How do I concatenate two arrays in C#?
You could write an extension method:
public static T[] Concat<T>(this T[] x, T[] y){ if (x == null) throw new ArgumentNullException("x"); if (y == null) throw new ArgumentNullException("y"); int oldLen = x.Length; Array.Resize<T>(ref x, x.Length + y.Length); Array.Copy(y, 0, x, oldLen, y.Length); return x;}Then:
int[] x = {1,2,3}, y = {4,5};int[] z = x.Concat(y); // {1,2,3,4,5}
