从PHP数组转换为C＃字典 [英] Converting from PHP array to C# dictionary

问题描述

我在C＃编程初学者。请帮我在PHP这个code样品重新写C＃：

 ＆LT; PHP
  $最后=阵列（'标题'=＆GT;数组（），'数据'=＆GT;阵（））;
  $最后的['标题'] =阵列（'标题'=＆GT;'测试'，'民'=＆GT; 5，限价=大于5）;  的foreach（$结果$名=＆GT; $数据）
  {
    $最后的['数据'] [] =阵列（'初级'=＆GT;'主'，'二级'=＆GT;'二次'，'形象'=＆GT;'test.png'，'的onclick =＆GT; 警报（'你点击主'）;'）;
  }  标题（内容类型：应用程序/ JSON'）;
  回声json_en code（阵列（$最终））;
？＆GT;
 

我试图做这样的事情，但都没有成功。

 词典＆LT;字符串，字符串＆GT;最后=新词典＆LT;字符串，字符串＆GT;（）;
stringArray.Add（头，数据）;
 

解决方案

在最简单的方法将是词典＆LT;对象，对象＆gt; 。由于PHP是数据类型那么松，一个对象会给你更多的灵活性。然后将.NET值作为必要 框。是这样的：

  / * $决赛* /
IDictionary的＆LT;对象，对象＆gt;最后=新词典＆LT;对象，对象＆gt;（）;/ * $决赛[标题] * /
//通过保持这种分离然后将其加入到最后的，您就不必
//每一个需要引用它时施放它，因为它被存储
//为Object
IDictionary的＆LT;对象，对象＆gt;标题=新词典＆LT;对象，对象＆gt; {
    {称号，测试}，
    {NUM，5}，
    {限制，5}
};
//上述短手声明是一样的操作的方式：
// header.Add（称号，测试）;
// header.Add（民，5）;
// header.Add（限制，5）;
final.Add（头，头）;/ * $决赛[数据] * /
IList的＆LT;对象＆gt;数据=新的List＆LT;对象＆gt;（）;
//不知道在哪里`results`从何而来，但我会假设它是另一种类型的
// IDictionary的＆所述的T1，T2和GT;
的foreach（KeyValuePair＆LT;对象，对象＆gt; KVP的结果）
{
    data.Add（新字典＆LT;对象，对象＆gt; {
        {主，主}，
        {次要，次要}，
        {图像，test.png}，
        {的onclick，警报（'你点击主'）; }
    }）;
}
final.Add（数据，数据）;
 

只要记住，这是肯定的不可以最优化的，但确实使最接近你正在使用的东西。

从那里，你可以使用库（如 Newtsonsoft的Json ）和序列化的信息。

  JsonConvert.SerializeObject（最后一次）;

测试和工程：

• 您的PHP版本： http://ideone.com/NzfIj4


• C＃版本（上图）

我添加 $结果 / 结果来既作为相等值（foo->富，酒吧，>酒吧，baz->巴兹），那么序列既JSON和导致相同

  

[{\"header\":{\"title\":\"Test\",\"num\":5,\"limit\":5},\"data\":[{\"primary\":\"Primary\",\"secondary\":\"Secondary\",\"image\":\"test.png\",\"onclick\":\"alert('You点击主'）;}，{主：主，次要：中学，形象：test.png，onclick事件：警报（'你点击主'）;}，{主：主，次要：中学，形象：test.png，onclick事件：警报（'你点击主'）; }]}]

I am a beginner in C# programing. Please help me re-write this code sample in PHP to 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));
?>

I have tried to do something like this, but have had no success.

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

解决方案

The "easiest" method would be a Dictionary<Object, Object>. Since PHP is so loose with data types, an Object would give you more flexibility. Then .NET would box the value as necessary. Something like:

/* $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);

Just keep in mind, this is certainly not the most optimized, but does make it closest to what you're working with.

From there, you can use a library (like Newtsonsoft Json) and serialize the information.

JsonConvert.SerializeObject(final);

Tested and works:

• Your PHP Version: http://ideone.com/NzfIj4
• The C# Version (above)

I added $results/results to both as equal values (foo->Foo,bar->Bar,baz->Baz) then serialized both to JSON and result in the same:

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