c# - 如何使用asp.net 4.0和c#在whatapp号码上发送消息

Question

我刚刚开发了一个具有发送whatsapp 消息功能的aspx 页面。在这里我只是发布我的代码。

 protected void btnSend_Click(object sender, EventArgs e)
    {
        string from = "919898683714";
        string to = txtTonumber.Text.Trim();//Sender Mobile
        string msg = txtMessage.Text.Trim();
        string password = WhatsAppApi.Register.WhatsRegisterV2.GetToken(from);

        WhatsApp wa = new WhatsApp(from, password, "Shalin",true,false);

        wa.OnConnectSuccess += () =>
        {
            ltrmessage.Text ="Connected to whatsapp...";

            wa.OnLoginSuccess += (phoneNumber, data) =>
            {
                wa.SendMessage(to, msg);
                ltrmessage.Text = "Message Sent...";
            };

            wa.OnLoginFailed += (data) =>
            {
                ltrmessage.Text = "Login Failed :" + data;
            };

            wa.Login();
        };

        wa.OnConnectFailed += (ex) =>
        {
            ltrmessage.Text = "Connection Failed...";
        };

        wa.Connect();
    }

但我仍然无法从此代码发送消息。

有没有人知道它...
