How to run sourcecode compiled from C in C# - c#

I have a simple sourcecode written in C .
After compiling with GCC via command :
gcc hello.c -o hello
I have file hello .
I want to use C# to run the above hello file, what should I do?
I tried the following but it didn't work.
Contents of file hello.c
#include <stdio.h>
int main()
{
printf("Hello, World!");
return 0;
}
Contents in C#
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C D:\\src\\testCompileCUsingGCC\\src\\mrtbtostr\\hello";
process.StartInfo = startInfo;
process.Start();
Results after running . Error content : is not recognized as an internal or external command,
operable program or batch file
This is the result when running the compiled hello file manually
After run command : gcc hello.c -o hello.exe

Check whether the path of hello.exe is correct
If you want to see the result in cmd, change
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; to startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;

Unable to start a command line with spaces from C#

The command line I need to execute is
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\devenv.exe" /Run "C:\unity\unity\MRTK Tutorial\Builds\MRTK Tutorial.sln"
This works from a windows command line without issues,
I formatted it into a string for visual studio
When running from C# this command never executes and the contents of result are ""
System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("C:\\Program Files(x86)\\Microsoft Visual Studio\\2019\\Enterprise\\Common7\\IDE\\devenv.exe", " /Run \"C:\\unity\\unity\\MRTK Tutorial\\Builds\\MRTK Tutorial.sln\"");
// The following commands are needed to redirect the standard output.
// This means that it will be redirected to the Process.StandardOutput StreamReader.
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
// Do not create the black window.
procStartInfo.CreateNoWindow = true;
// Now we create a process, assign its ProcessStartInfo and start it
System.Diagnostics.Process proc = new System.Diagnostics.Process();
You can try the following code to use c# to execute devenv.exe.
var devEnvPath = #"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\devenv.exe";
string SolutionFile = #"D:\Test\testconsole\testconsole.sln";
ProcessStartInfo startInfo = new ProcessStartInfo(devEnvPath);
startInfo.Arguments = "/Run " + SolutionFile;
Process process = new Process();
process.StartInfo = startInfo;
process.Start();
process.WaitForExit();
Console.ReadKey();
Based on my test, the above code will open vs2019 and open the startup project.

CMD log to file not working for Geth.exe

I'm using the below code to log output of a cmd call to a file however it's not working at times.
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
//startInfo.Arguments = "/C dir C:\\ >c:\\temp\\dir.txt";
startInfo.Arguments = "/C \"C:\\Program Files\\Geth\\geth.exe\" --exec \"web3.eth.getBalance(web3.eth.accounts[0]);\" attach >c:\\temp\\out.txt";
process.StartInfo = startInfo;
process.Start();
The simple dir works fine.
Using the Ethereum geth.exe without --exec works fine.
However once I include the --exec argument the output is blank. Both commands work fine and produce output if manually called in cmd.exe.
"C:\Program Files\Geth\geth.exe" attach >c:\temp\out.txt
"C:\Program Files\Geth\geth.exe" --exec "web3.eth.getBalance(web3.eth.accounts[0]);" attach >c:\temp\out.txt
I see you found a workaround, but for others:
process.Start();
process.WaitForExit();
You have to wait for the process to exit.

Running a program through C# with cmd doesn't work

I'm trying to run JMeter through C# with cmd but it just opens cmd and doesn't run anything.
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
//startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.WorkingDirectory = "D:";
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/k D:\\jmeter\\apache-jmeter-2.13\\bin\\ApacheJMeter.jar -n -t D:\\Delo\\dokument.jmx";
process.StartInfo = startInfo;
process.Start();
That code just opens the cmd and nothing happens. I've tried changing the working directory but it doesn't work. If I don't set the working directory, cmd just open at my debug directory. This does work if I start it directly from cmd (without C#).
Solved with this: a link
I'm not exactly sure what are you trying to achieve, and why you aren't using System.Diagnostics ? But I have a suggestion if I understood you right:
> System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
> startInfo.WorkingDirectory = "D:";
> startInfo.FileName = #"D:\jmeter\apache-jmeter-2.13\bin\ApacheJMeter.jar";
> startInfo.Arguments = "";
> System.Diagnostics.Process.Start(startInfo);
>
> System.Diagnostics.ProcessStartInfo startInfo2 = new System.Diagnostics.ProcessStartInfo();
> startInfo2.WorkingDirectory = "D:";
> startInfo2.FileName = #"D:\Delo\dokument.jmx";
> startInfo2.Arguments = "";
> System.Diagnostics.Process.Start(startInfo2);
I don't think you will be able to run .jar file directly via cmd interpreter, go for the following alternatives:
use jmeter.bat wrapper script
call Java executable like: path\to\java.exe -jar D:\\jmeter\\apache-jmeter-2.13\\bin\\ApacheJMeter.jar ...
I would also suggest using -l command line argument so .jtl results file could be generated.
See How Do I Run JMeter in Non-GUI Mode? article for details. I also believe that Full list of command-line options will be helpful in your case.

Java Keytool and C#

I'm trying to make a program in C# to run an automatic key tool and generate a key for Android development but I have some problems that I can't figure out.
Code in C#:
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo =
new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
startInfo.FileName =
Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles)
+ "\\Java\\jdk1.7.0_40\\bin\\keytool.exe";
startInfo.Arguments =
"-exportcert -alias androidkey -keystore d:\\debug.keystore > C:\\asd.txt";
process.StartInfo = startInfo;
process.Start();
On the command line it tells me this:
Illegal option: >keytool -exportcert [OPTION] ...
And I tried to run the exact command in the key tool manually and there was no problem.

sending command to cmd through c#

I want to execute a command to lock the drive through bit locker when button is clicked. How to do this? I'm new in c#
The command is:
manage-bde -lock x:
How it will be send to console? here is the code
private void btnlock_Click(object sender, EventArgs e)
{
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C manage-bde -lock "+textBox1.Text+":";
process.StartInfo = startInfo;
process.Start();
}
You can use the Process class in System.Diagnostics namespace.
It should be something like this:
System.Diagnostics.Process.Start("manage-bde", "-lock x:");
The command isn't being executed because your command line doesn't know where to find the manage-bde program.
All you need to do is add the full path of the file like so:
startInfo.Arguments = #"/C C:\Program Files\Foo\manage-bde.exe -lock "+textBox1.Text+":";
Note: I'm not sure if the .exe part is necessary, but it doesn't hurt adding it in. Also, make sure you either use 2 backslashes (\\) or use the # before the quotation mark at the start.
