如何从asp.net Web应用程序发送短信？
是否有必要从任何提供商处购买？
是否可以发送短信数量限制？
是否应该在不同的线程中发送SMS代码，以便在出现任何异常/延迟时主线程不会受到影响？
有人可以提供代码示例以及它如何工作的概念吗？

您需要利用某种电话提供商来实现这一目标。我个人是Twilio的忠实粉丝。它们是非常合理的费率，并API展示language specific API wrappers。特别是.NET有几个，包括官方的。
可以使用代码示例和演练here。
性能影响很小，因为您实际上构造了一个传递给Twilio端点的XML消息。繁重的工作不再是你的肩膀，因为它更像是传递和接收XML信息的系统。
希望有所帮助，这是一个非常容易使用的平台。

我使用了TcpClient，它实现了Disposable＆amp;创建了SmsHelper 类
public class SmsHelper
{
public void SendSms(string toNumber, string content)
{
bool connected;
TcpClient smsServer = OpenConnection("xyz.xy.x.xyz", xyzd, out connected);//require ip and port
if (connected)
{
string sms = content;
SendSmsToClient(smsServer, Properties.Settings.Default.FromNumber, toNumber, sms);
}
}
protected static TcpClient OpenConnection(string ip, int port, out bool connected)
{
string response = string.Empty;
string message = string.Empty;
TcpClient tcpClient = new TcpClient();
try
{
ASCIIEncoding ascEn = new ASCIIEncoding();
tcpClient.Connect(ip, port);
Stream stream = tcpClient.GetStream();
byte[] bb = new byte[100];
stream.Read(bb, 0, 100);
string connect = ascEn.GetString(bb);
if (!String.IsNullOrEmpty(connect))
{
//authenticating to smsServer
string str = "action: login\r\nusername: xxxxx\r\nsecret: integration\r\n\r\n";
byte[] ba = ascEn.GetBytes(str);
stream.Write(ba, 0, ba.Length);
stream.Flush();
byte[] resp = new byte[100];
stream.Read(resp, 0, 100);
response = ascEn.GetString(resp);
stream.Read(resp, 0, 100);
message = ascEn.GetString(resp);
if (response.Contains("Success") && message.Contains("Authentication accepted"))
{
Console.WriteLine("Authenticated");
stream.Flush();
connected = true;
return tcpClient;
}
else
{
Console.WriteLine("Credentials error Cant Authenticate");
tcpClient.Close();
connected = false;
return tcpClient;
}
}
connected = false;
return tcpClient;
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
connected = false;
return tcpClient;
}
protected static void CloseConnection(TcpClient client)
{
client.Close();
Console.WriteLine("Connection Closed process terminated...");
}
protected static void SendSmsToClient(TcpClient client, string fromNumber, string toNumber, string smsBody)
{
string response = string.Empty;
string message = string.Empty;
string eventMsg = string.Empty;
ASCIIEncoding asen = new ASCIIEncoding();
Stream stm = client.GetStream();
string smsSend = string.Format("action: smscommand\r\ncommand: gsm send sms {0} {1} \r\n\r\n", fromNumber, toNumber);
byte[] smsCmd = asen.GetBytes(smsSend);
stm.Write(smsCmd, 0, smsCmd.Length);
stm.Flush();
byte[] smsResp = new byte[1000];
stm.Read(smsResp, 0, 1000);
response = asen.GetString(smsResp);
if (!String.IsNullOrEmpty(response))

message = asen.GetString(smsResp);
if (!String.IsNullOrEmpty(message))
{
stm.Read(smsResp, 0, 1000);
eventMsg = asen.GetString(smsResp);
if (!String.IsNullOrEmpty(eventMsg))
{
String[] list = eventMsg.Split('\n');
foreach (string value in list)
{
if (value.StartsWith("--END"))
{
stm.Flush();
}
}
}
}
}
}
}
