C# Splitting An Array

Question

I need to split an array of indeterminate size, at the midpoint, into two separate arrays.

The array is generated from a list of strings using ToArray().

        public void AddToList ()         {             bool loop = true;             string a = "";              Console.WriteLine("Enter a string value and press enter to add it to the list");             while (loop == true)             {                 a = Console.ReadLine();                  if (a != "")                 {                     mylist.Add(a);                 }                 else                 {                     loop = false;                 }             }          }          public void ReturnList()         {             string x = "";             foreach (string number in mylist)             {                 x = x + number + " ";             }             Console.WriteLine(x);             Console.ReadLine();         }      }      class SplitList     {         public string[] sTop;         public string[] sBottom;          public void Split(ref UList list)           {             string[] s = list.mylist.ToArray();              //split the array into top and bottom halfs          }     }      static void Main(string[] args)     {         UList list = new UList();         SplitList split = new SplitList();          list.AddToList();         list.ReturnList();          split.Split(ref list);     } } 

}

Answer 1

You could use the following method to split an array into 2 separate arrays

public void Split<T>(T[] array, int index, out T[] first, out T[] second) {   first = array.Take(index).ToArray();   second = array.Skip(index).ToArray(); }  public void SplitMidPoint<T>(T[] array, out T[] first, out T[] second) {   Split(array, array.Length / 2, out first, out second); } 

Answer 2

Use a generic split method:

public static void Split<T>(T[] source, int index, out T[] first, out T[] last) {     int len2 = source.Length - index;     first = new T[index];     last = new T[len2];     Array.Copy(source, 0, first, 0, index);     Array.Copy(source, index, last, 0, len2); }
