How do I do implement a trace and assert?

Use a conditional attribute on the method, as shown below:

class Debug

{

[conditional("TRACE")]

public void Trace(string s)

{

Console.WriteLine(s);

}

class MyClass

{

public static void Main()

{

Debug.Trace("hello");

}

In this example, the call to Debug.Trace() is made only if the preprocessor symbol TRACE is defined at the call site. You can define preprocessor symbols on the command line by using the /D switch. The restriction on conditional methods is that they must have void return type.

Well, you cant add the namespace System.Diagnostics.ConditionalAttribute. Actually you need to add the namespace System.Diagnostics and capitalise "Conditional" like so:

using System;
using System.Diagnostics;

namespace Debug
{
   class Debug
   {
   [Conditional("TRACE")]
   public void Trace(string s)
   {
   Console.WriteLine(s);
   }
   }
}
