Question

Within c#, i can put data to seperate strings.
For example the current date i put to a string called line1 and some info i put to a string called line2.

What i want to do now, is sent these 2 strings to a web adress that handles these lines, and write them into a simple text file. (or can i write to a text file on a website directly from C# ?)

My knowlage of php is very low, but so far i found this code to be working:

<?php 
 $File = "name.txt"; 
 $Handle = fopen($File, 'a');
 $Data = "line1\n"; 
 fwrite($Handle, $Data); 
 $Data = "line2\n"; 
 fwrite($Handle, $Data); 
 print "Data Added"; 
 fclose($Handle); 
 ?>

The C# application is running on a computer, not the website (WPF window).
But now it only has the content of the $Data written to the “name.txt” file.
Does anyone know how i could link the text that is binded to the stings in C3, to the datafields defined in the PHP, so that the text from the strings gets written to the text file on the website? Or would it be possible to write directly to a text file without the php in between ?

Answer 1

So, you have a C# app that you want to use to send 2 bits of data to a PHP based website, and have the website write the data into a file? If that’s what you want, you’ll need to do something like the following…

On the website, create a receiving PHP file. The bones of it would be something like :

<?php 
$File = "name.txt"; 
$Handle = fopen($File, 'a');
$line1 = $_GET["line1"] . "\n"; 
fwrite($Handle, $line1); 
$line2 = $_GET["line2"]; 
fwrite($Handle, $line2); 
print "Data Added"; 
fclose($Handle); 
echo "Completed writing data to the file";
?>

and to submit that data from the C# app to the website, do something as simple as

WebClient wc = new WebClient();
Console.WriteLine(wc.DownloadString("http://example.com/Receiver.php?line1=this is the first line&line2=and this is the second"));

(
NOTE : No error handling is included in this code, and anyone who knows the URL for the receiver will be able to overwrite your file with whatever they like. Take care when actually implementing this.
ALSO NOTE : It is years since I did much with PHP, so you will probably need to tweak the code.
AND ANOTHER THING : the WebClient.DownloadString approach is as basic as it gets. You may want to look at HttpWebRequests if you need more control
