在c中jquery使用哪个JSON模式#

我是JSON新手，以前从未在c#/.Net中使用过它

我正在尝试将JSON文件链接到MVC项目中的现有SQL。 我读了很多东西，在这个网站上搜索了所有的答案，但是还没有找到。 我不在学校，我所知道的关于Json和SQL的一切都是通过研究。我仍在自学，向任何人寻求帮助

我的最终目标是在Json文件中有一个

get

和

post

，。回电话

1） 我在模型中创建了一个Json文件，但不知道使用哪个模式。MVC给了我很多选择。理想情况下，我希望使用JQuery，我对它有点熟悉

2） 一旦我通过了这个阶段，我将如何让它链接到我的SQL，我使用ADO.Net创建了SQL，并将其命名为.edmx。（也许我不需要给它命名为.edmx，因为如果它有这个标识符，我看不出有什么区别）

请不要仅仅把我当作无关紧要的人，帮助新手进入这个令人兴奋的领域

我用MSMS得到了两张桌子，第三张桌子结合了这两张桌子。 我已经创建了一个空白控制器和一个空白视图。目前我仅有的代码是我在ADO中复制和执行的SQL。以下是SQL代码：

将数据从控制器传递到视图

@model DemoProject.Models.PersonViewModel

<h1>Person Details</h1>

<table>
    <tr>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Colour Name</th>
    </tr>
    @foreach(var person in Model)
    {
    <tr>
        <td>@person.FirstName</td>  
        <td>@person.LastName</td>  
        <td>@person.ColourName</td>  
    </tr>
    }
</table>

本节目介绍了如何将数据从控制器传递到视图，但要将

Json

数据从控制器传递到视图，我提供了以下参考

查看模型

public class PersonViewModel
{

  public int PersonId { get; set; }

  public string FirstName { get; set; }

  public string LastName { get; set; }

  public bool IsAuthorised { get; set; }

  public int ColourId { get; set; }

  public string ColourName { get; set; }

}

行动方法

 public ActionResult Index()
  {


// TODO, Get data from SQL database using ADO.NET or Entity Framework

Person personData = GetDataFromSQLServerRepository();

// Fill your view model

PersonViewModel model = new PersonViewModel();

model.FirstName  = personData.FirstName;
model.LastName   = personData.LastName ;
model.ColourName = personData.ColourName;

        return View(model);
 }

索引视图

@model DemoProject.Models.PersonViewModel

<h1>Person Details</h1>

<table>
    <tr>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Colour Name</th>
    </tr>
    @foreach(var person in Model)
    {
    <tr>
        <td>@person.FirstName</td>  
        <td>@person.LastName</td>  
        <td>@person.ColourName</td>  
    </tr>
    }
</table>

@model DemoProject.Models.PersonViewModel
人员详细信息
名字
姓
颜色名称
@foreach（模型中的var人员）
{
@人名
@person.LastName
@人名
}

        <td>@person.FirstName</td>  
        <td>@person.LastName</td>  
        <td>@person.ColourName</td>  
    </tr>
    }

-使用

下划线js

进行更好的模板制作。

您能更清楚地解释一下，显示一些您已经完成的代码，或者使用

c

和

Jquery

需要什么样的输出吗？我已经编辑了我的问题并包含了SQL代码OK，但您仍在尝试做什么？您希望将SQL Server数据库中的数据转换为

Json

格式，并使用

Jquery

显示在网页中，还是希望将

Json

数据保存到

SQL

表中？试着解释一下，以便其他人可以指导你。我的最终目的是，我试图通过Json访问数据，并以HTML格式复制它
