Problem with space in path, arguments C# to launch python script

I don't know how can I code the string format to keep the full path with space, because, it is split at each space.
4 arguments:
C:/MyDoc/Example/MyCSV File 1.csv
-1
20-05-2019
7
python.run_cmd("C:/MyCode.py", "C:/MyDoc/Example/MyCSV File 1.csv -1 20-05-2019 7");
Function:
public static void run_cmd(string cmd, string args)
{
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = "C:/PRGM/python.exe";
start.Arguments = string.Format("{0} {1}",cmd, args);
start.UseShellExecute = false;
start.RedirectStandardOutput = true;
using (Process process = Process.Start(start))
{
using (StreamReader reader = process.StandardOutput)
{
string result = reader.ReadToEnd();
Console.Write(result);
}
}
}

How about wrapping the file name in quotes, you'll need to escape them using a backslash \:
python.run_cmd("C:/MyCode.py", "\"C:/MyDoc/Example/MyCSV File 1.csv\" -1 20-05-2019 7");
or using a verbatim string:
python.run_cmd("C:/MyCode.py", #"""C:/MyDoc/Example/MyCSV File 1.csv"" -1 20-05-2019 7");

Pass arabic parameter to python script from c#

I want to pass Arabic string to python script from c#.
And then I will write output to txt file. But my arabic string parameter couldn't pass correctly. It transforms to "????" question marks.
I tried some code, like unicode, but it doesn't work
if __name__ == '__main__':
my_input = sys.argv[1]
out = open("C:\\output.txt", "wb")
p = unicode(my_input, encoding='utf-8')
out.write(p)
out.close()
Also my c# code is like that
public static string run_cmd(string args)
{
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = "C:/Python27/python.exe";
start.Arguments = "C:/test.py" + " " + args;
start.UseShellExecute = false;
start.RedirectStandardOutput = true;
using (Process process = Process.Start(start))
{
using (StreamReader reader = process.StandardOutput)
{
result = reader.ReadToEnd();
}
}
}
Do you have any idea how can I fix this problem?
Or is there something that I missing?
Any idea will be great!

Trying to run same command in command prompt not working

I am making a program that seeks out secured PDFs in a folder and converting them to PNG files using ImageMagick. Below is my code.
string WorkDir = #"C:\Users\rwong\Desktop\TestFiles";
Directory.SetCurrentDirectory(WorkDir);
String[] SubWorkDir = Directory.GetDirectories(WorkDir);
foreach (string subdir in SubWorkDir)
{
string[] filelist = Directory.GetFiles(subdir);
for(int f = 0; f < filelist.Length; f++)
{
if (filelist[f].ToLower().EndsWith(".pdf") || filelist[f].EndsWith(".PDF"))
{
PDFReader reader = new Pdfreader(filelist[f]);
bool PDFCheck = reader.IsOpenedWithFullPermissions;
reader.CLose();
if(PDFCheck)
{
//do nothing
}
else
{
string PNGPath = Path.ChangeExtension(filelistf], ".png");
string PDFfile = '"' + filelist[f] + '"';
string PNGfile = '"' + PNGPath + '"';
string arguments = string.Format("{0} {1}", PDFfile, PNGfile);
ProcessStartInfo startInfo = new ProcessStartInfo(#"C:\Program Files\ImageMagick-6.9.2-Q16\convert.exe");
startInfo.Arguments = arguments;
Process.Start(startInfo);
}
}
}
I have ran the raw command in command prompt and it worked so the command isn't the issue. Sample command below
"C:\Program Files\ImageMagick-6.9.2-Q16\convert.exe" "C:\Users\rwong\Desktop\TestFiles\Test_File File_10.PDF" "C:\Users\rwong\Desktop\TestFiles\Test_File File_10.png"
I looked around SO and there has been hints that spaces in my variable can cause an issue, but most of those threads talk about hardcoding the argument names and they only talk about 1 argument. I thought adding double quotes to each variable would solve the issue but it didn't. I also read that using ProcessStartInfo would have helped but again, no dice. I'm going to guess it is the way I formatted the 2 arguments and how I call the command, or I am using ProcessStartInto wrong. Any thoughts?
EDIT: Based on the comments below I did the extra testing testing by waiting for the command window to exit and I found the following error.
Side note: I wouldn't want to use GhostScript just yet because I feel like I am really close to an answer using ImageMagick.

