POST values not received in PHP when submitted with .NET WebClient class

I'm trying to send some POST data with the .NET WebClient class as following:

WebClient objWebClient = new WebClient();

NameValueCollection objNameValueCollection = new NameValueCollection();
objNameValueCollection.Add("variable1", value1);
objNameValueCollection.Add("variable2", value2);
objNameValueCollection.Add("variable3", value3);

byte[] bytes = objWebClient.UploadValues(objURI, "POST", objNameValueCollection);
MessageBox.Show(Encoding.ASCII.GetString(bytes));

But when I print the POST values in PHP with

var_dump($_POST)

I'll get an empty string.

What I'm doing wrong here? Why are the POST values obviously not submitted to the PHP script?

Thanks in advance for any ideas Andreas

I've found the solution myself now and just want to share the result.

It had nothing to do with my code itself. The problem was that I've added a redirect to my Apache configuration to redirect all requests from my domain www.ab-tools.de to www.ab-tools.com.

But the .NET application still posted the data to a script below the old domain.

As a redirect drops all POST data, the script did not get the data from the .NET application.

That was really a stupid mistake - it took me a while till I understood that. ;-)

Best regards and thanks again for all replies Andreas

There is nothing wrong on your code... tested it locally:

    static void Main(string[] args)
    {
        WebClient objWebClient = new WebClient();

        NameValueCollection objNameValueCollection = new NameValueCollection();
        objNameValueCollection.Add("variable1", "test");
        objNameValueCollection.Add("variable2", "ast");
        objNameValueCollection.Add("variable3", "ost");

        byte[] bytes = objWebClient.UploadValues("http://localhost/test.php", "POST", objNameValueCollection);
        Console.Write(Encoding.ASCII.GetString(bytes));
        Console.WriteLine();
        Console.WriteLine("Press any key to exit");
        Console.ReadLine();
    }

Test file:

<?php
    echo "Result:";
    print_r($_POST);
?>

Result: enter image description here
