C# Class Zephyr.DesignByContract.Check

Design by Contract checks developed by http://www.codeproject.com/KB/cs/designbycontract.aspx. Each method generates an exception or a trace assertion statement if the contract is broken.
This example shows how to call the Require method. Assume DBC_CHECK_PRECONDITION is defined. public void Test(int x) { try { Check.Require(x > 1, "x must be > 1"); } catch (System.Exception ex) { Console.WriteLine(ex.ToString()); } } If you wish to use trace assertion statements, intended for Debug scenarios, rather than exception handling then set Check.UseAssertions = true You can specify this in your application entry point and maybe make it dependent on conditional compilation flags or configuration file settings, e.g., //#if DBC_USE_ASSERTIONS Check.UseAssertions = true; //#endif You can direct output to a Trace listener. For example, you could insert Trace.Listeners.Clear(); Trace.Listeners.Add(new TextWriterTraceListener(Console.Out)); or direct output to a file or the Event Log. (Note: For ASP.NET clients use the Listeners collection of the Debug, not the Trace, object and, for a Release build, only exception-handling is possible.)
