using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
namespace PHIndex
{
public partial class MainFrm : Form
{
CTeleRecord phoneRecord;
public MainFrm()
{
InitializeComponent();
phoneRecord = new CTeleRecord();
phoneRecord.errorEvnt += new errorEventHandler(ErrorHnd);
}
private void button1_Click(object sender, EventArgs e)
{
phoneRecord.GSName = textBox1.Text;
phoneRecord.GShomeNumber = textBox2.Text;
FileStream outPutSt = new FileStream("test.bin", FileMode.Create, FileAccess.Write);
BinaryFormatter outBinFormater = new BinaryFormatter();
outBinFormater.Serialize(outPutSt, phoneRecord);
}
private void button2_Click(object sender, EventArgs e)
{
BinaryFormatter inpuBinFormater = new BinaryFormatter();
FileStream inPutSt = new FileStream("test.bin", FileMode.Open, FileAccess.Read);
phoneRecord = (CTeleRecord)inpuBinFormater.Deserialize(inPutSt);
textBox1.Text= phoneRecord.GSName;
textBox2.Text= phoneRecord.GShomeNumber;
}
void ErrorHnd(object sender, myEventsArg e)

MessageBox.Show(e.GetErrorMessage,"Error Code"+e.GetErrorCode);
