how i can execute CMD command in c# console application?

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?


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\"");


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

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;


/* execute "dir" */


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);
