Question

今天我一直在四处看看如何将我创建的这个字符串列表显示给名为“results”的操作结果。我想知道是否有人知道如何在.aspx页面上显示它？

public class Testimonials   
{
    public string AddTestimonials { get; set; }
    public string SearchTestimonials { get; set; }

    public List<string> results = new List<string>();

    public void getSearchResults(string keyword)
    {
        string query = "SELECT content from Testimonial where Content like '%@p1%';"; //insert statement
        SqlConnection db = new SqlConnection(@"");
        SqlCommand command = new SqlCommand(query, db);
        command.Parameters.AddWithValue("@p1", keyword);      // seting @p1 to the content
        db.Open();
        SqlDataReader reader = command.ExecuteReader();
        DataTable results = new DataTable();
        results.Load(reader); //Loads remaining surgeon credentials into a data table.
        foreach (DataRow row in results.Rows)
        {
            string cont = row["content"].ToString();
            this.results.Add(cont);
        }
        db.Close();
    }
}



    public ActionResult Testimonials()
    {
        return View();
    }
    [HttpPost]
    [Authorize]
    public ActionResult Testimonials(Testimonials model, string returnUrl)
    {
        if (model.AddTestimonials != null)
        {
            string query = "Insert Testimonial (content,date,surgeonID) VALUES (@p1,CURRENT_TIMESTAMP,@p2);"; //insert statement
            SqlConnection db = new SqlConnection(@"");
            SqlCommand command = new SqlCommand(query, db);
            command.Parameters.AddWithValue("@p1", model.AddTestimonials);      // seting @p1 to the content
            command.Parameters.AddWithValue("@p2", Convert.ToString(Session["surgeonID"]));
            db.Open();
            command.ExecuteNonQuery();
            db.Close();
            return RedirectToAction("Testimonials");
        }
        if (model.SearchTestimonials != null)
        {
            model.getSearchResults(model.SearchTestimonials);
            return RedirectToAction("Testimonials");
        }

        return View();
    }

我在许多不同的版本中尝试过“for every var”但没有成功。到目前为止这是aspx：

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared    /Site.Master"Inherits="System.Web.Mvc.ViewPage<TEAM3OIE2S.Models.Testimonials    >"%>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent"     runat="server">
    Testimonials
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent"     runat="server">
   <form id="form1" runat="server">

    <h2>Testimonials</h2>
<% using (Html.BeginForm()) { %>
<%: Html.TextBoxFor(m => m.AddTestimonials)%>
   <input type="submit" value="Add" />
<% } %>

<% using (Html.BeginForm()) { %>
 <%: Html.TextBoxFor(m => m.SearchTestimonials)%>
 <input type="submit" value="Search" />


<% } %>

</form>
</asp:Content>

在代码中进行这些更改。

public List<string> getSearchResults(string keyword)
{
    public List<string> results = new List<string>();
    //....
    foreach (DataRow row in results.Rows)
    {
        string cont = row["content"].ToString();
        this.results.Add(cont);
    }
    db.Close();
    return results;
}

现在在控制器内

var results = new Testimonials().getSearchResults("blah");
return View("Testimonials", results);

现在在View

@model List<string>
@foreach (var result in Model)
{
    <p>@Html.DisplayFor(m => result)</p>
}

在ASP.Net MVC中，您需要通过＆＃34; model＆＃34;到＆＃34;查看＆＃34;这样您就可以从视图中访问信息。通常由具有模型参数的Controller.View方法之一完成。

我不清楚你实际上想要展示什么，但是下面应该让你开始：
