I found a VB version of this here, but I'd like to use a Lambda Expression to take a List of strings and then prepend a string onto every item in the list. 

It seems like using the ForEach ends up sending in the string by value, so any changes disappear. Here's the line of code I was hoping to have work.

```
listOfStrings.ForEach((listItem) => {listItem = listItem.Insert(0,"a");});

```
