C # Array methods for dynamically adding new elements

The split split operation of a string is often performed in development. Get the array and then do the corresponding thing!

Sometimes, however, the requirement determines that the length of the array is not fixed, and the C # array is not allowed to add new elements dynamically.

This thing let me also struggle for a long time!! The day after tomorrow also count the eyes of God! There's a way out!

How do I add an array dynamically? We're going to use List

Look at the following code:

string[] Ktcodes = new String[0]; Model comma split   list<string> ktls = Ktcodes.tolist ();  Ktls. ADD (Svktcode);     Ktcodes = Ktls. ToArray ();

This translates to the effect of adding new elements dynamically.
