Question

I’m trying to convert the following code snippet from PHP to C# or VB.NET This is from a PHP page which is used to catch a JSON string from an external webhook.

// Get the POST body from the Webhook and log it to a file for backup purposes...
$request_body = file_get_contents('php://input');
$myFile = "testfile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $request_body);
fclose($fh);

// Get the values we're looking for from the webhook
$arr = json_decode($request_body);
foreach ($arr as $key => $value) {
    if ($key == 'properties') {
        foreach ($value as $k => $v) {
            foreach ($v as $label => $realval) {
                if ($label == 'value' && $k == 'zip') {
                    $Zip = $realval;                    
                }
                elseif($label == 'value' && $k == 'firstname') {
                    $Fname = $realval;
                }
                elseif($label == 'value' && $k == 'lastname') {
                    $Lname = $realval;
                }
                elseif($label == 'value' && $k == 'email') {
                    $Email = $realval;
                }
                elseif($label == 'value' && $k == 'phone') {
                    $Phone = $realval;
                    $Phone = str_replace("(", "", $Phone);
                    $Phone = str_replace(")", "", $Phone);
                    $Phone = str_replace("-", "", $Phone);
                    $Phone = str_replace(" ", "", $Phone);
                }
                //need the other values as well!
            }
        }
    }
}

ETA: I’ve got the json string from the stream now. Still trying to figure out how to parse this. The JSON string format is out of my control, but I essentially need to get the “properties” node.

This answer would point you in the right direction on how to write a stream to a file. The stream in your case being Request.InputStream which is the equivalent of php://input.

To handle the JSON part look at @YYY’s answer.
