Comparing two lists of names

I am trying to create a short Windows Presentation Foundation application in C# to compare two lists in different formats and output the users that are common to them.

Right now I am taking each list from the user via a textbox.

Now I am a little confused on how I can compare the two different textboxes and output the common names. If the data was in an array of some sort I could have used:

var name = string.Split('(')[0].Trim()

But since I decided to use textboxes, I am unsure of how to proceed with this. For example, consider the following two input lists and the expected output:

First List:

Jacqueline Beaurivage (loh Da road); 
Bon Van Daht (fary goal lim)
Bon Jobi (ting wei)
Ting Wan (dehtee road);

Second List:

Jacqueline Beaurivage
Bon Van Daht

Expected output:

Jacqueline Beaurivage
Bon Van Daht

var commonNames = firstList
                    .Select(m => m.Split('(')[0].Trim())
                    .Intersect(secondList);

with TextBoxes, as pointed by Austin Salonen

var firstList = textBox1.Text.Select(m => m.Split(Environment.NewLine));

var secondList = textBox2.Text.Select(m => m.Split(Environment.NewLine));

resultTextBox.Text = string.Join(Environment.NewLine,
                           firstList
                             .Select(m => m.Split('(')[0].Trim())
                             .Intersect(secondList));
