How to remove an element from an regular array in C#?
Well, you can’t really change a regular array or remove an item from it. You have to create a new array that is a copy of the current array without the one value you want.
Here is a quick static class I created that will copy your array, leaving out the one item you don’t want.
namespace ArrayItemDeleter
{
static class ArrayItemDeleter
{
public static void RemoteArrayItem
{
T[] newArray = new T[inArray.Length – 1];
for (int i = 0, j = 0; i < newArray.Length; i++, j++)
{
if (i == inIndex)
{
j++;
}
newArray[i] = inArray[j];
}
inArray = newArray;
}
}
}

Here is how you would use it in your program.
[sourcecode language="csharp"]
using System;
namespace ArrayItemDeleter
{
class Program
{
static void Main(string[] args)
{
string[] str = {"1","2","3","4","5"};
ArrayItemDeleter.RemoteArrayItem(ref str, 2);
}
}
}
[/sourcecode]
Now, if you really want to add and remove items a lot, you should use a System.Collections.Generic.List object;
