c# - ConsoleTraceListener(Boolean) - Passing in a string

Question

I set up a TraceListener using this XML:

<add name="RuntimeDeploymentConsoleListener"
      type="System.Diagnostics.ConsoleTraceListener"
      initializeData="C:\Users\Administrator\Desktop\TraceSourceLogs.log">
</add>

I then realised that the initializeData attribute is the string passed to the constructor for the specified class. However the constructor for ConsoleTraceListener takes a Boolean. So why does this not throw an Exception at runtime when it tries to convert that string to a Boolean?
