Is it possible to resize an array in C#
You cannot resize an array in C#, but using Array.Resize you can replace the array with a new array of different size.
The following is our array −
char[] ch = new char[10]; ch[0] = 'a'; ch[1] = 'b';
Now, resize −
Array.Resize<char>(ref ch, 10);
The following is the complete example −
Example
using System;
class Program {
static void Main() {
char[] ch = new char[10];
ch[0] = 'a';
ch[1] = 'b';
// Resize array
Array.Resize<char>(ref ch, 10);
// Set value for new elements
ch[2] = 'c';
ch[3] = 'd';
ch[4] = 'e';
ch[5] = 'f';
ch[6] = 'g';
ch[7] = 'h';
ch[8] = 'i';
ch[9] = 'j';
Console.WriteLine("New Array: "+ new string(ch));
}
}Output
New Array: abcdefghij