Solution:
string PNGPath = Path.ChangeExtension(Loan_list[f], ".png");
string PDFfile = PNGPath.Replace("png", "pdf");
string PNGfile = PNGPath;
Process process = new Process();
process.StartInfo.FileName = #"C:\Program Files\ImageMagick-6.9.2 Q16\convert.exe";
process.StartInfo.Arguments = "\"" + PDFfile + "\"" +" \"" + PNGPath +"\""; // Note the /c command (*)
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.Start();
//* Read the output (or the error)
string output = process.StandardOutput.ReadToEnd();
Console.WriteLine(output);
string err = process.StandardError.ReadToEnd();
Console.WriteLine(err);
process.WaitForExit();
It didn't like the way I was formatting the argument string.

This would help you to run you command in c# and also you can get the result of the Console in your C#.
string WorkDir = #"C:\Users\rwong\Desktop\TestFiles";
Directory.SetCurrentDirectory(WorkDir);
String[] SubWorkDir = Directory.GetDirectories(WorkDir);
foreach (string subdir in SubWorkDir)
{
string[] filelist = Directory.GetFiles(subdir);
for(int f = 0; f < filelist.Length; f++)
{
if (filelist[f].ToLower().EndsWith(".pdf") || filelist[f].EndsWith(".PDF"))
{
PDFReader reader = new Pdfreader(filelist[f]);
bool PDFCheck = reader.IsOpenedWithFullPermissions;
reader.CLose()l
if(!PDFCheck)
{
string PNGPath = Path.ChangeExtension(filelistf], ".png");
string PDFfile = '"' + filelist[f] + '"';
string PNGfile = '"' + PNGPath + '"';
string arguments = string.Format("{0} {1}", PDFfile, PNGfile);
Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.EnableRaisingEvents = true;
p.StartInfo.CreateNoWindow = true;
p.startInfo.FileName = "C:\Program Files\ImageMagick-6.9.2-Q16\convert.exe";
p.startInfo.Arguments = arguments;
p.OutputDataReceived += new DataReceivedEventHandler(Process_OutputDataReceived);
//You can receive the output provided by the Command prompt in Process_OutputDataReceived
p.Start();
}
}
}
private void Process_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
if (e.Data != null)
{
string s = e.Data.ToString();
s = s.Replace("\0", string.Empty);
//Show s
Console.WriteLine(s);
}
}

Wrapper build errors when attempting to compile code

Ok so I completely re-wrote the code for this in an attempt to make this simpler. Now it is telling me that "Type or namespace definition, or end-of-file expected. I can only think my spacing is off or i'm missing a bracket, but when i try to add a bracket i get the same error. All I want to do is create simple wrapper for my EXE and its been very frustrating. Please if possible look at my code and tell me what i am doing wrong here. Any help is welcomed...
using System.IO;
//using Resources.resx;
namespace EXE_program
{
public class LaunchEXE
{
static void Main(string[] args)
{
string exeName = Path.Combine(Directory.GetCurrentDirectory(), "EntUpdate_v3.0.exe");
string argsLin = "";
int timeoutSeconds = 100;}
internal static string Run(string exeName, string argsLine, int timeoutSeconds)
{
StreamReader outputStream = StreamReader.Null;
string output = "";
bool success = false;
Process newProcess = new Process();
newProcess.StartInfo.FileName = exeName;
newProcess.StartInfo.Arguments = argsLine;
newProcess.StartInfo.UseShellExecute = false;
newProcess.StartInfo.CreateNoWindow = true; //The command line is supressed to keep the process in the background
newProcess.StartInfo.RedirectStandardOutput = true;
newProcess.Start();
return "\t" + output; }
}
}
}

How to repeatedly pass inputs and outputs between a C# Stream and a Python Script?

