c# receive text file(s) located in documents directory, then send text file with API

Question

Hello (sorry for my bad English), so basically i'm creating a simple c# application that retrieves .txt files located within the documents directory. My program is going to allow users to open these text files and edit them, then upload to my website.

the text files i'm looking to retrieve are located in this path:

Libraries -> Documents -> XYZtxtMapper -> Savedstuff -> example.txt

I'm looking for some sort of way in c# to receive the example.txt file within the path shown above, once I've retrieved the example.txt file i would call a API on my server, example:

var client = new WebClient()) 
client.DownloadString("https://example.com/file=" + example.txt); //<- Calls my API

Once the above is called i would use PHP to $_GET['file'] , then what PHP code would i use to upload the txt file that i use $_GET['file'] to my server? Could i use fwrite() to upload the file to my server (website)?

Sorry for my bad English and me being a noob! I'm still pretty new to all this programming stuff

Your English make your explain not very well. As I understand, you want use a C# app to send a string to your server via GET method, then get it's response, right?

Then if you use WebClient:

WebClient wc = new WebClient();
string yourString = File.ReadAllText("C:\\path\\toYourFile.txt"); // Read file content
// string yourString = "C:\\path\\toYourFile.txt"; // Or you want send filename
string response = wc.DownloadString("https://example.com/pathTo/yourPHPFile.php?file=" + WebUtility.UrlEncode(yourString));

Note: You have to include pathto/yourPHPFile.php?file= to your URL, where pathto/yourPHPFile.php is your php file, ? is the begin your query. If you unfamily with this, read more about PHP GET
