How do assign a value(string) from database to textbox

My issue is im trying to write a lambda expression! Problem is that I am not sure I am doing it right.

var result = dataset.student.Where(n => n.ID == num);
**num is a value recieved from id text box


var result stores my object pulled from database (which is a person), so now i need to assign the textbox "FirstNameTxtBox" with result FirstName

this.FirstNameTextBox = result.Where(n=>n.FirstName);


this is where I am failing as my expression keeps out "cannot convert String to bool. To be honest not sure if it is the right expression.
Hope this is clear.

It should be:

this.FirstNameTextBox.Text = result.Select(n => n.FirstName).FirstOrDefault();
