C# 8.0 introduced a new predefined structure that is known as Index struct. This struct is used to represent a type that can be used as an index of a collection or sequence that starts from either start or end. It provides a new index style to access elements that is ^ operator. This operator is used to find the last elements of the specified collection or sequence. Also with the help of Index struct you are allowed to create a variable of the index type.

|Index(Int32, Boolean)||It is used to initialize a new Index with a specified index position and a value that indicates if the index is from the start or the end of a collection.|
|End||It is used to get an Index that points beyond the last element.|
|IsFromEnd||It is used to get a value that indicates whether the index is from the start or the end.|
|Start||It is used to get an Index that points to the first element of a collection.|
|Value||It is used to get the index value.|
|Equals()||It is used to check whether the given index is equal to another index or not.|
|FromEnd(Int32)||It is used to create an Index from the end of a collection at a specified index position.|
|FromStart(Int32)||It is used to create an Index from the specified index at the start of a collection.|
|GetHashCode()||It return the hash code for the given instance.|
|GetOffset(Int32)||It is used to calculate the offset from the start of the collection using the given collection length.|
|ToString()||It is used to return the string representation of the current Index instance.|
