title: Taking user input from a textbox to create a text file name
body: <p>I am using Visual Studio 2013 and C#</p>
  
  <p>I currently have a form which, among other items, has a textbox for the user to enter an id number. I want to be able to 'take' this number and create a text file with the ID number as a file name.</p>
  
  <p>I have been able to write to a file using the OpenFileDialog and Streamwriter, but this requires the user to click the "Save Location" button and browse to a file location, then enter the text for the file they want created.</p>
  
  <p>I would rather have the program create the .txt file based on the id number so that they can just enter their ID and then press enter to start the program.</p>
  
  <p>Is this possible?</p>
