Array  is a collection of similar data type . It contains the fixed length with same data type. int [] arr= new int [10]; // One dimension Here the int array contains the 10 item, item starting from 0 to 9. Array indexing  is start with zero (0th- position) and the last position is total minus one (Total no of array -1).  But dynamic array not have predefined size. It dynamically manages the size when you add the item in the list. Types of Arrays One-dimensional Arrays  Two-dimensional Arrays  Jagged Arrays  Mixed Arrays  1. One-dimensional Arrays double [] doubleArray = new double [15]; char [] charArr = new char [15]; bool [] boolArr = new bool [20]; string [] stringArr = new string [100]; Array Properties IsFixedSize => Return a value indicating if an array has a fixed size or not.  IsReadOnly => Return a value indicating if an array is read-only or not.  LongLength ...
