directx - C# DX What is this param mean? -

i ran while using slimdx

messagepump.run(form, () => { });

what () => { } do?

the expression () => {} empty lambda expression. function messagepump.run defined as:

public static void run( form form, mainloop mainloop )

mainloop defined as:

public delegate void mainloop()

so delegate not expects parameters. when pass () => {} method nothing like:

public void mainloopimpl() {     //empty method }

now create mainloop instance:

var mloop = new mainloop(mainloopimpl); //or alternative syntax mainloop mloop = mainloopimpl;  //call run  messagepump.run(form, mloop);

details declaring, creating , using delegates (including lambda expression declaration way) explained in detail on this msdn page.
