Array.find（）提供奇怪的结果

我正在为我的兼职编程课程编写作业。我的代码的问题是array.find（）和该搜索的结果。它应该（按照我的理论）在数组中搜索信息，然后将其发布给用户，但是所有搜索的结果都是一样的：ass2task1.Program + customer这只是部分代码，因为老师告诉了我我们可以在互联网上发布问题，只要我们不发布整个代码即可

 struct customer
    {
        public int customernumber;
        public string customersurname;
        public string customerforname;
        public string customerstreet;
        public string customertown;
        public DateTime customerdob;
    }

    static void Main(string[] args)
    {
        customer[] customerdetails = new customer[99];
        int selector = 0;
        int selector2 = 0;
        string vtemp = "";
        string ctemp = "";
        int searchnumber;
        string searchforename;    //variable/ array declaring
        string searchsurname;
        string searchtown;
        DateTime searchdob;
        customer resultnumber;
        customer resultforename;
        customer resultsurname;
        customer resulttown;
        customer resultdob;


  if (selector2 == 2)
                    {
                        Console.Clear();
                        Console.WriteLine("Enter the forename you are looking for: ");
                        searchforename = (Console.ReadLine());
                        resultforename = Array.Find(customerdetails, customer => customer.customerforname == searchforename);
                        Console.Clear();
                        Console.WriteLine("Enter the surname you are looking for: "); // all of the searches comes out with ass2task1.Program+customer  result
                        searchsurname = (Console.ReadLine());
                        resultsurname = Array.Find(customerdetails, customer => customer.customersurname == searchsurname);
                        Console.WriteLine("The forename resuts:" + resultforename);
                        Console.WriteLine("The surname resuts:" + resultsurname);
