How to create a sample account in Salesforce using Salesforce API

Step 1: First create the salesforce API. Please refer to my my previous post.
Step 2: Try this sample code:

//Verify that we are already authenticated, if not
            //call the login function to do so

            try
            {
                Account account;
                sObject[] accs = new sObject[1];
                for (int j = 0; j < accs.Length; j++)
                {
                    account = new Account();
                    if (accounts == null)
                        account.AccountNumber = "0000000";
                    else
                        account.AccountNumber = "000000" + (accounts.Length + 1);                    
                    account.BillingCity = "CERRITOS";
                    account.BillingCountry = "US";
                    account.BillingState = "CA";
                    account.BillingStreet = "4322 Firstland";
                    account.BillingPostalCode = "90703";
                    account.Description = "Software and Services";
                    account.Fax = "511.111.1234";
                    account.Industry = "Software";
                    account.Name = "AmaSoft";
                    account.NumberOfEmployees = 40;
                    account.Ownership = "Amar";
                    account.Phone = "999.111.2222";
                    account.Website = "https://crmhunt.com";
                    accs[j] = account;
                }

                //create the object(s) by sending the array to the web service
                SaveResult[] sr = binding.create(accs);
                for (int j = 0; j < sr.Length; j++)
                {
                    if (sr[j].success)
                    {
                        Console.WriteLine("An account was create with an id of: " + sr[j].id);

                        //save the account ids in a class array
                        if (accounts == null)
                        {
                            accounts = new string[] { sr[j].id };
                        }
                        else
                        {
                            string[] tempAccounts = null;
                            tempAccounts = new string[accounts.Length + 1];
                            for (int i = 0; i < accounts.Length; i++)
                                tempAccounts[i] = accounts[i];
                            tempAccounts[accounts.Length] = sr[j].id;
                            accounts = tempAccounts;
                        }
                    }
                    else
                    {
                        //there were errors during the create call, go through the errors
                        //array and write them to the screen
                        for (int i = 0; i < sr[j].errors.Length; i++)
                        {
                            //get the next error
                            Error err = sr[j].errors[i];
                            Console.WriteLine("Errors were found on item " + j.ToString());
                            Console.WriteLine("Error code is: " + err.statusCode.ToString());
                            Console.WriteLine("Error message: " + err.message);
                        }
                    }
                }
                Console.WriteLine("\nHit return to continue...");
                Console.ReadLine();
            }
            catch (Exception ex)
            {
                Console.WriteLine("\nFailed to create account, error message was: \n"
                           + ex.Message);
                Console.Write("\nHit return to continue...");
                Console.ReadLine();
