C# PHP Communication ( Get / Send Data from C# to PHP )
This Piece of code will allow you, to Get information from Web page or Send Information to it, By Using POST method trough C# to a PHP Page.
C#🠖 Send Data 🠖 PHP Page 🠖 Processing Data 🠖 C# Get Information.
Let Show you the code:
Programm.cs
using System;
class Program
{
static void Main(string[] args)
{
string Data = Web.GetPost("http://www.smart-arab.com/example.php", "UserName", "Me", "Password", "123");
Console.WriteLine(Data);
}
}
Take a look at this line of code
Web.GetPost("www.smart-arab.com/example.php", "UserName", "Me", "Password", "123");
it’s said like this
1-“WebSite URL”.
2-“Post Variable” , 3-“It’s Value” , 4-“Post Variable” , 5-“It’s Value”
The Post Variable Must be identical inside C# and PHP code.
For Example :
“UserName” in c# code match “Post Variable” in PHP code $_POST[‘UserName’]
(those must be changed together)
And The User Name Value which in our case is “Me” , could be anything “Admin” , “Sarah” … etc, This value will be send from C# to PHP.
Again “Password” in c# code match “Post Variable” in PHP code $_POST[‘Password’]
(those must be changed together)
And Again The Password Value which in our case “123” could be any thing “1904” , “SuperPass” , etc … This value will be send from C# to PHP.
if you need more explain please let me know …
PHP Code:
example.php
<?PHP
if (isset($_POST['UserName'])) {
$UserName = $_POST['UserName'];
} else {
$UserName = null;
}
if (isset($_POST['Password'])) {
$Password = $_POST['Password'];
} else {
$Password = null;
}
echo $UserName . " Is And Password Is " . $Password
?>
C# Class : ( You don’t need to go through it deeply, just add it to your Project as a Class file )
Web.cs
using System;
using System.IO;
using System.Net;
using System.Text;
using System.Windows.Forms;
class Web
{
public static string GetPost(string Url, params string[] postdata)
{
string result = string.Empty;
string data = string.Empty;
System.Text.ASCIIEncoding ascii = new ASCIIEncoding();
if (postdata.Length % 2 != 0)
{
MessageBox.Show("Parameters must be even , \"user\" , \"value\" , ... etc", Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error);
return string.Empty;
}
for (int i = 0; i < postdata.Length; i += 2)
{
data += string.Format("&{0}={1}", postdata[i], postdata[i + 1]);
}
data = data.Remove(0, 1);
byte[] bytesarr = ascii.GetBytes(data);
try
{
WebRequest request = WebRequest.Create(Url);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = bytesarr.Length;
System.IO.Stream streamwriter = request.GetRequestStream();
streamwriter.Write(bytesarr, 0, bytesarr.Length);
streamwriter.Close();
WebResponse response = request.GetResponse();
streamwriter = response.GetResponseStream();
System.IO.StreamReader streamread = new System.IO.StreamReader(streamwriter);
result = streamread.ReadToEnd();
streamread.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error);
}
return result;
}
}
I’m not going to spoon feed this old post but I figured I should maybe just help out a bit for those that are still trying to figure a way to send more than one type of data back to C#. Basically php and C# can not directly send data back and forth from a website to an application. The best approach for this is to use JSON. I would suggest reading up on PHP/JSON and C#/JSON … Taken from Wiki “JavaScript Object Notation, is an open standard format that uses human-readable text to transmit data objects consisting of attribute–value pairs.” Using JSON will help you send multiple values in string based format that you can deserialize into a C# class.
Example: PHP JSON
echo"
{
'name' : 'ben',
'age' : 22
}
";
C# code will receive that as a string type which you can then deserialzie into a class.
Example: C# Class
public class UserData
{
public string Name { get; set; }
public int Age { get; set; }
}
