varmyArray = Array.Empty<string>(); This method is concise and performs well. It creates an empty array with zero elements, without the overhead of allocating memory for a new array with a length of 0. In addition,it is also very readable and conveys the intention of creating an empty ...
Declare a char array and set the size − char[] arr = new char[5]; Now set the elements − arr[0] = 'h'; arr[1] = 'a'; arr[2] = 'n'; arr[3] = 'k'; arr[4] = 's'; Let us see the complete code now to declare, initialize and display char arrays in C# − ...
