大量のユーザー（4000ユーザー）に送信したいSMSので、次のメソッドをループに入れます：
protected int SendSMS(string url)
{
// Now to Send Data.
StreamWriter writer = null;
StringBuilder postData = new StringBuilder();
Uri myUri = new Uri(url);
postData.Append(HttpUtility.ParseQueryString(myUri.Query).Get("Username"));
postData.Append(HttpUtility.ParseQueryString(myUri.Query).Get("Password"));
postData.Append(HttpUtility.ParseQueryString(myUri.Query).Get("Sender"));
postData.Append(HttpUtility.ParseQueryString(myUri.Query).Get("Recipients"));
postData.Append(HttpUtility.ParseQueryString(myUri.Query).Get("MessageData"));
string webpageContent = string.Empty;
byte[] byteArray = Encoding.UTF8.GetBytes(postData.ToString());
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = webRequest.ContentLength = byteArray.Length;
writer = new StreamWriter(webRequest.GetRequestStream());
try
{
using (Stream webpageStream = webRequest.GetRequestStream())
{
webpageStream.Write(byteArray, 0, byteArray.Length);
}
using (HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse())
{
using (StreamReader reader = new StreamReader(webResponse.GetResponseStream()))
{
webpageContent = reader.ReadToEnd();
//TODO:parse webpagecontent: iF response contains "OK"
if (webpageContent.Contains("OK")) return 1;
else return 0;
}
}
//return 1;
}
catch (Exception ee)
{
ErrMapping.WriteLog(url);
string error = ee.Message + "<br><br>Stack Trace : " + ee.StackTrace;
ErrMapping.WriteLog(error);
return -1;
}
}
65 ユーザーなどの特定の数のユーザーの後sms、残りのユーザーには送信されず、
次の例外が発生します。
