I am trying to delete an element from an array. I have an array of 52
elements and I want to search for an element and delete it. Therefore,
making it an array of 51 elements.

is it just

delete MyArray;


any help would be great....thanks

Arrays have a fixed size you set when you allocate them so you canät
do that. You may want to use an ArrayList instead.

Change to an ArrayList or similar (SortedList) as arrays are initialized to
a specific size and do not automagically resize because you are tired of one
item.

Once you get onto the latest release containing generics, there is a static
method on the Array class called Resize---

int[] myArray = new int[10];

// populate it

int[] myShorterArray = Array.Resize<int>(9);

// you have just truncated the array by one element.

Now, if you read carefully, all this is really doing is re-allocating the
array and copying the appropriate elements into the new array. this is the
same manual process you could have done pre-generics, but this makes it so
much cleaner.

Not to disagree with the other replies- this is just one more way of looking
at it.
