C# – Generic Collection | List Generic Collection in C# Tutorial – List Collection | – List in C#

This is C# Tutorial for using List Collection. In this tutorial video we will see how to use C# List (List in C#) and the Methods we can use in List Collection. The sample project showing in this video is developed in Visual Studio 2019 using (C#/C Sharp Language) from Microsoft.

The List is a collection of strongly typed objects that can be accessed by index and having methods for sorting, searching, and modifying list. It is the generic version of the ArrayList that comes under System.Collection.Generic namespace.

The List can do a lot of the same stuff as an Array (which also implements the IList interface by the way), but in a lot of situations, List is simpler and easier to work with. For instance, you don’t have to create a List with a specific size – instead, you can just create it and .NET will automatically expand it to fit the amount of items as you add them

C# List class represents a collection of strongly typed objects that can be accessed by index. In this tutorial, we learn how to work with lists in C# using C# List class to add, find, sort, reverse, and search items in a collection of objects using List class methods and properties.

What is C# List?
List class in C# represents a strongly typed list of objects. List provides functionality to create a list of objects, find list items, sort list, search list, and manipulate list items. In List, T is the type of objects.

What is the in ListT?
List class in represents a strongly typed list of objects. List provides functionality to create a list of objects, find list items, sort list, search list, and manipulate list items. In List, T is the type of objects.
How to create List in C#?

List is a generic class and is defined in the System.Collections.Generic namespace. You must import this namespace in your project to access the List class.

C# – List
The List is a collection of strongly typed objects that can be accessed by index and having methods for sorting, searching, and modifying list. It is the generic version of the ArrayList that comes under System.Collections.Generic namespace.
List Characteristics

List equivalent of the ArrayList, which implements IList
It comes under System.Collections.Generic namespace.
List can contain elements of the specified type. It provides compile-time type checking and doesn’t perform boxing-unboxing because it is generic.
Elements can be added using the Add(), AddRange() methods or collection-initializer syntax.
Elements can be accessed by passing an index . Indexes start from zero.
List performs faster and less error-prone than the ArrayList.

Creating a List
The List is a generic collection, so you need to specify a type parameter for the type of data it can store. The following example shows how to create list and add elements.

a generic collection is a class that is designed to hold a collection of items of a specific data type. It provides a way to store and manipulate a group of objects, such as strings or integers, in a single container.

A generic collection is “generic” because it can be used with any data type. This means that the type of data stored in the collection is not predetermined by the collection class itself but is specified by the programmer when the collection is instantiated.

The .NET Framework provides several generic collection classes, such as List Dictionary Key, TValue, Queue and Stack These classes offer a wide range of functionalities for storing, accessing, and manipulating collections of data.

The advantage of using a generic collection over a non-generic collection is that it provides type safety and performance benefits. With a generic collection, the compiler can ensure that the type of data being stored in the collection matches the type of data expected, which can help catch errors at compile time. Additionally, because a generic collection is optimized for a specific data type, it can provide better performance than a non-generic collection that has to store all data types as objects.
