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";

                }

                //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);
