با سلام
می خواهم که یک متن را از داخل یک سرور برای مثال با آدرس 192.168.0.1 به یک کلاینت به آدرس 192.168.0.2 بفرستم با پورت فرضی 8080 ،چگونه باید عمل کنم.
با تشکر

این کد دارای دو بخش Client و Server است.
این کد بخش Server :

using System.Windows.Forms;
using System.Net.Sockets;
using System.IO;
namespace TCPSocketServer
