How to Redirect Console Output to a File in C# Posted on January 5, 2008 by Hai 5 I encountered the need to redirect the console output to a file in my attempt to automate testing of functions which does not return any value but writes to the console. Basically, we need to save the old output (Console.Out) before assigning the output to a file stream by means of Console.SetOut(). After the test, I also need to restore the console output. After doing this for a while, it gets old and I told myself, “Self, I can create a simple class to simplify this task.” In my vision, output redirect should be easy, simple, and practical. The user should not have to remember the details such as which data type to use (TextWriter, FileStream, StreamWriter, …), or which steps to take. Thus, I created OutToFile, a simple class which encapsulate this idea. Using OutToFile is … you guessed it, easy: The source code for this class is available, you are free to use it, but I reserve the bragging right .

Eliot December 15, 2009 This is exactly what I was looking for! We have tons of console print debugging statements in our XNA game engine: http://pantherengine.sourceforge.net/ With this class I believe we can catch all of them and redirect them to a file. Thanks for allowing us to use this code. If we wind up using it it will be noted that it is not under the project’s Apache 2.0 license. 2. Edgar September 17, 2010 Hello Hai, Do you know how I may be able to output this process to a txt or log file? Process ps = new Process(); ps = Process.Start(NUNIT_CONSOLE, path + “\\” + nunitFile + ” /include:\”" + sTestConcepts + “\”" + “/out:C:/Users/Edgar/Documents/TestResults.txt” ); //wait until the process is done while (!ps.HasExited) System.Threading.Thread.Sleep(100); testConcepts = new ArrayList(); Thank you in advance for your help! -Edgar 3.

See if something like this can help: http://channel9.msdn.com/forums/Coffeehouse/250664-C-Execute-External-App-and-capture-output/ If not, google for C# process capture output and you will probably find something that works. Cheers. 4. Edgar September 20, 2010 Hai, Thank you for your help and quick response! The link you provided was very helpful. I ended up using a stream writer and it works now. I am having trouble with the console freezing while running (it is running multiple processes) but this is a different issue. I appreciate the help! Cheers 1 Trackback For This Post 1.
