How to get execution command window in c#

Question

I execute a command from my C# App.

It runs fine but sometimes I get errors.

My problem is that I cannot see which is the error or any other text in the command window.

It is just blank.

Is there any way I can make the text show up in the execution time same as it is appeared here?

Here is my code:

        var processInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
        //processInfo.CreateNoWindow = true;
        processInfo.UseShellExecute = false;
        processInfo.RedirectStandardError = true;
        processInfo.RedirectStandardOutput = true;
        processInfo.WorkingDirectory = workingFolder;

        var process = Process.Start(processInfo);

        process.OutputDataReceived += (object sender, DataReceivedEventArgs e) => 
        Console.WriteLine("output>>" + e.Data);//MessageBox.Show(e.Data);
        
        process.BeginOutputReadLine();

        process.ErrorDataReceived += (object sender, DataReceivedEventArgs e) => 
        Console.WriteLine("error>>" + e.Data);//MessageBox.Show(e.Data);
        process.BeginErrorReadLine();

        process.WaitForExit();

        Console.WriteLine("ExitCode: {0}", process.ExitCode);
        process.Close();

There is nothing wrong with your code, the problem is that you run your program in the wrong path.

Follow these steps to find the path of your app:

Then, in the cmd.exe go to the path with bunch of cd commands.
Here is the code:

var command = "echo hello world"; // < ------ example
var processInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
//processInfo.CreateNoWindow = true;
processInfo.UseShellExecute = false;
processInfo.RedirectStandardError = true;
processInfo.RedirectStandardOutput = true;
        

The output:

output>>hello world
output>>
error>>
ExitCode: 0
Press any key to continue . . .

Also, you can run your app with Ctrl + F5
I know these are so obvious but it's worth to mention them.

Update

You should specify a command, maybe you don't set any command or your command has ~no output~

Update2

I change the code, when the user send args to myapp.exe, it directs it to run.

static void Main(string[] args)
{

    var command = string.Join("", args);
    var processInfo = new ProcessStartInfo("cmd.exe", "/c " +  command);
    ...

Output:

C:\Users\Mahan\Source\Repos\ConsoleApp11\ConsoleApp11\bin\Debug>myapp.exe echo hello

output>>hello world
output>>
error>>
ExitCode: 0
