I want to write an app. It called launch.exe. I want to write a method for check version with that app. Description : when I open that launch.exe , It will check the version from the Version file in current location of that launch. It will compare the version file from ftp server with the version file I had in that current location like I said. If you guys have any code or document about that please help me. Thanks alot!

Can you help me a bit more. I want to save the file I have downloaded to current drive. I don't want to save file like the code below

File.WriteAllText("D:\\55_SEPA_30-04-2017.xml", strXMLGenerate); --- not like that

Like I put my app in a folder in D drive, and then , I want to save files right that folder. How can I do that with code. Do you have any tips for me to do that?

firstly,
add this using System.IO; at the top .
then call some built-in functions like
Directory.Exists,
Directory.CreateDirectory...
And then the

HERE'S SOME CODE
PHP: 
string root = @"D:\Temp";  <--- the folder name
if (!Directory.Exists(root)) {Directory.CreateDirectory(root);  }
//else if Exists saves the files of you're app on that directory.
File.WriteAllText(root + "\\"+Filename+".xml", strXMLGenerate);
