Generic LinkedList T Collection Class in C# with Examples
In this article, I am going to discuss Generic LinkedList T Collection Class in C# with Examples. Please read our previous article where we discussed Generic SortedDictionary TKey, TValue Collection Class in C# with Examples. At the end of this article, you will understand the following pointers with examples.
What is LinkedList T in C#?
A LinkedList is a linear data structure used for storing the elements in a non-contiguous manner. The elements in a linked list are linked with each other using pointers. Or in other words, LinkedList consists of nodes where each node contains a data field and a reference(link) to the next node in the list. So, each node contains two parts.

Foreach Loop in C# with Examples
In this article, I am going to discuss Foreach Loop in C# with Examples. Please read our previous article where we discussed Generic Queue in C# with Examples.

What is Foreach Loop in C#?
Looping is a way to execute a statement(s) multiple times depending on the result of a condition. As long the given condition satisfies the loop executes. Once the condition failed, the loop terminates.
The Foreach Loop in C# is a different kind of loop that doesn’t include initialization, termination, and increment/decrement characteristics. It uses the collection to take values one by one and then processes them.

The foreach loop in C# is used to iterate over the elements of a collection. Here, the collection may be an array or a list or a dictionary, etc. As per the name i.e. foreach, it executes the loop body for each element present in the array or collection.

In C#, the foreach loop iterates collection types such as Array, ArrayList, List, Hashtable, Dictionary, etc. It can be used with any type that implements the IEnumerable interface.

Syntax to use Foreach Loop in C# Language:
The System.Collections.Generic namespace contains the ForEach() extension method that can be used with any built-in collection classes such as List, Dictionary, SortedList, etc.



Conversion between Array, List, and Dictionary in C#
In this article, we will discuss how to perform Conversion Between Array List and Dictionary in C#. Please read our previous article where we discussed Dictionary in C# with examples. As part of this article, we will discuss the following six things.

Convert an array to a List – Use ToList() method
Convert a list to an array – Use ToArray() method
Convert a List to a Dictionary – Use ToDictionary() method
Convert an array to a Dictionary – Use ToDictionary() method
Convert a Dictionary to an array – Use ToArray() method on the Values Property of the dictionary object
Convert a Dictionary to a List – Use the ToList() method on the Values Property of the dictionary object
