C# c搜索数组-方法没有重载

当我试图编译我的程序时，我总是遇到一个错误，我在代码的搜索部分遇到了问题。不知道我做错了什么

以下是编译时出现的错误：

周3.cs97,17:错误CS1501:否 方法“searchAccounts”的重载 采取1周3.cs27,21： 相关符号的位置 先前错误

这是我的全部代码：

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 ");
                AcctBalance[arrayLength] = Convert.ToDouble(Console.ReadLine());
                Console.Write("Enter account holder last name ");

            } //end for

        } //end fillAccounts method

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

            bool isValid = false;
            int x = 0;

            Console.Write("Please enter the account number you wish to search for ");
            accountNum = Convert.ToInt32(Console.ReadLine());

            while (x < Account.Length && accountNum != Account[x])
                ++x;

                    + " and the account holder is " + LastName[x]);
            else
                Console.WriteLine("No such account as {0}", accountNum);


        }

        public void averageAccounts(int[] Account, double[] AcctBalance)
        {
            // compute and display average of all 5 bal as currency use length.
            int balanceCount = 0;

            //internal documentation
        } //end main
    }

任何帮助都将不胜感激。

替换

accounts.searchAccounts(Account);

与

正如目前所声明的，searchAccounts需要三个参数，不仅仅是您试图传递的参数-其他两个参数不是可选的，尽管您似乎根本不使用searchAccounts中的帐户余额行：

accounts.searchAccounts(Account);

正在使用一个参数调用searchAccounts

鉴于searchAccounts有此要求：

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

---

有点离题，但我强烈建议您创建一个Account类并使用list或Dictionary类型的列表。这不仅是更好的OO实践，您还可以随时使用Linq的所有功能，因此您不必从头开始将方法编写为averageAccounts。

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