Question

Hi
i have created a Generic Array that works fine for Int,String, Float or even my Own type named Customers.

Generic Array has functions Add(), Sort(), ShowAll() thats working fine for Int, String, and even Customer Type
except when i try to showAll() method for CustomerType that shows all the values that i have added through ADD() method.

output is something like
GenericArray.Customer

not the values where as i wanted to have the values .

i have solved it through

public class GArray<T> where T : Customer

but now i cant create Generic Array of type Int,Float .

here is the ADD and ShowAll method of Class

public void Add(T temp)
        {

            if (index >= values.Length)
            {
                T[] tempArray = new T[values.Length + 1];
                Array.Copy(values, tempArray, values.Length);
                values = tempArray;
            }
            values[index] = temp;
            index++;  
        }

 public void ShowAll()
    {
        for (int i = 0; i < values.Length; i++)
        {
            Console.WriteLine(values[i]);                
        }
    }

the values m adding

 static void Main(string[] args)
        {                        
            GArray<Customer> customers = new GArray<Customer>(3);
            customers.Add(new Customer(101, "xyz"));
            customers.Add(new Customer(59, "abc"));

            customers.ShowAll();
            }

i have talked with my frnd and he said that i have to create indexer my self . can some one help me how can i create indexer in this case that works fine for customerType or any Type.

I think,If I understand the question (output is something like GenericArray.Customer, not the values where as i wanted to have the values) you should add in Customer definition:

public override string ToString()
{
    // return something you want to show to identify your customer
    // e.g. return Name;  
    return ...           
}

I explain: when you use Console.WriteLine(values[i]) you tell C# to write to console Customer object… and it writes out then name of the class, as it’s the default behaviour.
Defining in Customer class the default string to be converted to makes what you please…
