Yes - replace Console.Out
. Use Console.SetOut
after creating a TextWriter
which not only dumps the requested data to the original console, but also dumps a stack trace (and timestamp, and the requested data) to a file.
Here's some code, adapted from Benjol's answer:
(Note: you will want to adapt this code depending on whether you want a stack trace after each write, or after each writeline. In the code below, each char is followed by a stack trace!)
using System.Diagnostics;
using System.IO;
using System.Text;
public sealed class StackTracingWriter : TextWriter
{
private readonly TextWriter writer;
public StackTracingWriter (string path)
{
writer = new StreamWriter(path) { AutoFlush = true };
}
public override System.Text.Encoding Encoding
{
get { return Encoding.UTF8; }
}
public override void Write(string value)
{
string trace = (new StackTrace(true)).ToString();
writer.Write(value + " - " + trace);
}
public override void Write(char[] buffer, int index, int count)
{
Write(new string(buffer, index, count));
}
public override void Write(char value)
{
// Note that this will create a stack trace for each character!
Write(value.ToString());
}
public override void WriteLine()
{
// This is almost always going to be called in conjunction with
// real text, so don't bother writing a stack trace
writer.WriteLine();
}
protected override void Dispose(bool disposing)
{
writer.Dispose();
}
}
To use this for logging both Console.WriteLine
and Debug.WriteLine to a file
, make calls like this as early as possible in your code:
var writer = new StackTracingWriter(@"C:\Temp\ConsoleOut.txt");
Console.SetOut(writer);
Debug.Listeners.Add(new TextWriterTraceListener(writer));
Note that this currently doesn't also write to the original console. To do so, you'd need to have a second TextWriter
(for the original console) in StackTracingWriter
, and write to both places each time. Debug will however continue to be written to the original console.
