C# Incrementing a String Array

Question

Hi everyone, is there a way to increment a string array? Every time the MoveUpOne button is pressed I want someString to increment to the next element of the string Array.Can that be done?

 public String someString;
 public String[] someArray;
 
 void Start(){
 someString = someArray[0];
 someArray = new string[]{"text","text2","text3"};
 }
 void OnGUI(){
 if (GUILayout.Button("MoveUpOne", GUILayout.Width(50), GUILayout.Height(25))){
 //Make someString increment from someArray[0] to someArray[1] and so on
   }
 }

Keep a separate variable that stores the current index into someArray. Increment that variable, then set someString to the array value at that index.

 int someStringIndex;

 void OnGUI()
 {
   if (GUILayout.Button("MoveUpOne", GUILayout.Width(50), GUILayout.Height(25)))
   {
     someStringIndex++;
     someString = someArray[someStringIndex];
   }
 }

You will need to make sure someStringIndex doesn't go beyond the end of the array.
