Editing an item in a list

November 22, 2023 by Tarik

After adding an item to a list, you can replace it by writing

list[someIndex] = new MyClass();

You can modify an existing item in the list by writing

list[someIndex].SomeProperty = someValue;

EDIT: You can write

var index = list.FindIndex(c => c.Number == someTextBox.Text);
list[index] = new SomeClass(...);
