It's very simple to make a mysqldump in cmd on windows, simply:

Open cmd and put type mysqldump uroot ppassword database > c:/data.sql

This results in an SQL dump file for the desired database.

I'm writing a console application so I may run this command:

-uroot -ppass databse  > location\data.sql

I tried the following code to no avail:

System.Diagnostics.ProcessStartInfo procStartInfo =
    new System.Diagnostics.ProcessStartInfo("cmd", "/c " + cmd);

How might I start a cmd process and send my command successfully?

  • You should elaborate what is the error, what happens.. maybe CMD can't be found try to put full path in there Commented Apr 6, 2011 at 12:08
  • Is it safe to add the password on the command line...? Commented Apr 7, 2011 at 7:19

Reset to default

Process cmd = new Process();

cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.UseShellExecute = false;

cmd.Start();

/* execute "dir" */

cmd.StandardInput.WriteLine("dir");
cmd.StandardInput.Flush();
cmd.StandardInput.Close();
Console.WriteLine(cmd.StandardOutput.ReadToEnd());

Is there a reason why you don't call mysqldump directly?

ProcessStartInfo procStartInfo = 
    new ProcessStartInfo("mysqldump", "uroot ppassword databse > c:/data.sql");

If there is a reason, your code should look like this:

ProcessStartInfo procStartInfo = 
    new ProcessStartInfo("cmd", 
        "/c \"mysqldump uroot ppassword databse > c:/data.sql\"");

Changes:

  • You where missing "mysqldump" in your cmd variable.
  • You should put the command to be executed in the command line into quotes.

Do you run Process.Start(psi) with the ProcessStartInfo instance you have just created?

Anyway, the following should do the work:

string commandToExecute = @"c:\windows\system32\calc.exe";
Process.Start(@"cmd", @"/c " + commandToExecute);

To use Powershell,

Process cmd = new Process();

cmd.StartInfo.FileName = "powershell.exe";
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.UseShellExecute = false;

cmd.Start();

/* execute "dir" */

cmd.StandardInput.WriteLine("dir");
cmd.StandardInput.Flush();
cmd.StandardInput.Close();
Console.WriteLine(cmd.StandardOutput.ReadToEnd());

when you wish to run several commands in CMD say,

cmd.StandardInput.WriteLine("dir && dir");

while in powershell, use:

cmd.StandardInput.WriteLine("dir;dir");
