C# Redirect Console Output to log file

I would like to run an executable program that takes an argument and then redirect the console output to a file. The following is how I normally do it from command line (runs nunit-console.exe, passes it MyTest.dll as an argument, and redirects the console output to outfile.log):

nunit-console.exe MyTest.dll > outfile.log 2>&1

I would like to be able to do this strictly from my C# code. The following is the code I have, but it does not work. Can you please help me (this is very urgent)???? Thank you so much!!!

           Process myprocess  = new Process();
            myprocess.StartInfo.FileName = @"c:\nunit-console.exe";
            myprocess.StartInfo.WorkingDirectory = @"c:\" ;
            myprocess.StartInfo.Arguments= "MyTest.dll -s -m";
            myprocess.StartInfo.UseShellExecute = false;
            myprocess.StartInfo.RedirectStandardOutput = true;
            myprocess.StartInfo.CreateNoWindow = true;
            StreamWriter sw = new StreamWriter(@"c:\outfile.log");
            myprocess.Start();
            sw.WriteLine(myprocess.StandardOutput.ReadToEnd());
            sw.Close();

I remember that setting RedirectStandardOutput to true is not enough. In addition you must set
UseShellExecute = false;

How to Create Failover DNS Record Sets in Route 53

Route 53 has the ability to easily configure DNS record sets specifically for failover scenarios. These failover record sets can be configured to failover to full-blown deployments in other regions or to a static HTML page that informs your customers of the issue.

myprocess.WaitForExit(); can be useful too.

you should read the stream being returned by the process before calling the WaitForExit:

Process myprocess  = new Process();
            myprocess.StartInfo.FileName = @"c:\nunit-console.exe";
            myprocess.StartInfo.WorkingDirectory = @"c:\" ;
            myprocess.StartInfo.Arguments= "MyTest.dll -s -m";
            myprocess.StartInfo.UseShellExecute = false;
            myprocess.StartInfo.RedirectStandardOutput = true;
            myprocess.StartInfo.CreateNoWindow = true;
            StreamWriter sw = new StreamWriter(@"c:\outfile.log");
            myprocess.Start();
            string strOutput = myprocess.StandardOutput.ReadToEnd();
            myprocess.WaitForExit();
            sw.WriteLine(strOutput);
            sw.Close();

I tried the above code, but it is not working for me yet. It prints to the oufile.log what seems to be rules on how to run nunit-console.exe with arguments, but I do not know how to apply it. The MyTest.dll is a library of NUnit tests that I am trying to run. I also saw on the following website an example of running an .exe file and passing args to it it the way I think I want to, but I'm not sure how to apply it (compiler.StartInfo.Arguments = "/r:System.dll /out:sample.exe stdstr.cs") .

Can you please provide code? Thank you

It is correct
myprocess.StartInfo.Arguments= "MyTest.dll -s -m";
you can try to write
myprocess.StartInfo.Arguments= "\"MyTest.dll -s -m\"";
