c# - 使用 post 将 C# 数组发送到 PHP Web 服务

Question

我正在尝试使用下面的代码将此数组 string[] str = { "abc", "sdfsdf"}; 值发送到 PHP(网络服务)，但它总是给我以下输出

在 PHP 文件中，我有以下代码实际接收数组并输出带有值的总结构:

<?php    
  $messages = $_POST['messages'];
  print_r($messages);
?>

问题可能是 PHP 无法读取我发送的数组；可能是因为我是从 C# 发送的。

能否请您告诉我如何正确发送数组，以便 PHP 网络服务可以读取它。

仅供引用:我无权编辑 Web 服务端的任何代码。

我的完整 C# 代码

string[] str = { "num" ,  "Hello World" };

string url = "http://localhost/a/cash.php";

HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create( url );

ASCIIEncoding encoding = new ASCIIEncoding();

string postData ;//= "keyword=moneky";
       postData = "&messages[]=" + str;

byte[] data = encoding.GetBytes(postData);

httpWReq.Method = "POST";
httpWReq.ContentType = "application/x-www-form-urlencoded";
httpWReq.ContentLength = data.Length;

  using (Stream stream = httpWReq.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }

HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();

string responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

MessageBox.Show(responseString);

经过反复试验，我终于找到了正确的解决方案。如果有人需要，这里是代码:

我不得不使用字典:

Dictionary<string, string> myarray =
    new Dictionary<string, string>();

    myarray .Add("0", "Number1");
    myarray .Add("1", "Hello World");

然后

string str = string.Join(Environment.NewLine, myarray); 

然后我剩下的代码:

string url = "http://localhost/a/cash.php";

HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create( url );

ASCIIEncoding encoding = new ASCIIEncoding();

 string postData = "keyword=moneky";
        postData += "&messages[]=" + str;

 byte[] data = encoding.GetBytes(postData);

 httpWReq.Method = "POST";
 httpWReq.ContentType = "application/x-www-form-urlencoded";
 httpWReq.ContentLength = data.Length;

 using (Stream stream = httpWReq.GetRequestStream())
    {
        stream.Write(data, 0, data.Length);
    }

HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();

string responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

MessageBox.Show(responseString);
