Sendgrid-csharp: sg.client.mail.send.post - the result do not have StatusCode?! Possible change in the api?

[velchev]

I am using SendGrid version: <package id="SendGrid.CSharp.HTTP.Client" version="3.0.0" targetFramework="net461" />

dynamic response = sg.client.mail.send.post(requestBody: requestBody);
Log.Info(string.Format("Posted Email:{0} requestBody:{1}", toEmail, requestBody));
Log.Info(response.StatusCode);

This code started to give exceptions after 3-4 months of using it. The issue was that the dynamic response didn't contain StatusCode. Let me know if I am doing something that is not correct. I think someone from the team sow that there is a new version of the sendgrid api and updated it then this exception was introduced started to break.

Hello @velchev,

Thanks for reaching out to us!

I was able to duplicate this issue with this code (the GET Collection worked as expected, but the crash happened when trying to POST):

using System;
using SendGrid.CSharp.HTTP.Client;
using System.Collections.Generic;
using System.Threading.Tasks;
using Newtonsoft.Json;

namespace ConsoleApplication11
{
    class Program
    {
        static void Main(string[] args)
        {
            Execute().Wait();
        }

        static async Task Execute()
        {
            string apiKey = Environment.GetEnvironmentVariable("SENDGRID_APIKEY", EnvironmentVariableTarget.User);
            String host = "https://api.sendgrid.com";
            Dictionary<String, String> globalRequestHeaders = new Dictionary<String, String>();
            globalRequestHeaders.Add("Authorization", "Bearer " + apiKey);
            globalRequestHeaders.Add("Content-Type", "application/json");
            String version = "v3";
            dynamic client = new Client(host: host, requestHeaders: globalRequestHeaders, version: version);

            // GET Collection
            string queryParams = @"{
                'limit': 100
            }";
            Dictionary<String, String> requestHeaders = new Dictionary<String, String>();
            requestHeaders.Add("X-Test", "test");
            dynamic response = await client.api_keys.get(queryParams: queryParams, requestHeaders: requestHeaders);
            Console.WriteLine(response.StatusCode);
            Console.WriteLine(response.Body.ReadAsStringAsync().Result);
            Console.WriteLine(response.Headers.ToString());
            Console.ReadLine();

            string data = @"{
              'personalizations': [
                {
                  'to': [
                    {
                      'email': '[email protected]'
                    }
                  ],
                  'subject': 'Hello World from the SendGrid C# Library!'
                }
              ],
              'from': {
                'email': '[email protected]'
              },
              'content': [
                {
                  'type': 'text/plain',
                  'value': 'Hello, Email!'
                }
              ]
            }";
            Object json = JsonConvert.DeserializeObject<Object>(data);
            response = client.mail.send.post(requestBody: json.ToString());
            Console.WriteLine(response.StatusCode);
            Console.ReadLine();
        }
    }
}

I have added this to our backlog for further investigation.

Alternatively, you can use the official SendGrid SDK: https://www.nuget.org/packages/SendGrid (it depends on SendGrid.CSharp.HTTP.Client).

¿Can you please stop using dynamics? They are hard to maintain and debug. Very bad practice. As an angry customer, I won't migrate to V3 because of those painful dynamics objects out of control.

[Jericho]

@cpsaez-Lendsum please have a look at StrongGrid, it's a strongly typed client for SendGrid's API which means that it does not use dynamic at all. Hopefully you'll find it helpful.

[cpsaez]

Very helpfull Jericho. Your library should be the official library. Stronger than the official.

[velchev]

The library is useful if you are constantly looking at the SendGrid WebAPI... and predicting what should be the next thing you add - crazy. sg.client.mail then what?! Will check Jericho's suggestion but for now no time to change to a new api wrapper.

[chadwackerman]

Amazon SES charges $30 to send 300,000 emails and SendGrid charges $199.95. I don't know how SendGrid expects to stay in business if they can't provide proper SDKs for their "enhanced" features.

@cpsaez-Lendsum, @velchev,

The next version of this library (see the v9beta branch) has removed the dynamics and is now strongly typed. The beta is planned to be released within weeks. Thanks!

@Jericho's solution is solid and a good alternative until then.

@cpsaez-Lendsum, @velchev,

Have a chance to give the v9 SDK (now the official current version) a spin?

I have a VS2013 environment trying to add Sendgrid because of Azure, it is causing a lot of pain and the build breaking. I am trying my luck with Sendgrid 6.3.0 (already had to upgrade .net from 4.5.0. to 4.5.2 to because of it) but I can get neither SendGrid.Helpers.Mail [Namespace Helpers does not exist]; nor the SendGridClient() variable to resolve. All I need is a quick way to send out emails under Azure!

Also do I need to install SendGridClient -Version 1.1.0 in addition to SendGrid 6.3.0 or is the former obsolete? The many many many different versions (and few working examples) for sending emails are super confusing.

Why can I not use:
using SendGrid.Helpers.Mail;
How do I send mails with the "plain" libraryt (6.3.0)?

[thinkingserious]

Hello @RealRaven2000,

Could you use the latest version of this SDK (v9)? v6.3.0 is no longer supported.

With Best Regards,

Elmer

[RealRaven2000]

I cannot upgrade my Visual Studio Ultimate it is stuck at 2013. Surely there must be a working example of Sendgrid that works with that? The library is around for a while I worked my way backwards from 8 and 7 and found 6.3.0 is barely supported in VS2013.

Can I use SendGridMail.dll for sending mail?

@RealRaven2000,

Moving this conversation here: https://github.com/sendgrid/sendgrid-csharp/issues/420

[thinkingserious]

@RealRaven2000,

If you just want to stick with v6.3.0, here is the documentation: https://github.com/sendgrid/sendgrid-csharp/tree/b27983a8f3d84a9d28972f2720cca0315ad9fe32
