C# 如何将输入按钮逻辑添加到文本框

我有下面的WPF视图，用户在其中输入三个字段的信息，以便保存它们，然后按下“OK”按钮。添加逻辑的最佳方法是什么？用户也可以在任何文本框上按enter键，然后按enter键，它将绑定到我的OKButton命令/逻辑

XAML.CS

namespace Pandai.Application.Framework.View
{
    public partial class PopupLockDatabaseView : Window
    {
        public PopupLockDatabaseViewModel model;
        public PopupLockDatabaseView()
        {
            InitializeComponent();
            this.Loaded += OnClose;
            txtFor.Focus();
        }



        void OnClose(object sender, RoutedEventArgs e)
        {
            model = (PopupLockDatabaseViewModel)this.DataContext;
            model.View = this;

        }

    }
}

您可以将按钮的属性设置为True，使其成为接受按钮

            //MessageBox.Show("Please Logout and log back in.");

            View.Close();

        }
