Why won't my "Delete an entry" section of code work?

I have tried this:

if (menuChoice == 4)

{

Console.WriteLine("Delete a Movie");

for (i = delete - 1; i < showTitles.Length; i++)

{

showTitles[i] = showTitles[i + 1];

}

Console.WriteLine("New List:");

for (i = 0; i < showTitles.Length; i++)

{ Console.WriteLine("Movies[" + (i + 1) + "]: " + showTitles[i]); showTitles[i] = Console.ReadLine();

} Console.WriteLine();

}

and:

else if (menuChoice == 4)

{

newShowTitles = new string[showTitles.Length - 1];

Console.WriteLine("Delete a Movie");

if (a < showTitles.Length)

{

if (a != (delete - 1))

{

newShowTitles[b] = showTitles[a];

b++;

}

a++;

}

for (int c = 0; c < newShowTitles.Length; c++)

{

showTitles[c] = newShowTitles[c];

}

num--;

}

Neither of these codes are able to do anything... When I get to this section all that comes up on the console is "Delete a Movie" and it goes back to the main menu.... Please help!!

Put a try catch around the code and a break point in the catch to see the exception.

Ideally showTitle would be a List not a string[].
if (delete >= 0 && delete < showTitles.Length)
{
   List<string> temp = showTitles.ToList();
   temp.RemoveAt(delete);
   showTitles = temp.ToArray();
}
else
{
   // invalid offset
}
