arrays are immutable. You can't delete elements from them without making new arrays.

oh alright so when i do an array that has like 10 different values, its size will always be 10 no matter what ?

You can use Array.Resize to change the size of an existing array. That method will internally make a new array with the desired size and copy the data from the old array into it. Generally, however, if you want an array-like instance that you can grow and shrink, you should use a List<T> and not an array.
