Redirect console.writeline from windows application to a string

Question

I have an external dll written in C# and I studied from the assemblies documentation that it writes its debug messages to the Console using Console.WriteLine.

Answer 1

It basically amounts to the following:

var originalConsoleOut = Console.Out; // preserve the original stream
using(var writer = new StringWriter())
{
    Console.SetOut(writer);

    Console.WriteLine("some stuff"); // or make your DLL calls :)

    writer.Flush(); // when you're done, make sure everything is written out

    var myString = writer.GetStringBuilder().ToString();
}

Console.SetOut(originalConsoleOut); // restore Console.Out

So in your case you'd set this up before making calls to your third-party DLL.
