We have implemented a number of scenarios using different approaches and we’ve learned how to slice arrays efficiently. In this article, we introduced array slicing in C#. But it is not the case when we use it on a Span. One thing worth mentioning is if we use the range operator to work with arrays, it allocates new arrays. We can also see that these boundaries don’t work in the backward direction, so slice5 throws an ArgumentOutOfRangeException. This is because the outer loop iterates O (nm) times (note the i- inside the loop, which happens every time the letter b needs to be removed), and the splice operation requires shifting or renumbering O (m) elements in yArr after index i. Var slice5 = array // Throws ArgumentOutOfRangeExceptionĪs we see, we can use either, both, or no operands. For a dynamic array or a hashtable, then the time complexity for just the splice operations is O (nm²). Var slice3 = array // From the index 1 to index 2 Var slice2 = array // From the start to index 1 Var slice1 = array // From index 2 to the end So let’s import LINQ and consume these two methods: var posts = new string This is known as pagination and is achieved using two LINQ methods Skip() and Take(). Let’s say we have an array of ten posts and we only want to return five of them to the user, with the intention to return the rest of them on demand. The splice should be used when you want to modify the original array by removing elements and adding new elements.Now, let’s jump into code to see how to slice arrays in C# in action. The purpose of the slice is to get only selected elements from array and it doesn't modify the original array. The syntax of using splice is array.splice(startingIndex, removeCounter, newElement(s)) You can remove specified elements as well as add new elements at the same time. You can add a new element in an array using splice on a specific index Splice can also return the selected elements from the array same as the slice but it modifies the original array.
