Run cmd.exe with C#,needs to input "Y"

Question

I want to run cmd command:"net use * /delete" with System.Diagnostics.Process,but the command needs to input "Y" or "N".

here is my code:

Process proc = new Process();
proc.StartInfo.FileName = "cmd.exe";
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardInput = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.CreateNoWindow = true;
string dosLine = "/C echo y | net use * /delete";
proc.StartInfo.Arguments = dosLine;
proc.Start();

the codes do not work. i also tried this:

proc.StandardInput.WriteLine("net use * /delete");
proc.StandardInput.WriteLine("Y");

still not work

what should i do?

net use takes a /y flag, so you can just pass that instead. You don't need to input it. You could also simplify your code like so:

Process proc = new Process();
proc.StartInfo.FileName = "net";
proc.StartInfo.Arguments = "use * /delete /y";
proc.StartInfo.UseShellExecute = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.CreateNoWindow = true;
proc.Start();

Run cmd.exe with C#,needs to input "Y"
