Hi everyone!
I have a question about a topic of WPF and C#

In my project have the following controls:
http://subirimagen.me/uploads/20180529170428.PNG

I need get serial number of the database of SQL when I press the Search button, but this should be identical to name of the textbox of user. In this project I use Entity Framework 6.

In SQL the query is similar to:
select serial_number from dbo
where [txtUser] == name_user

Could explain me a method for this case?

What I have tried:

Try search some methods but not work in my project.

You can use LINQ

var filteredData = db.SerialNumbers
                     .Where(x => x.serial_number.Contains(this.FilterTextBox.Text));
