السلام عليكم
لدي مشلكة في تنفيد وجرب اكثر بي كود في بعض يشتغل ولكن الاغلب نفس الخطا   اضنها مشكلة بي اعدادة فيجول استديو او شيء ما  ويعطي  الخطاء في هذا السطر

كود :

Socket host = new Socket(AddressFamily.InterNetwork, SocketType.Raw
           ;(ProtocolType.Icmp,

اعتقد المشكلة في raw socket جرب كم من الحلول لكن لم اجد الحل وهذا كود البرنامج كامل

كود :

   try

} catch (SocketException)

Console.WriteLine("response from: {0}", ep.ToString());
Console.WriteLine(" Type {0}", response.Type);
Console.WriteLine(" Code: {0}", response.Code);
int Identifier = BitConverter.ToInt16(response.Message, 0);
int Sequence = BitConverter.ToInt16(response.Message, 2);
Console.WriteLine(" Identifier: {0}", Identifier);

string stringData = Encoding.ASCII.GetString(response.Message,

}
}

وهذا صورة الخطأ
