C#- splitting a string with another string (string delimeter)

Splitting a string with another string should be a simple matter you might think. However it is not as intuitive as you might think. I would have thought that a simple .split() method would have to be called with a string as parameter, but that was not the case. Below is a way to do it.

var text = "first half SpltOnThis second half";
var splittedString = text.Split(new[] { "SpltOnThis" }, StringSplitOptions.None);
//splittedString will contain: "first half " and " second half".

In the above we use an overload of the Split method, which takes an array of strings to split on, in the above we only give it one string.

And here is an example where I have wrapped it in a nice extension method:

public static string[] Split(this string str, string delimeter)
{
   return str.Split(new[] { delimeter }, StringSplitOptions.None);
}

That is it, please leave a comment down below if you found this helpful :)
