The following code example formats the results of a function and uses the WriteLine(String) method to write the last part of the message to a DefaultTraceListener.

// Compute the next binomial coefficient.   
// If an exception is thrown, quit. 
decimal result = CalcBinomial(possibilities, iter);
if (result==0) {return;}

// Format the trace and console output. 
string binomial = String.Format("Binomial( {0}, {1} ) = ", possibilities, iter);
Console.WriteLine("{0} {1}", binomial, result);