I'm trying to run a Python script from C# as a stream, and to repeatedly pass inputs and outputs between Python and the stream, using StreamWriter and StreamReader.
I can read and write, but apparently only once, and not multiple times. (Which is what I need.)
Hopefully, somebody can tell me what I'm doing wrong.
(I'm aware that I can probably do what I need to do by reading and writing to a file. However, I'd like to avoid this if I can, since using the Stream seems cleaner.)
Here's my C# code:
using System;
using System.Diagnostics;
using System.IO;
public class Stream_Read_Write
{
public static void Main()
{
string path = "C:\\Users\\thomas\\Documents\\Python_Scripts\\io_test.py";
string iter = "3";
string input = "Hello!";
stream_read_write(path, iter, input);
//Keep Console Open for Debug
Console.Write("end");
Console.ReadKey();
}
private static void stream_read_write(string path, string iter, string input)
{
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = "C:\\Python27\\python.exe";
start.Arguments = string.Format("{0} {1}", path, iter);
start.UseShellExecute = false;
start.RedirectStandardOutput = true;
start.RedirectStandardInput = true;
start.CreateNoWindow = true;
using (Process process = Process.Start(start))
using (StreamWriter writer = process.StandardInput)
using (StreamReader reader = process.StandardOutput)
{
for (int i = 0; i < Convert.ToInt32(iter); i++)
{
Console.WriteLine("writing...");
writer.WriteLine(input);
writer.Flush();
Console.WriteLine("written: " + input + "\n");
Console.WriteLine("reading...");
string result = reader.ReadLine();
Console.WriteLine("read: " + result + "\n");
}
}
}
}
The Python code looks like this:
import sys
iter = int(sys.argv[1])
for i in range(iter):
input = raw_input()
print (input)
And this is the output that I get:
writing...
written: Hello!
reading...
Strangely, when I remove the loops from both Python and C#, it works.
(For one iteration)
writing...
written: Hello!
reading...
read: Hello!
end
It's not clear to me why this happens, or what the solution could be, so any help is much appreciated.

I found a solution to my problem. I'm not really sure why this works, though.
For C#:
using System;
using System.Diagnostics;
using System.IO;
public class Stream_Read_Write
{
public static void Main()
{
string path = "C:\\Users\\thomas_wortmann\\Documents\\Python_Scripts\\io_test.py";
string iter = "3";
string input = "Hello";
stream_read_write(path, iter, input);
//Keep Console Open for Debug
Console.Write("end");
Console.ReadKey();
}
private static void stream_read_write(string path, string iter, string input)
{
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = "C:\\Python27\\python.exe";
start.Arguments = string.Format("{0} {1}", path, iter);
start.UseShellExecute = false;
start.RedirectStandardOutput = true;
start.RedirectStandardInput = true;
start.CreateNoWindow = true;
using (Process process = Process.Start(start))
using (StreamWriter writer = process.StandardInput)
using (StreamReader reader = process.StandardOutput)
{
for (int i = 0; i < Convert.ToInt32(iter); i++)
{
writer.WriteLine(input + i);
Console.WriteLine("written: " + input + i);
string result = null;
while (result == null || result.Length == 0)
{ result = reader.ReadLine(); }
Console.WriteLine("read: " + result + "\n");
}
}
}
}
And the python code looks like this:
import sys
def reverse(input):
return input [::-1]
iter = int(sys.argv[1])
for i in range(iter):
input = sys.stdin.readline()
print reverse(input)
sys.stdout.flush()

This is a conventional stream problem.
You have to “flush” the stream
(e.g. stdout.flush() , where stdout is a stream object)
in order to send the data
no matter in C# or in Python.
In C#, as I know, you have to execute stream.Close()
to complete the flush itself,
or you can wrap the stream with “using”
and it send the data when the brackets is closed.
Edit:
Btw, the stream is only available to one side at a time.
