title: Populate ListBox using a database in C#
body: <p>I have been working with a local database using C# windows forms.  I wanted to know how to populate a listBox (or basically retrieve any particular piece of info from the DB and set it to a variable).  It seems obvious that I would need to use a query to gather a particular piece of info, but i dont know how to do this. </p>
  
  <p>Example:  Person Table has the following columns - ID, FirstName, LastName, Age</p>
  
  <p>How do I populate a ListBox with each persons First Name in the Database? </p>
  
  <p>Kind of like <code>listBox1.Items.Add(Query: Select FirstName from Person)</code>
  or <code>string variable1 = (Query: SelectFirstName from Person Where ID = 1);</code></p>
