While I was cleaning up some legacy code I found an overly complex usage of String.Split() in several places:

1
2

var sentence = "Hello World!";
var words = sentence.Split(new char[] { ' ' });

If you take a look at the available overloads on Split() you may miss the params keyword. In fact it isn’t even visible on the overview page:

But if you take a closer look on Split(char[]) you will see this:

The params keyword tells you that the method accepts any number of arguments of type char. So you could also provide only one, which will simplify the given sample to:

1
2

var sentence = "Hello World!";
var words = sentence.Split(' ');
