c# search array - No overload for method

I keep getting an error when trying to compile my program, i'm having issues with the search part of the code. Not sure what i'm doing wrong.

Here is the error I'm getting when compiling:

week3.cs(97,17): error CS1501: No overload for method 'searchAccounts' takes 1 arguments week3.cs(27,21): (Location of symbol related to previous error)

Here is my entire code:

using System;

class Accounts
    {
        // private class members
        const int arrayLength = 5;
        private int [] Account = new int[arrayLength]; //create arrays
        private double [] AcctBalance = new double[arrayLength];
        private string [] LastName = new string[arrayLength];

        // fill all three parallel arrays with input
        public void fillAccounts(int[] Account, double[] AcctBalance, string[] accountNameArray)
        {
            int arrayLength = 0;
            for (int i = 0; i < Account.Length; i++)
            {
                Console.Write("Enter integer account number ");
                Account[arrayLength] = Convert.ToInt32(Console.ReadLine());
                Console.Write("Enter account balance ");

            accountNum = Convert.ToInt32(Console.ReadLine());

                Console.WriteLine("The program will now close");

            //internal documentation
        } //end main
    }

Any help would be greatly appreciated.

The line :

accounts.searchAccounts(Account);

Is calling searchAccounts with one parameter.

whereas searchAccounts has this requirement:

public void searchAccounts(int[] Account, double[] AccountBalance, string[] LastName)

Replace

accounts.searchAccounts(Account);

with

accounts.searchAccounts(Account, AcctBalance, LastName);

As declared right now searchAccounts needs three parameters, not just the one you are trying to pass - the other two are not optional (although you don't seem to use the account balance at all in searchAccounts())
