Question

I have a foreach loop that I need to pause in order to allow user input on the form.

foreach (XmlNode node2 in xmlFile)
   {
       ...get currentRow from XML file
       ...update form label

       ???wait for user to enter data on form and press button
   }

Is there any sort of wait-for-user-input function in C# that I can use to do this?

UPDATE:

Based on the feedback I have successfully modified the program to:

• Load the XML list into a Queue (using the ForEach loop)
• Setup the user input to iterate through the Queue (remove top item, show next top item)

Answer 1

You can open a modal form where the user can make the input.

If you want to stay on the same form all the time you better copy all nodes to an Queue<XmlNode>, process one at a time and when the user presses the button pick the next item in the Queue until the queue is empty.
