C# is not my forte but here's a very basic example:
private void button1_Click(object sender, System.EventArgs e)
{
HttpWebRequest request = (HttpWebRequest)
WebRequest.Create("http://localhost/file.php");
request.Headers["Something"] = "Dingo";
HttpWebResponse response = (HttpWebResponse) request.GetResponse();
Stream hs = response.GetResponseStream();
FileStream fs = new FileStream("C:\\test.gif", FileMode.Create,
FileAccess.Write);
BinaryWriter bw = new BinaryWriter(fs);
BinaryReader br = new BinaryReader(hs);
Byte[] buffer;
do {
buffer = br.ReadBytes(1024);
bw.Write(buffer);
} while(buffer.Length > 0);
bw.Close();
br.Close();
}
The PHP script just dumps a gif file into the output:
<? readfile("dingo.gif"); ?>
I suggested using the HTTP headers to pass parameters in another post,
as it's fairly easy to set their values. In the PHP script, the
"Something" header will become $_SERVER['HTTP_SOMETHING']. The PHP
script can set response header using the header() function:
header("Dingo: Ate my wienerschnitzel!");
Which then is accessible through HttpWebResponse.Headers["Dingo"].
