What does list int mean in C#?

List is supposed to be of value type and not reference type. List has to be passed by ref keyword if its value has to be persisted between function calls. So this means it is displaying a value type behavior similar to int. But List has to be initialized by a new operator.

How do you make a list of integers in C#?

There’s no “shortcut” (list initialization) in C# 2.0 to do just that, either new up the list and then add the numbers manually via myValues. Add, or you could do the following: int[] arrMyValues = new int[] {1, 2, 3}; List myValues = new List(arrMyValues);

How do I return a value from a list in C#?

Return a list from a method in C#

  1. using System. Collections. Generic;
  2. public List findNeighbours()
  3. {
  4. List localFish = new List();
  5. foreach(GameObject fish in fishSchool)
  6. {
  7. float distance = Vector3. Distance (transform. position, fish. transform. position);
  8. if (distance <= nDistance)

How does list work in C#?

Lists in C# are very similar to lists in Java. A list is an object which holds variables in a specific order. The type of variable that the list can store is defined using the generic syntax.

How do I create an int list?

Below are the following ways to initialize a list:

  1. Using List.add() method. Since list is an interface, one can’t directly instantiate it.
  2. Using Arrays. asList()
  3. Using Collections class methods. There are various methods in Collections class that can be used to instantiate a list.
  4. Using Java 8 Stream.
  5. Using Java 9 List.

Why do we use list in C#?

A List class can be used to create a collection of any type. For example, we can create a list of Integers, strings and even any complex types. Unlike arrays, a List can grow in size automatically in other words a list can be re-sized dynamically but arrays cannot. List is a generic type.

Can we return list in C#?

There is no need to initialize the variable to an empty list that will get replaced immediately. If the list is very large or you simply need to traverse it, you can use the yield keyword and change the return type of the function to IEnumerable , though your current design doesn’t fit this pattern.

What is list in C?

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.Collection.Generic namespace.

What is the use of the public keyword in a class?

Thank you. The public keyword is an access modifier for types and type members. Public access is the most permissive access level. There are no restrictions on accessing public members, as in this example: class SampleClass { public int x; // No access restrictions. } See Access Modifiers and Accessibility Levels for more information.

Is List a reference type?

A List is a generic reference type, you are using it with a value type int. But it is still a reference type. Show activity on this post. In addition to the mistaken assumptions dealt with in other answers, you say: List has to be initialized by a new operator… This implies a reference type behavior.

Does list have to be initialized by the new operator?

List has to be initialized by a new operator… This implies a reference type behavior. No, in C# the new operator is just the syntax for calling the constructor of a type. It’s used for both reference and user-defined value types ( struct s). List is a reference type.
