I am completely new to c#, so please help me with the following problem.

I have an array list with some string elements.I want to edit/update a particular element at a particular index.

Can anyone please tell me a method, other than removing and then adding the edited element at the specific index?

Please find my try below[Changed the first element from "Black" to "Grey"]

ArrayList al = new ArrayList(){ "Black", "White", "Red"};

al.RemoveAt(0);

al.Insert(0,"Grey");

CodePudding user response：

Try this:

ArrayList al = new ArrayList(){ "Black", "White", "Red"};
al[0] = "Grey";

CodePudding user response：

The ArrayList type has an indexer you can use.

ArrayList al = new ArrayList { "Black", "White", "Red"};

al[0] = "Grey";
