using System.Windows; using System.Windows.Controls; namespace YourNamespace { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } private void OpenPopup_Click(object sender, RoutedEventArgs e) { // Create a new popup window PopupWindow popup = new PopupWindow(); if (popup.ShowDialog() == true) { // Get the user's input from the popup string userName = popup.UserName; MessageBox.Show($"Hello, {userName}!"); } } } } using System.Windows; namespace YourNamespace { public partial class PopupWindow : Window { public string UserName { get; private set; } public PopupWindow() { InitializeComponent(); } private void OkButton_Click(object sender, RoutedEventArgs e) { UserName = txtUserName.Text; DialogResult = true; } private void CancelButton_Click(object sender, RoutedEventArgs e) { DialogResult = false; } } }

Create a new WPF Window in your project. You can name it something like "NameInputDialog.xaml". Design the window with a TextBox for the user to input their name and a couple of buttons (e.g., "OK" and "Cancel"). In the code-behind of the window ("NameInputDialog.xaml.cs"), create a property to store the user's input name: public partial class NameInputDialog : Window { public string UserName { get; private set; } public NameInputDialog() { InitializeComponent(); } private void OkButton_Click(object sender, RoutedEventArgs e) { UserName = NameTextBox.Text; DialogResult = true; } private void CancelButton_Click(object sender, RoutedEventArgs e) { DialogResult = false; } } When you want to show the input dialog to the user, create an instance of the custom window and display it modally: NameInputDialog dialog = new NameInputDialog(); if (dialog.ShowDialog() == true) { string userName = dialog.UserName; // Use the userName variable for further processing } Using MessageBox for Simplicity: You can use the MessageBox class to get a simple input from the user, but this approach doesn't allow as much customization as a custom window. string userName = Microsoft.VisualBasic.Interaction.InputBox("Enter your name:", "Name Input", ""); if (!string.IsNullOrEmpty(userName)) { // Use the userName variable for further processing }
