详解C#中一维数组的插入
一维数组的插入:
实现效果:在1 2 3 后面插入4

namespace Array
{
class Program
{
static void Main(string[] args)
{
int[] array = new int[] { 1, 2, 3 };
int[] des = addArray(array, 4, 4);
foreach (int item in des)
{
Console.WriteLine(item );
}
Console.ReadLine();
}
static int[] addArray(int[] bornArray, int index, int value)
{
ArrayList list = new ArrayList(bornArray );
if (index <0)
{
index =0 ;
}
if (index >bornArray .Length -1)
{
index = bornArray.Length;
}
list.Insert(index ,value );
int[] des = new int[list.Count ];
for (int i=0;i<list.Count;i++)
{
des[i] = (int)list[i];
}
return des;
}
}
}
