IEnumerable VS IList In C #:
=================
In LINQ to query data from collections, we use IEnumerable and IList for data manipulation. IEnumerable is inherited by IList, hence it has all the features of it and except this, it has its own features. IList has below advantage over IEnumerable.

IList:
====
1. IList exists in System.Collections Namespace.
2. IList is used to access an element in a specific position/index in a list.
3. Like IEnumerable, IList is also best to query data from in-memory collections like List, Array etc.
4. IList is useful when you want to Add or remove items from the list.
5. IList can find out the no of elements in the collection without iterating the collection.
6. IList supports deferred ex*****on.
7. IList doesn't support further filtering.

IEnumerable:
=========
1. IEnumerable exists in System.Collections Namespace.
2. IEnumerable can move forward only over a collection, it canโ€™t move backward and between the items.
3. IEnumerable is best to query data from in-memory collections like List, Array etc.
4. IEnumerable doesn't support add or remove items from the list.
5. Using IEnumerable we can find out the no of elements in the collection after iterating the collection.
6. IEnumerable supports deferred ex*****on.
7. IEnumerable supports further filtering.

==> Static Class In C #

1. A static class is a class that cannot be instantiated.
2. You canโ€˜t create an object for the static class
3. A static class can contain static members only.

# Static Members:
There are two types of C # static class members :
1. static and
2. non-static.

Static Members:
If you use the "static" keyword for the declaration of a field / property or a method, then it is called a "Static member".

Example:
//static data members
public static string CollegeName = "CoderOxygen College of Technology";

Non-static members:
This is the default type for all the members. If you do not use the "static" keyword for the declaration of a field / property or a method, then it can be called a "Non-static member".

Example:
//non-statcic data members
public string StudentName;
