I need to execute the below command prompt in Visual studio 2010.

Cmd: Httputil.exe "aws s3 cp" C:\TEMP\Test1.TXT <s3 bucket="" name="">

Here HttpUtil is the Visual studio project name. I need to pass
"aws s3 cp" C:\TEMP\Test1.TXT <s3 bucket="" name=""> to .net coding and execute the command.

Please anyone help.

What I have tried:

I tried with Filestream readwrite access. It is not working. Can anyone help?

C#

args2[0] = aws args2[1] = s3 args2[2] = cp args2[3] = C:\TEMP\Test1.TXT
args2[4] = <s3 bucket="" name="">

Process objProcess = new Process();
objProcess.StartInfo.FileName = "cmd.exe";
objProcess.StartInfo.Arguments = args2[0] + " " + args2[1] + " " + args2[2] + " " + args2[3] + " " + args2[4];
objProcess.StartInfo.CreateNoWindow = false;
objProcess.Start();
objProcess.Close();

It is opening the command prompt only. Not executing and not closing.

Solution 1

Have a look here:
Process.Start Method (System.Diagnostics) | Microsoft Docs[^]

For your concrete problem this will look like this.

C#

var process = new Process
{
	StartInfo = new ProcessStartInfo("Httputil.exe")
	{
		Arguments = "\"aws s3 cp\" C:\\TEMP\\Test1.TXT <s3 bucket=\"\" name=\"\""
	}
};

process.Start();

Why do you call Close immediately after Start?

Hi,
I am not able to understand your answer. Can you explain please?

This is a link to the original Microsoft documentation.
There are also lots of examples how to start a process.
Especially
https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.process.start?view=net-5.0#System_Diagnostics_Process_Start_System_Diagnostics_ProcessStartInfo_
might be interesting for you.
Just search for OpenWithStartInfo()

Hi,
Thanks for your response.
But it is not working. The command prompt will open and the parameters i passed but it is not showing and command prompt not closing.

Not working is the most useless description available on earth.
Show us your source code, maybe we can see what is wrong.

args2[0] = aws args2[1] = s3 args2[2] = cp args2[3] = C:\TEMP\Test1.TXT
args2[4] = <s3 bucket="" name="">

Process objProcess = new Process();
objProcess.StartInfo.FileName = "cmd.exe";
objProcess.StartInfo.Arguments = args2[0] + " " + args2[1] + " " + args2[2] + " " + args2[3] + " " + args2[4];
objProcess.StartInfo.CreateNoWindow = false;
objProcess.Start();
objProcess.Close();

It is opening the command prompt only. Not executing and not closing.

This is my code.

Those are not command-line arguments for the cmd.exe program:
cmd | Microsoft Docs[^]

Either change the code to set the FileName to aws.exe and remove aws from the arguments, or use the /c argument to specify that the remainder of the string is a command to execute.

You are right the wrong filename is used.

Have a look at the updated solution.

I will check and give the status.
