here's my refactored version which accepts multiline/single as an option

   public string ShowDialog(string text, string caption, bool isMultiline = false, int formWidth = 300, int formHeight = 200)
        {
            var prompt = new Form
            {
                Width = formWidth,
                Height = isMultiline ? formHeight : formHeight - 70,
                FormBorderStyle = isMultiline ? FormBorderStyle.Sizable : FormBorderStyle.FixedSingle,
                Text = caption,
                StartPosition = FormStartPosition.CenterScreen,
                MaximizeBox = isMultiline
            };

            var textLabel = new Label
            {
                Left = 10,
                Padding = new Padding(0, 3, 0, 0),
                Text = text,
                Dock = DockStyle.Top
            };

            var textBox = new TextBox
            {
                Left = isMultiline ? 50 : 4,
                Top = isMultiline ? 50 : textLabel.Height + 4,
                Multiline = isMultiline,
                Dock = isMultiline ? DockStyle.Fill : DockStyle.None,
                Width = prompt.Width - 24,
                Anchor = isMultiline ? AnchorStyles.Left | AnchorStyles.Top : AnchorStyles.Left | AnchorStyles.Right
            };

            var confirmationButton = new Button
            {
                Text = @"OK",
                Cursor = Cursors.Hand,
                DialogResult = DialogResult.OK,
                Dock = DockStyle.Bottom,
            };

            confirmationButton.Click += (sender, e) =>
            {
                prompt.Close();
            };

            prompt.Controls.Add(textBox);
            prompt.Controls.Add(confirmationButton);
            prompt.Controls.Add(textLabel);

            return prompt.ShowDialog() == DialogResult.OK ? textBox.Text : string.Empty;
        }
