我是 C# 编程的初学者。请帮我将 PHP 中的代码示例重写为 C#：

<?php
  $final = array('header' => array(), 'data' => array());
  $final['header'] = array('title' => 'Test', 'num' => 5, 'limit' => 5);

  foreach ($results as $name => $data)
  {
    $final['data'][] = array('primary' =>'Primary','secondary' => 'Secondary','image' => 'test.png','onclick' => 'alert('You clicked on the Primary');');
  }

  header('Content-type: application/json');
  echo json_encode(array($final));
?>

我试图做这样的事情，但没有成功。

Dictionary<string, string> final = new Dictionary<string, string>();
stringArray.Add("header", "data");

“最简单”的方法是Dictionary<Object, Object>. 由于 PHP 的数据类型如此松散，因此 anObject会给您更大的灵活性。然后 .NET 会根据需要将值装箱。就像是：

/* $final */
IDictionary<Object, Object> final = new Dictionary<Object, Object>();

/* $final["header"] */
// by keeping this separated then joining it to final, you avoid having
// to cast it every time you need to reference it since it's being stored
// as an Object
IDictionary<Object, Object> header = new Dictionary<Object, Object> {
    { "title", "Test" },
    { "num", 5 },
    { "limit", 5 }
};
// above short-hand declaration is the same as doing:
// header.Add("title", "Test");
// header.Add("num", 5);
// header.Add("limit", 5);
final.Add("header", header);

/* $final["data"] */
IList<Object> data = new List<Object>();
// not sure where `results` comes from, but I'll assume it's another type of
// IDictionary<T1,T2>
foreach (KeyValuePair<Object, Object> kvp in results)
{
    data.Add(new Dictionary<Object, Object> {
        { "primary", "Primary" },
        { "secondary", "Secondary" },
        { "image", "test.png" },
        { "onclick", "alert('You clicked on the Primary');" }
    });
}
final.Add("data", data);

请记住，这肯定不是最优化的，但确实使它最接近您正在使用的内容。

从那里，您可以使用库（如Newtsonsoft Json）并序列化信息。

JsonConvert.SerializeObject(final);

测试和工作：

我将$results/results作为相等的值添加到两者（foo->Foo,bar->Bar,baz->Baz），然后将两者序列化为 JSON 并产生相同的结果：

[{"header":{"title":"Test","num":5,"limit":5},"data":[{"primary":"Primary","secondary":"Secondary", "image":"test.png","onclick":"alert('You clicked on Primary');"},{"primary":"Primary","secondary":"Secondary","image": "test.png","onclick":"alert('你点击了 Primary');"},{"primary":"Primary","secondary":"Secondary","image":"test.png ","onclick":"alert('你点击了主节点');"}]}]

与您所要求的略有不同，但我可能会做类似的事情：

class ReturnArg
{
    public Dictionary<Object, Object> header = new Dictionary<Object, Object>();
    public Dictionary<Object, Object> data = new Dictionary<Object, Object>();
}

然后（在 MVC 控制器中？）：

public JsonResult GetRevisions(int id)
{
    ReturnArg r = new ReturnArg();

    r.header.Add("title", "Test");
    r.header.Add("num", 5);
    r.header.Add("limit", 5);

    r.data.Add("primary", "Primary");
    ...

    return Json(r);
}

也可以：

var r = new
{
    header = new { title = "Test", num = 5, limit = 5 },
    data = new { primary = "Primary", secondary = "Secondary" }
};

希望有帮助。
