            API p = new API();
            p.firstname = strarray[0];
            p.lastname = strarray[1];
            p.mobilenumber = strarray[2];
            return p;

        }


    }

---I return an object from Split function.
--- object obj= b1.Split(strdetail);

How to iterate through the obj.
-- I was trying foreach. But foreach cannot be used with objects. 

Kindly suggest

Solution 1

Why do you need to convert it into object when the split returns array string.

Try this

string strdetail = "Anurag Nayak 8585916787";
B b1 = new B();
string[] str= b1.Split(strdetail);

then to use iteration use like this:-

for(int i=0;i<str.length;i++)>
{
    //do your work
}

Solution 2

Try this

C#

string strdetail = "Anurag Nayak 8585916787";
           B b1 = new B();
           object obj = b1.Split(strdetail);
           API api = obj as API; // casting the object to Type API
           string firstname = api.firstname;
           string lastname = api.lastname;
           string mobieno = api.mobilenumber;

Solution 3

Class B seems redundant, you could simplify this to something like:

C#

namespace oops1
{
    class Program
    {
        static void Main(string[] args)
        {

            string strdetail = "Anurag Nayak 8585916787";
            string[] details = strdetail.Split(' ');
            API p = new API(details);
        }
    }


   public class API
   {
       public string Firstname
       {
           get;
           set;
       }
       public string Lastname;
       {
           get;
           set;
       }
       public string Mobilenum;
       {
           get;
           set;
       }

       public API(string [] details)
       {
           Firstname = details[0];
           Lastname = details[1];
           Mobilenum = details[2];
       }
    }
}

You can now print any of the fields with a statement such as

C#

Console.WriteLine("name is: {0} {1}", p.Firstname, p.Lastname);

That is really cool. But i have one doubt. As you said i corrected in this way.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace oops1
{
class Program
{
static void Main(string[] args)
{

string strdetail = "Anurag Nayak 8585916787";
string[] details = strdetail.Split(' ');
API p = new API(details);
}
}

}

----------------
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace oops1
{
public class API
{
string _firstname;
string _lastname;
string _mobilenum;

string[] words;
public API(string [] details)
{
_firstname = details[0];
_lastname = details[1];
_mobilenum = details[2];

}
}
}
--------------------------------
In the Main method now after this line how to retrieve here:

API p = new API(details);

--i i put a breakpoint and reach till the above line(over p) ...i could see the details.
now i want to print in the console all the details.
