Using Property, Method, Class, Array Resize in C# .Net

        Using Property, Method, Class, Array Resize in C# .Net

First we create Class which name is Employee with property and method……..

using System;
using System.Windows.Forms;
namespace ArrayPropertywithClass
{
class Employee
{
private int IntEmpCode;

public int EmpCode
{
get { return IntEmpCode; }
set { IntEmpCode = value; }
}
private string StrFirstName;

public string FirstName
{
get { return StrFirstName; }
set { StrFirstName = value; }
}
private string StrLastName;

public string LastName
{
get { return StrLastName; }
set { StrLastName = value; }
}
private string StrEmailId;

public string EmailId
{
get { return StrEmailId; }
set { StrEmailId = value; }
}
private string StrPassword;

public string Password
{
get { return StrPassword; }
set { StrPassword = value; }
}

private string StrAddress;

public string Address
{
get { return StrAddress; }
set { StrAddress = value; }
}
private string StrCompanyName;

public string CompanyName
{
get { return StrCompanyName; }
set { StrCompanyName = value; }
}
private string StrSecurityQues;

public string SecurityQues
{
get { return StrSecurityQues; }
set { StrSecurityQues = value; }
}
private string StrAnswer;

public string Answer
{
get { return StrAnswer; }
set { StrAnswer = value; }
}
static Employee[] emp = new Employee[1];
static int index = 0;
int empcode;

// code for Add Employee with Array Resize Method…………

public int AddEmployee(string FirstName, string LastName, string EmailId, string Password, string Address, string Company, string SecuQuestion, string SecuAnswer)
{
Random rr=new Random();
empcode= rr.Next(100, 10000);
emp[index] = new Employee();
emp[index].EmpCode = empcode;
emp[index].FirstName = FirstName;
emp[index].LastName = LastName;
emp[index].EmailId = EmailId;
emp[index].Password = Password;
emp[index].Address = Address;
emp[index].CompanyName = Company;
emp[index].SecurityQues = SecuQuestion;
emp[index].Answer = SecuAnswer;
index++;
Array.Resize(ref emp, index + 1);
return empcode;

}

//  create method  for Search and Update by Employee Code  …………

int i ;
public Employee SearchUpdateByEmpCode(int EmpCode)
{
for ( i = 0; i < index ; i++)
{
if (emp[i].EmpCode == EmpCode)
{
return emp[i];
}
else
{
MessageBox.Show("CustomerID Doesn't Match Please enter correct id");
}
}
return null;
}

//  create method  for GetLogin  with EmailId and Password  …………

public Employee GetLogin(string EmailId,string Password)
{
for ( i = 0; i < emp.Length-1; i++)
{
if (emp[i].EmailId == EmailId && emp[i].Password == Password)
{
return emp[i];
}
else
{
MessageBox.Show("ID and Password not match please try again");
break;
}
}
return null;
}
}
}
