Add item to array []

Question

I have a class that has a string string [] property.

I need to create another element of the array, do I need to reset the size and copy all the previous elements?

Answer 1

You can use Array.Resizethat will save the contents of the array.

eg.

var array = myClass.SomeArrayProperty;
Array.Resize(ref array, newSize);
myClass.SomeArrayProperty = array;

You need to use a temporary variable because properties cannot be used as arguments ref.
