Aspx引擎

我有一个网络表单，要求用户输入用户ID。用户标识用于搜索类并显示与用户标识匹配的类。

现在出现的问题是，当我输入用户ID时，会显示所有类。只有类才会被显示出来。具有在文本框中输入的userId的类

HTML

<div align="center">
    <form id="searchUser" method="post" action="Search">

模型

  public class SearchClass
{
    public string userId { get; set; }
    public string email { get; set; }
    public string lastFourdigits { get; set; }

    public static List<AAlexUsers.Models.SearchClass>Users(string userId, string email, string lastFourdigits)   
    {
        SearchClass Alex = new SearchClass();
        Alex.userId = "1234";
        Alex.email = "Alex@gmail.com";
        Alex.lastFourdigits = "1885";

        SearchClass Emilio = new SearchClass();
        Emilio.userId = "0928";
        Emilio.email = "Cubano@gmail.com";
        Emilio.lastFourdigits = "0706";

        SearchClass Ulysses = new SearchClass();
        Ulysses.userId = "0914";
        Ulysses.email = "lysses@gmail.com";
        Ulysses.lastFourdigits = "01zx";

        var list = new List<SearchClass>();
        list.Add(Alex);
        list.Add(Emilio);
        list.Add(Ulysses);

        return list;

    }

我希望这能指出你正确的方向。

public class SearchClass
{
    public string userId { get; set; }
    public string email { get; set; }
    public string lastFourdigits { get; set; }

    public static List<SearchClass> Users(string userId, string email, string lastFourdigits)   
    {
        SearchClass Alex = new SearchClass();
        Alex.userId = "1234";
        Alex.email = "Alex@gmail.com";
        Alex.lastFourdigits = "1885";

        SearchClass Emilio = new SearchClass();
        Emilio.userId = "0928";
        Emilio.email = "Cubano@gmail.com";
        Emilio.lastFourdigits = "0706";

        SearchClass Ulysses = new SearchClass();
        Ulysses.userId = "0914";
        Ulysses.email = "lysses@gmail.com";
        Ulysses.lastFourdigits = "01zx";

        var list = new List<SearchClass>();
        list.Add(Alex);
        list.Add(Emilio);
        list.Add(Ulysses);

        IEnumerable<SearchClass> result = list;
        if(!string.IsNullOrEmpty(userId))
            result = result.Where(u => u.userId == userId);
        if(!string.IsNullOrEmpty(email))
            result = result.Where(u => u.email == email);
        if(!string.IsNullOrEmpty(lastFourdigits))
            result = result.Where(u => u.lastFourdigits == lastFourdigits);

        return result.ToList();
    }

在类中搜索并根据用户ID /文本框显示表中的类
