How to Execute multiple commands in Process

I have a list of a thousand items, Each of these items must be checked by the CMD.exe, With the help of the following code, I can check an item by CMD
var p = new Process
{
StartInfo =
{
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = true,
FileName = "cmd",
Arguments = $"list {Id}"
}};
p.Start();
var _Data = await p.StandardOutput.ReadToEndAsync();
But the question is, I want all of these items to be checked quickly by CMD, I'm currently doing this as follows
foreeach(var item in list)
{
var p = new Process
{
StartInfo =
{
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = true,
FileName = "cmd",
Arguments = $"list {item}"
}};
p.Start();
var _Data = await p.StandardOutput.ReadToEndAsync();
}
But it takes a long time to do this

You can redirect standard input and use a StreamWriter to write to it:
Process p = new Process();
ProcessStartInfo info = new ProcessStartInfo();
info.FileName = "cmd.exe";
info.RedirectStandardInput = true;
info.UseShellExecute = false;
p.StartInfo = info;
p.Start();
using (StreamWriter sw = p.StandardInput)
{
if (sw.BaseStream.CanWrite)
{
sw.WriteLine("mysql -u root -p");
sw.WriteLine("mypassword");
sw.WriteLine("use mydb;");
}
}

Process Get the outpout of a CMD command

Im trying to get the outpout of my CMD command and i get the wrong outpout:
here's my cmd command : cm whoami
here's the outpout i should get (CMD outpout) :
C:\Users\Joevin>cm whoami
JoevinFerret
here's my code :
Process process = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = "cmd.exe",
Arguments = "cm whoami",
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = true
}
};
process.Start();
string outpout = process.StandardOutput.ReadLine();
here's the outpout that i get :
outpout = "Microsoft Windows [Version 10.0.19041.804]"

Thanks to Mathias.R and Christian.K i have been able to find a solution.
Here's my code:
Process process = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = "cmd.exe",
Arguments = "/c cm whoami",
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = true
}
};
process.Start();
string outpout = process.StandardOutput.ReadToEnd();
process.WaitForExit();

ProcessStartInfo Verb runas not working

What is wrong with the following code?
ProcessStartInfo startInfo = default(ProcessStartInfo);
startInfo = new ProcessStartInfo(SetupProgramPath)
{
UseShellExecute = true,
Verb = "runas",
WindowStyle = ProcessWindowStyle.Normal,
CreateNoWindow = false
};
Process.Start(startInfo);
It is expected to prompt for credentials but nothing shows up. The system has the UAC enabled and not supposed to be changed.
I appreciate your help in this one. Thank you in advance.

I have worked this out with the following code
ProcessStartInfo startInfo = default(ProcessStartInfo);
startInfo = new ProcessStartInfo(SetupProgramPath)
{
UseShellExecute = true,
Verb = "runas",
WindowStyle = ProcessWindowStyle.Normal,
FileName = "msiexec",
Arguments = "/i \"" + SetupProgramPath + "\"",
CreateNoWindow = false
};
Process.Start(startInfo);

If you want to ask the user to enter credentials of a different user, then use "runasuser":
ProcessStartInfo startInfo = new ProcessStartInfo(SetupProgramPath)
{
UseShellExecute = true,
Verb = "runasuser",
WindowStyle = ProcessWindowStyle.Normal,
CreateNoWindow = false
};
Process.Start(startInfo);

use mongodb_name does not work in C# Process

I regular use command
use some_mongodb
to create new database from command prompt on windows
it seems that this command does not work when you want to execute this in C# process
I have the following code trying to create mongo database from C#
ProcessStartInfo startInfo = new ProcessStartInfo
{
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
RedirectStandardInput = true,
WorkingDirectory = _mongoBinDir,
FileName = "mongo.exe",
Arguments = "use " + databaseTxt.Text
};
_mongoInsertProcess = new Process
{
StartInfo = startInfo
};
_mongoInsertProcess.Start();
string stderrStr = _mongoInsertProcess.StandardError.ReadToEnd();
string stdoutStr = _mongoInsertProcess.StandardOutput.ReadToEnd();
stdoutStr variable get value
"MongoDB shell version: 3.2.1 connecting to: use
2016-04-07T15:28:52.875+0200 E - [main] file [some_db] doesn't
exist failed to load: some_db"
Please advise on this.

use some_db isn't a valid argument. Just pass the name of the database i.e:
ProcessStartInfo startInfo = new ProcessStartInfo
{
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
RedirectStandardInput = true,
WorkingDirectory = _mongoBinDir,
FileName = "mongo.exe",
Arguments = databaseTxt.Text
};

save my gpg file to a different directory

RedirectStandardError = true,
RedirectStandardInput = true,
RedirectStandardOutput = true
};
startInfo.FileName = "gpg.exe";
