System.ArrayCopyTo() vs System.ArrayClone() in C#
The ArrayCopyTo() method copies all the elements of the current one-dimensional Array to the specified one-dimensional Array starting at the specified destination Array index. The index is specified as a 32-bit integer.
The CopyTo() method in C# is used to copy elements of one array to another array. In this method, you can set the starting index from where you want to copy from the source array.
The following is an example showing the usage of CopyTo(,) method of array class in C# −
Example
using System;
class Program {
static void Main() {
int[] arrSource = new int[4];
arrSource[0] = 5;
arrSource[1] = 9;
arrSource[2] = 1;
arrSource[3] = 3;
int[] arrTarget = new int[4];
// CopyTo() method
arrSource.CopyTo(arrTarget,0 );
Console.WriteLine("Destination Array ...");
foreach (int value in arrTarget) {
Console.WriteLine(value);
}
}
}Array.Clone() method in C# clones the array. Here, we have a string array −
Example
using System;
class Program {
static void Main() {
string[] arr = { "one", "two", "three", "four", "five" };
string[] arrCloned = arr.Clone() as string[];
Console.WriteLine(string.Join(",", arr));
// cloned array
Console.WriteLine(string.Join(",", arrCloned));
Console.WriteLine();
}
}
