public class Language_Codes{public int Id { get; set; }public string code { get; set; }public string Name { get; set; }}

public CodeEntity(): base("DefaultConnection"){}public DbSet<Language_Codes> Language_Code{get;set;}}

<connectionStrings><add name="DefaultConnection" connectionString="server=.;database=LanguageCode;uid=sa;pwd="providerName="System.Data.SqlClient" /></connectionStrings>

CodeEntity dbcontext = new CodeEntity();

 public ActionResult Index(){List<Language_Codes> list=  dbcontext.Language_Code.ToList();return View(list);}

@model IEnumerable<Translator.Models.Language_Codes>
@{ViewBag.Title = "Index";
}
<table  class ="table table-striped"><tr><td><label>要翻译的文本</label><textarea id="text" class="form-control"   rows="5"></textarea></td><td>将<select id="from" class="form-control"><option value="1">请选择</option>@foreach (var item in Model){<option id="@item.Id" value="@item.code">@item.Name</option>}</select>翻译成<select id="to" class="form-control"><option value="1">请选择</option></select><button id="submit" class="btn btn-default">翻译</button></td><td><label>翻译的文本</label><textarea id="transtext" class="form-control" rows="5"></textarea></td></tr></table>在layout.cshtml中添加

1   <div class="navbar-collapse collapse">
2                 <ul class="nav navbar-nav">
3                     <li>@Html.ActionLink("主页", "Index", "Home")</li>
4                     <li>@Html.ActionLink("关于", "About", "Home")</li>
5                     <li>@Html.ActionLink("联系方式", "Contact", "Home")</li>
6                     <li>@Html.ActionLink("翻译", "Index", "Translator")</li>
7                 </ul>
8             </div>

效果如下

五.利用AJAX动态加载数据

1.加载LanguageCode
首先在控制器中添加一个LoadLanguageCode来处理加载语言代码请求

 public ActionResult LoadLanguageCode(int id){List<Language_Codes> list = dbcontext.Language_Code.Where(c=>c.Id!=id).ToList();return Json(list);}

在Scripts文件夹添加一个translator.js文件，并在视图中添加此文件的引用<script src="~/Scripts/translator.js"></script>给第一个select注册一个事件，每次select中选项更改时我们去加载第二个select的选项document.getElementById("from").οnchange=function()    {        var selectedid = $(":selected","#from").attr("id");        $.ajax(            {                url: "../Translator/LoadLanguageCode",                type: "post",                data: { id: selectedid },                success: function (_JsonData)                {                    $('#to').empty();                    for (var i = 0; i < _JsonData.length; i++) {                        $('#to').append($('<option' + '  id=' + _JsonData[i].Id + '  value=' + _JsonData[i].code + '>' + _JsonData[i].Name + '</option>'));                    }                }            })    }2.向microsoft请求服务在TranslatorController添加 Translate方法

 [HttpPost]public ActionResult Translate(string from,string to,string text){AdmAuthentication adm = new AdmAuthentication("zuin", "Ursm3pji3Fcha+70plJFrAbHT/Y00F7vyKdXlWLusmc=");//string text = textBox1.Text;//string from = "zh-CHS";//"zh-CHS"//string to = "en";string uri = "http://api.microsofttranslator.com/v2/Http.svc/Translate?text=" + System.Web.HttpUtility.UrlEncode(text) + "&from=" + from + "&to=" + to;string authToken = "Bearer" + " " + adm.token.access_token;HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(uri);httpWebRequest.Headers.Add("Authorization", authToken);WebResponse response = null;try{response = httpWebRequest.GetResponse();using (Stream stream = response.GetResponseStream()){System.Runtime.Serialization.DataContractSerializer dcs = new System.Runtime.Serialization.DataContractSerializer(Type.GetType("System.String"));string translation = (string)dcs.ReadObject(stream);return Json(translation);}}catch{string code = "fail";return Json(code);}}给“翻译”按钮注册事件

  $('#submit').click( function (){var formvalue =$("#from").val();var tovalue = $("#to").val();var textvalue = $("#text").val();$.ajax({url: "../Translator/Translate",type: "post",data: {from: formvalue, to: tovalue, text:textvalue },success: function (_JsonData) {$('#transtext').empty();if (_JsonData=='fail') {alert("失败！,请联系管理员或使用微软必应在线翻译");}else {document.getElementById("transtext").innerHTML = _JsonData;}}})})
