我正在使用 C# asp.net mvc4 并尝试进行 ajax 搜索。但是有错误，它说“找不到资源。”。我做错了什么？

控制器

    //Search
    [HttpPost]
    public ActionResult ContractSearch(string Name)
    {
        var contracts = db.Contracts.Include(c => c.DocType).Include(c => c.CreditType).Include(c =>          c.Bank).Include(c => c.UserProfile).Where(c => c.FirstName.Equals(Name));
        return View(contracts.ToList());
    }

看法

@model IEnumerable<CreditoriyaApp.Models.Contract>

@{
ViewBag.Title = "Index";
}

<div>
@using (Ajax.BeginForm("ContractSearch", "Contract", new AjaxOptions { UpdateTargetId = "searchresults" }))
{
<input type="text" name="Name" />
<input type="submit" value="Search" />
}

<div id="searchresults">
@if (Model != null && Model.Count()>0)
{
    <ul>
    @foreach (var item in Model)
    { 
        <li>@item.FirstName</li>
    }
    </ul>
}
</div>

错误

Server Error in '/' Application.

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed,   had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is  spelled correctly. 

Requested URL: /Contract/ContractSearch

在您的控制器中添加以下内容。然后你的错误将得到纠正。

public ActionResult ContractSearch()
{
   return View();
}

对于搜索，您可以尝试以下示例。

模型：

public class Person
    {
        public string Name { get; set; }
        public string Country { get; set; }

    }

控制器：

public ActionResult SearchPerson()
        {

            return View();
        }

        [HttpPost]
        public ActionResult SearchPerson(string searchString)
        {
            System.Collections.Generic.List<Person> lst = new List<Person>();
            lst.Add(new Person { Name = "chamara", Country = "Sri Lanka" });
            lst.Add(new Person { Name = "Arun", Country = "India" });
            if (!string.IsNullOrEmpty(searchString))
            {
                lst = lst.AsEnumerable().Where(r => r.Name.Contains(searchString)).ToList();
            }
            string result = string.Empty;
            result = "<p>Search Result<p>";
            foreach (Person item in lst)
            {
                result = result + "<p> Names is: " + item.Name + " and Country is:" + item.Country + "<p>";
            }
            return Content(result, "text/html");
        }

看法：

@model IEnumerable<Mvc4Test.Models.Person>

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>SearchPerson</title>
     <script src="@Url.Content("~/Scripts/jquery-1.7.1.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
</head>
<body>

@using (Ajax.BeginForm("SearchPerson", "Search", new AjaxOptions { HttpMethod = "Post", UpdateTargetId = "searchresults" }))
{
 @Html.TextBox("searchString")
<input type="submit" value="Search" />
}    

<div id="searchresults">

</div>
</body>
</html>
