我寫了一個android的服務器。服務器工作良好，我成功地發送來自應用程序的模擬客戶端（SocketTest）的消息。 所以我用C＃寫了一個客戶端。 我試過我的客戶端對SocketTest（當然作爲服務器），它的工作。 到android的連接步驟似乎很好，我也不例外。 但我沒有看到我的Android設備中的消息。C＃Tcp客戶端不能發送消息到Android服務器
C＃代碼
{
public partial class sendSms : Form
{
TcpClient client;
NetworkStream ns;
public sendSms()
{
InitializeComponent();
}
private void Connect()
{
client = new TcpClient("192.168.14.76", 8080);
//client = new TcpClient("127.0.0.1", 8080);
ns = client.GetStream();
}
private void button1_Click(object sender, EventArgs e)
{
Connect();
}
private void sendBtn_Click(object sender, EventArgs e)
{
SendMessage();
}
private void SendMessage()
{
string sendMSG = msgTB.Text;
ns.Write(Encoding.UTF8.GetBytes(sendMSG), 0, sendMSG.Length);
ns.Flush();
}
}
}
