Hi,
I have a output redirect problem in NAnt.
I defined a custom NAnt task. Inside it, I have the following code:
TextWriter standardOut = Console.Out;
TextWriter standerdError = Console.Error;
int exitValue;
using (TextWriter newOutWriter = File.CreateText(output),
newErrorWriter = newOutWriter)
{
Console.SetOut (newOutWriter);
Console.SetError(newErrorWriter);
exitValue = ExternalProgram.ExecuteProgram(command,
arguments);
}
Console.SetOut(standardOut);
Console.SetError(standerdError);
Basicly, it will execute an external program then redirect that program's
output to a file of which the name is stored in the variable - output. The
ExecuteProgram method is defined as below.
public class ExternalProgram
{
public static int ExecuteProgram(string program, string arguments)
{
Process process = new Process();
process.StartInfo.FileName = program;
process.StartInfo.Arguments = arguments;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.CreateNoWindow = true;
process.Start();
process.WaitForExit();
return process.ExitCode ;
}
}
Put the above code outside NAnt task, they work as expected. The output is
redirected to a file. But using the above code in NAnt custom task, nothing
is redirected to the file. Could someone tell me the reason and give me a
solution? Thank you in advance.
