POSaving a file that has been opened by a particular process in C#

Body
copied!<p>I'm working with a filetype that doesn't exist in the public domain. The file is in binary or hex, but there's been a previous batch file written that runs when you double click on a file in order to open it as a .txt file in notepad. </p> <p>What I am trying to do is to open this file within my program, and then save it while it is open so that it is now a .txt file, and I can work with it.</p> <p>So I start the batch file process and the file itself is the argument.</p> <pre><code>/*Start the batch file and open file (as an argument) * Then it'll be viewable as a text file * */ Process process = new Process(); process.StartInfo.FileName = "C:/batchfile.bat"; process.StartInfo.Arguments = "C:/file.ext"; process.StartInfo.UseShellExecute = false; process.StartInfo.RedirectStandardOutput = true; process.Start(); </code></pre> <p>I then look to see if any of the current running processes have the file extension and are running in notepad, using Regex:</p> <pre><code>/*Using a regex pattern, we can see if a wtd file has been opened * If there is, it's added to an array called matchArr * */ String pattern = "^.*ext.*Notepad.*$"; Regex rgx = new Regex(pattern, RegexOptions.IgnoreCase); Process[] processes = Process.GetProcesses(); int useMatch = 0; String[] matchArr = new String[100]; foreach (var proc in processes) { MatchCollection matches = rgx.Matches(proc.MainWindowTitle); if (!string.IsNullOrEmpty(proc.MainWindowTitle)) if (matches.Count > 0) { useMatch = matches.Count; for (int i = 0; i < useMatch; i++) { matchArr[i] = proc.MainWindowTitle; String blah = proc.Modules[0].FileName; string path = System.IO.Path.GetFullPath(proc.MainWindowTitle); Console.WriteLine("Path:" +path); StreamReader stream = new StreamReader(blah); FileStream fstr = new FileStream("C:/newName.txt", FileMode.Create, FileAccess.Write); using (StreamWriter strw = new StreamWriter(fstr)) { strw.WriteLine(stream); Console.WriteLine("Array is : " + matchArr[i].ToString()); } } } } </code></pre> <p>I've been Googling all day - I must be going wrong somewhere in my approach, but I didn't think it should be so difficult to figure this out. Any help would be much appreciated - I'm not native to C# either, so excuse any bad coding practices. </p> <p>Can anybody help me to figure out how to change this file to a .txt file? Also, C# obviously doesn't read it as .txt so I can't just change the file extension as in Notepad, which is why I'm trying to do it this way. I also spent a lot of time messing around with encoding but to no avail.</p>
