Delegate, Lambda and more … C# versions comparative

C# event handler delegate changed according to C# versions.

Here is a sample, based on UnhandledException event

in the beginning was

d.UnhandledException += new UnhandledExceptionEventHandler(d_UnhandledException);
//...

void d_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
  Console.WriteLine("Ouch!");
}

currently, lambda version is quicker to write and easier to understand

d.UnhandledException += (sender, e) => { Console.WriteLine("Ouch!"); };

ain’t it ? 😉

Maybe Visual Studio Intellisense helps you with old style form, and you have to write the full version manually (do you snippet ?).

In Initializing things in C# post I found a quick reference to event handler, anonymous type, lambda, object initialization, etc
with clearfull samples according to C# versions 1, 2 and 3.

Have a nice reading 😉

While I was looking for infos about vm settings (cpu multi core, multi cpu, …) I found this helpfull document “Performance Best Practices for VMware vSphere™ 5.0“.
Well it wasn’t very appropriate to my need, but it helped empowering my knowledge  🙂 because best practices are valid in variuos scenarios. 😉
