input string was not in a correct format. in asp.net

Question

I have a class in aspx.cs

in that i have a function like below

public static String GetMaritalStatus(String maritalStatus)
        {
            if (maritalStatus == null)
                return "";
            String[] maritalStatuses = new String[] { "--", "Single", "Married", "Divorced", "Widowed" };

            return maritalStatuses[int.Parse(maritalStatus)];
        }

When this function is called I am getting

input string was not in a correct format. Error

on the line

String[] maritalStatuses = new String[] { "--", "Single", "Married", "Divorced", "Widowed" };

What can be the reason.

Edited

String marital = GetMaritalStatus(02);

Answer 1

String marital = GetMaritalStatus(02);

02 is integer but your function GetMaritalStatus takes argument as string

use the below code to call your function

String marital = GetMaritalStatus("02");

Answer 2

This seems to happen on

return maritalStatuses[int.Parse(maritalStatus)];

I think 'maritalStatus' isn't an int when you try your code which gives you your error.
