Open File from PowerShell via c#

In PowerShell this command: Invoke-Item D:\myFile.txt will open the file named myFile.
I'm tryind to run this PowerShell command From C#
I tried:
NuGet: System.Management.Automation
using (PowerShell PowerShellInstance = PowerShell.Create())
{
PowerShellInstance.AddScript("Invoke-Item D:\tx.txt");
PowerShellInstance.Invoke();
}
But this not opens the file

You can use this code:
Process process = new Process();
string scriptPath = $"YourPowershellCommand.ps1";
ProcessStartInfo startInfo = new ProcessStartInfo
{
FileName = scriptPath,
RedirectStandardError = true;
RedirectStandardOutput = true;
CreateNoWindow = true;
UseShellExecute = false
};
process.StartInfo = startInfo;
process.Start();
var stderrx = process.StandardError.ReadToEnd();
var stdout = process.StandardOutput.ReadToEnd();
process.WaitForExit();
Just save your powershell command in a ps1 file and give the path as a parameter. The code is not tested but it should work. Also C# process is in System.Diagnostics namespace.

How to run a command tool exe in C# web application?

I am using graphicmagic exe to execute a command using command prompt. I have added the graphicmagic exe in my application root folder. I want to execute this exe and pass the arguments through c#. How to do this? I have tried the below code:
Method: 1
Process proc = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = AppDomain.CurrentDomain.BaseDirectory + "\\gm1.3.5\\gm",
Arguments = "convert -define dpx:colorspace=rgb -define tiff:bits-per-sample=16 'D:\\Image\\FFv1\\dpx1\\1.dpx' 'D:\\Image\\FFv1\\tiff1\\1.tiff'",
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = true
}
}
Method: 2
Process proc = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = #"D:\Executable\Projects\MMF\gm1.3.5\gm";
startInfo.Arguments = "convert -define dpx:colorspace=rgb -define tiff:bits-per-sample=16 \"D:\\Image\\FFv1\\dpx1\\1.dpx\" \"D:\\Image\\FFv1\\tiff1\\1.tiff\"";
proc.StartInfo = startInfo;
proc.Start();
But both of its not working. Please suggest a way to execute exe file and pass commands.

It should be the privilege issue.
Try to adjust the identity in your app pool to LocalSystem.

This one is working fine:
using System.Diagnostics;
Process p = new Process();
p.StartInfo.FileName = #"D:\Executable\Projects\MMF\gm1.3.5\gm.exe";
p.StartInfo.Arguments = "convert -define dpx:colorspace=rgb -define tiff:bits-per-sample=16 \"C:\\Documents and Settings\\software\\Desktop\\DPX_Test\\3.dpx\" \"C:\\TEMP_21May2015103216\\3.tiff\"";
p.Start();
p.WaitForExit();

getting a blank cmd window by running command line from C#

I am trying to open command line in the c folder, from C#.
the expectation is to see this in the command line window:
C:>
but instead i am getting a blank cmd window.
this is the code:
var startInfo = new System.Diagnostics.ProcessStartInfo
{
WorkingDirectory = #"c:\",
WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal,
FileName = "cmd.exe",
RedirectStandardInput = true,
UseShellExecute = false
};
Console.ReadKey();

WaitForExit is what you are looking for.
EDIT:
var startInfo = new System.Diagnostics.ProcessStartInfo
{
WorkingDirectory = #"c:\",
WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal,
FileName = "cmd.exe",
RedirectStandardInput = true,
UseShellExecute = false
};
Process p = new Process();
p.StartInfo = startInfo;
p.Start();
p.WaitForExit();
This will halt the execution of all statements after WaitForExit. The time you close the command window, the statements following WaitForExit will be executed.

i think you're looking for this
first we'll create a process for CMD.exe and then passes "/K cd \". "/K" will "CMD.exe" to receive parameter and stay open, while "cd \" will take us to "C:/" which is your requirement
System.Diagnostics.Process.Start("CMD.exe", "/K \"cd /\"");
Console.ReadKey();

I believe if you use the /K Argument when executing the command, you should have a command prompt running at C:\
ProcessStartInfo startinfo = new ProcessStartInfo();
startinfo.FileName = "cmd.exe";
startinfo.WorkingDirectory = #"C:\";
startinfo.Arguments = "/K";
startinfo.UseShellExecute = false;
Process.Start(startinfo);
Or
Process command = new Process();
command.StartInfo.UseShellExecute = false;
command.StartInfo.WorkingDirectory = #"C:\";
command.StartInfo.Arguments = "/K";
command.StartInfo.FileName = "cmd.exe";
command.Start();
The /K argument executes the cmd.exe command and keeps the window open :)

how to run a python code using cmd.exe from a C# application?

