 There is a pre-defined class called “Array”.
 C# recognizes every array as an object for the “System.Array” class.
 As an advantage of this, every array can access the members for that “Array” class.
 For common programming needs, the “Array” class offers few properties and few methods, which are useful for general manipulations of arrays.
 Here, you can see the available properties of “array” class in this table:
Properties of “Array” Class

Property	Description
Length	Gets the array size (total no. of elements in the array)
Rank	Gets the no. of dimensions of the array

Syntax to access the property: arrayname.Property

---

 Copying arrays:
Syn: arrayname.CopyTo(DestinationArray, StartIndex);
Ex: a.CopyTo(b, 0);
Note: The size and dimensions of both a and b arrays, should be same. It copies all the elements into the destination array.

 Sorting arrays:
Syn: Array.Sort(arrayname);
Ex: Array.Sort(a);
Note: “Sort” is a static method of “Array” class. It sorts all the array elements in ascending order.

 Reversing arrays:
Syn: Array.Reverse(arrayname);
Ex: Array.Reverse(a);
Note: “Reverse” is a static method of “Array” class. It exactly reverses the all the array elements.

 Searching arrays for an element:
Syn: Array.IndexOf(arrayname, value);
Ex: Array.IndexOf(a, 50);
Note: “IndexOf” is a static method of “Array” class. It searches the array for the given value, and returns it’s index if it is found; otherwise, it returns -1;
