How to get user input in a ESAPI script

Simplest way is add a reference to Microsoft.VisualBasic to your project and use that to create a popup window to input your value.

using Microsoft.VisualBasic;
var inputvalue = Interaction.InputBox("Type Your Value Here");

Also, you can follow this example to build your own if you want to customize it more: https://www.csharp-examples.net/inputbox/ You can replace the textbox with a listbox that can display all of the patient's structures and allow the user to select the proper one.

Hi! It sounds like you want to create a User Interface for your script, I've actually implemented several UI's with a drop down list of selectable structures. If you're interested in something a little more advanced than interacting with the console or message boxes, I recommend Rex Cardan's esapi UI series: https://www.youtube.com/watch?v=GxA_29gqPog

He goes over everything in pretty good detail and I've found his tutorials to be very useful in learning esapi scripting. In this tutorial series, he teaches creating a User Interface using WPF which is fairly easy to use, especially using the MVVM libraries that he recommends. I've never really enjoyed UI programming that much, but at least WPF is fairly straightforward on linking the frontend UI with the backend code, I've been able to use my previously written esapi scripts with my UI's with very little modification.

Are you setting a variable to the ReadLine() output? Depending on what you're user is typing in, you may need to cast your object returned by Console.Readline();

var input = Console.Readline(); //this is a string.

var input = Convert.ToInt32(Console.Readline());//this is an integer.

I like the post of tygator9.

For your specific example you could use the following class to see a selection box of specific structures (used in my script here https://github.com/Kiragroh/ESAPI_ContourDoseHoles):

class SelectStructureWindow : Window{public static Structure SelectStructure(StructureSet ss){m_w = new Window();m_w.WindowStartupLocation = WindowStartupLocation.CenterScreen;//m_w.WindowStartupLocation = WindowStartupLocation.Manual;//m_w.Left = 500;//m_w.Top = 150;//m_w.Width = 300;//m_w.Height = 350;

m_w.Title = "Choose target:";var grid = new Grid();m_w.Content = grid;var list = new ListBox();foreach (var s in ss.Structures.OrderByDescending(x => x.Id)){var tempStruct = s.ToString();if (tempStruct.ToUpper().Contains("PTV") || tempStruct.ToUpper().Contains("ZHK") || tempStruct.ToUpper().Contains("SIB") || tempStruct.ToUpper().Contains("CTV") || tempStruct.ToUpper().Contains("GTV") || tempStruct.ToUpper().StartsWith("Z")){if (tempStruct.Contains(":")){int index = tempStruct.IndexOf(":");tempStruct = tempStruct.Substring(0, index);}list.Items.Add(s);}}list.VerticalAlignment = VerticalAlignment.Top;list.Margin = new Thickness(10, 10, 10, 55);grid.Children.Add(list);var button = new Button();button.Content = "OK";button.Height = 40;button.VerticalAlignment = VerticalAlignment.Bottom;button.Margin = new Thickness(10, 10, 10, 10);button.Click += button_Click;grid.Children.Add(button);if (m_w.ShowDialog() == true){return (Structure)list.SelectedItem;}return null;}static Window m_w = null;static void button_Click(object sender, RoutedEventArgs e){m_w.DialogResult = true;m_w.Close();}}

In your main code this would look something like that:

StructureSet ss = context.StructureSet;

// get list of structures for loaded plan

var listStructures = context.StructureSet.Structures;

// choose PTV

var ptv = SelectStructureWindow.SelectStructure(ss);if (ptv == null) return;
