",
                    location = "Elpis_Lab_2",
                    measurename = "mn_2",
                    unitofmeasure = "n",
                    timecreated = DateTime.Now.ToString() + "__" + (++seq),
                    value = rand.Next()
                };
                var message = JsonConvert.SerializeObject(data); 
                try
                {
                    await eventHubClient.SendAsync(new EventData(Encoding.UTF8.GetBytes(message)));
                    textBlock1.Text = $"Sending message: {message}";
                    await Task.Delay(10);
                    //number--;
                }
                catch (Exception ex)
                {
                    textBlock2.Text = ex.Message;
                }
            }
        private void btnSend_Click(object sender, RoutedEventArgs e)
        {
            MainAsync();
        }

推荐答案

发送消息：{message};
await Task.Delay（ 10 ）;
// number - ;
}
catch （Exception ex）
{
textBlock2.Text = ex.Message;
}
}
私有 void btnSend_Click（ object sender，RoutedEventArgs e）
{
MainAsync（）;
}

"Sending message: {message}"; await Task.Delay(10); //number--; } catch (Exception ex) { textBlock2.Text = ex.Message; } } private void btnSend_Click(object sender, RoutedEventArgs e) { MainAsync(); }
