FormateException Was UnHandled

Question

  i wrote a code in c# language as console application, i got error at GETTING INPUT IN ADDRESS AREA, see below mentioned comment,

public class bloodgroupdetails

{

int[] emp_code = new int[10];

string[] emp_name = new string[30];

int[] age = new int[5];

char[] address = new char[30];

char[] blood_grp = new char[10];

int[] salary = new int[10];

public int n, i;

public void getdata()

{

Console.WriteLine("\n how many employee details are going to be get:");

n = int.Parse(Console.ReadLine());

for (i = 0; i < n; i++)

{

Console.WriteLine("\nEnter the employee code:");

emp_code[i] = int.Parse(Console.ReadLine());

 

Console.WriteLine("\n enter the employee name:");

emp_name[i] = Console.ReadLine();

Console.WriteLine("\n enter the age:");

age[i] = Convert.ToInt32(Console.ReadLine());

Console.WriteLine("\n enter the address:");

address[i] = Convert.ToChar(Console.ReadLine());  //// when i get input from user at runtime it show FORMATEEXCEPTION WAS UNHANDLED and                                                                                                       i cannot go forward to get furture input.

Console.WriteLine("\n enter the blood group:");

blood_grp[i] = char.Parse(Console.ReadLine());

Console.WriteLine("\n enter the salary:");

salary[i] = int.Parse(Console.ReadLine());

}
