Editing a field in a DataRow

Hi.

When working on an application connected to a database I stumbled upon a question which I can't seem to find an answer for searching the Web.
Which of the following two ways are to prefer when editing fields in a DataRow, and why?
If it's of any concern I'm NOT using LINQ to retrieve the DataRow.

This:

Code:

---

DataRow dr = ...
string myValue = "...";

dr["myField"] = myValue;
myValue = (string)dr["myField"];

---

Or this:

Code:

---

DataRow dr = ...
string myValue = "...";

dr.SetField<string>("myField", myValue);
myValue = dr.Field<string>("myField");

---

Michael
