最近因為較寄送簡訊服務，比較一下，這一家最快，所以提供一下給大家 C# Source code.
Source Code:
<![CDATA[
WebClient wc4 = new WebClient();
string targetAddress4 = "https://rest.nexmo.com/sms/json";
wc4.Encoding = Encoding.UTF8;
wc4.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
NameValueCollection nc4 = new NameValueCollection();
nc4["api_key"] = YOUR_API_KEY;
nc4["api_secret"] = YOUR_API_SECRET;
nc4["to"] = mobile;
//必填
nc4["from"] = "no2studio";
nc4["text"] = YOUR_CONTENT;
//如果你要傳送中文，這一個地方必加，不然會出現很多 ?
nc4["type"] = "unicode";
byte[] bResult4 = wc4.UploadValues(targetAddress4, nc4);
string result = Encoding.Default.GetString(bResult4);
Console.Write(result);
]]>
其實重點在 記得中文的話要加入 type=unicode ，然後 如果你還沒有付錢記得 要先去 https://dashboard.nexmo.com/test-numbers 這裡加入測試帳號，不然你怎麼寄送都會被 Non White-listed destination - rejected
