wpf多界面传输数据

以wpf为前台 c#为后台
我在界面一的后台计算出数据aa，bb
希望在界面二展示
求运用c#中的类来解决

看你问了几次了

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ComponentModel;

namespace WpfApplication1
{
    class Dataabb:INotifyPropertyChanged
    {
        protected void ech<T>(ref T propValue, T newValue, string propName = "");

        int m_aa;
        public int aa
        {
            get { return m_aa; }
            set
            {
                ech(ref m_aa, value);
            }
        }

        int m_bb;
        public int bb
        {
            get { return m_bb; }
            set
            {
                ech(ref m_bb, value);
            }
        }
    }
}

界面2定义一个公共变量,打开界面2的时候把界面1的值赋值给这个变量，就获取到界面1的值了。

更详细供参考

Dataabb数据模型

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ComponentModel;

using System.Runtime.CompilerServices;


namespace WpfApplication1
{
    public class Dataabb:INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;

        protected void ech<T>(ref T propValue, T newValue, [CallerMemberName] string propName = "")
        {
            if (object.Equals(propValue, newValue)) return;

            propValue = newValue;
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(propName));
            }
        }

        int m_aa;
        public int aa
        {
            get { return m_aa; }
            set
            {
                ech(ref m_aa, value);
            }
        }

        int m_bb;
        public int bb
        {
            get { return m_bb; }
            set
            {
                ech(ref m_bb, value);
            }
        }
    }
}

Window1代码


    public partial class Window1 : Window
    {
        public Dataabb dataabb = new Dataabb();
        public Window1()
        {
            InitializeComponent();
            dataabb.aa = 34;
            dataabb.bb = 55;
            Binding bdaa = new Binding() { Path = new PropertyPath("aa"), Source = dataabb };
            textBox1.SetBinding(TextBox.TextProperty, bdaa);
            textBox3.SetBinding(TextBox.TextProperty, bdaa);

            Window2 win2 = new Window2();
            win2.textBox1.SetBinding(TextBox.TextProperty, bdaa);

            Binding bdbb = new Binding() { Path = new PropertyPath("bb"), Source = dataabb };
            textBox2.SetBinding(TextBox.TextProperty, bdbb);
            win2.textBox2.SetBinding(TextBox.TextProperty, bdbb);

            win2.Show();
        }
    }

运行效果