I have an application where i am trying to run a python from a c# application. i have tried creating the python runtime environment and run the code, but as my python code is importing some modules from another python file it throws an exception (import exception). i have tried the following code:
var ipy = Python.CreateRuntime();
dynamic test = ipy.UseFile(#"file path");
test.Simple();
Console.Read();
I hvae another idea of running it through cmd prompt, but i don't know how do it. i want open to cmd.exe and execute the python file and i want it such that the user enters the filename in c# aplication and on clicking the run button the code is executed through cmd.exe and the output is again shown in c# application.
Any other suggestions are also welcome.

That would do the job: the following example runs cmd which runs TCL script (that wat I have installed on my computer) you only need to replace the command to run Python and add your script file.
Pay attention to the " & exit" comming after your script file name - this makes the cmd exit after your script exits.
string fileName = "C:\\Tcl\\example\\hello.tcl";
Process p = new Process();
p.StartInfo = new ProcessStartInfo("cmd", "/K tclsh " + fileName + " & exit")
{
RedirectStandardOutput = true,
UseShellExecute = false,
CreateNoWindow = true
};
p.Start();
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();
Console.WriteLine(output);
Console.ReadLine();
[Update]
After Python installation and testing, that would be the code to run python script with cmd:
string fileName = #"C:\Python27\example\hello_world.py";
Process p = new Process();
p.StartInfo = new ProcessStartInfo("cmd", "/K " + fileName + " & exit")
{
RedirectStandardOutput = true,
UseShellExecute = false,
CreateNoWindow = true
};
p.Start();
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();
Console.WriteLine(output);
Console.ReadLine();
Also you can do the same without the CMD process:
string fileName = #"C:\Python27\example\hello_world.py";
Process p = new Process();
p.StartInfo = new ProcessStartInfo(#"C:\Python27\python.exe", fileName )
{
RedirectStandardOutput = true,
UseShellExecute = false,
CreateNoWindow = true
};
p.Start();
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();
Console.WriteLine(output);
Console.ReadLine();

I cannot test it personally at the moment, but I found some people using Python.CreateEngine() in their code, example:
Microsoft.Scripting.Hosting.ScriptEngine engine =
IronPython.Hosting.Python.CreateEngine();
This line was taken from this SO question.
You can also check this article with example class using python code. It also uses Python.CreateEngine().

i have tried the following code and it seems to solve my problem:
Process p = new Process();
string cmd = #"python filepath & exit";
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.RedirectStandardInput = true;
p.Start();
StreamWriter myStreamWriter = p.StandardInput;
myStreamWriter.WriteLine(cmd.ToString());
myStreamWriter.Close();
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();
Console.ReadLine();

redirect any results in command prompt to richtext box

I need to redirect any results in command prompt to richtext box. Can any one provide me the necessary steps. This is how i start my command prompt.
ProcessStartInfo psi = new ProcessStartInfo
{
FileName = "cmd",
Arguments = #"/k ""C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat""",
};
Process.Start(psi);

var process = new Process
{
StartInfo = new ProcessStartInfo("cmd.exe", "/C dir c:")
{
RedirectStandardOutput = true,
UseShellExecute = false,
}
};
process.Start();
string output = process.StandardOutput.ReadToEnd();
process.WaitForExit();
Console.WriteLine(output);
EDIT: Then you can try this
var process = new Process
{
StartInfo = new ProcessStartInfo("cmd.exe")
{
RedirectStandardOutput = true,
RedirectStandardInput = true,
UseShellExecute = false,
}
};
process.Start();
// Discard "Microsoft windows all rights reserved etc.
while (process.StandardOutput.ReadLine() != "") ;
// Run command
process.StandardInput.WriteLine("dir c:");
// Skip command entered
process.StandardOutput.ReadLine();
// And exit
process.StandardInput.WriteLine("exit");
process.WaitForExit();
string output = process.StandardOutput.ReadToEnd();
Console.WriteLine(output);

You're going to want to redirect the stdout stream from the Process. I don't remember the exact properties and methods involved, but take a look through the MSDN documentation on Process.
