Question

我需要知道如何使用Twilio API和C＃发送批量短信。我做了一些研究，表明我需要使用Twilio的Passthrough API，但我不理解。这是我编译的代码：

const string accountSid = "xxxxx";
const string authToken = "xxxxx";

TwilioClient.Init(accountSid, authToken);

MessageResource.Create(to: new PhoneNumber("+27" + txtTo.Text),
                       from: new PhoneNumber("xxxxx"),
                       body: txtMessage.Text,
                       provideFeedback: true,
                       statusCallback: new Uri("http://requestb.in/1234abcd"));

MessageBox.Show("Message sent successfully");

你不能这样做。您必须遍历订阅者列表并逐个发送或使用parallel foreach发送：

var subscriber = new Dictionary<string, string>() {
            {"+3912345678", "John"},
            {"+3917564237", "Mark"},
            {"+3915765311", "Ester"}
        };

// Iterate over subscribers
foreach (var person in subscriber)
{
    // Send a new outgoing SMS by POSTing to the Messages resource
    MessageResource.Create(
        from: new PhoneNumber("555-555-5555"), // From number, must be an SMS-enabled Twilio number
        to: new PhoneNumber(person.Key), // To number, if using Sandbox see note above
        // Message content
        body: $"Hello {person.Value}");

    Console.WriteLine($"Sent message to {person.Value}");
}

使用C＃Winforms在twilio中发送批量短信
