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

Question

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!!
