C＃HTTP POST和PHP

大家好，我有C＃代码将字符串发布到URL。
我希望在我的PHP脚本中获得该值。我试过这样的东西，但PHP没有回应！。我是C＃和PHP的新手。在这方面的任何帮助表示赞赏。

C＃Code
string test =" test = this is a test"; （我正在使用ContentType = application / x-www-form-urlencoded）


PHP代码
$ data = $ _POST [" test"];
echo $ data;

Hi all,
I have C# code that posts a string to an URL.
I would like to get that value in my PHP script. I tried to something like this but the PHP echoed nothing!.
I'm new to C# and PHP. Any help in this regard is appreciated.

C# Code
string test = "test=this is a test"; (I'm using ContentType = application/x-www-form-urlencoded)


PHP Code
$data = $_POST["test"];
echo $data;
