wpf代码实现绑定数据

 listview:

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            Models.kuContext ku = new Models.kuContext();

            ((GridView)_list.View).Columns[0].DisplayMemberBinding = new Binding { Path = new PropertyPath(nameof(Models.Warehouse.Name)) };
            ((GridView)_list.View).Columns[1].DisplayMemberBinding = new Binding { Path = new PropertyPath(nameof(Models.Warehouse.Classify)), Converter = new Classify() };
            ((GridView)_list.View).Columns[2].DisplayMemberBinding = new Binding { Path = new PropertyPath(nameof(Models.Warehouse.State)), Converter = new Status() };
            ((GridView)_list.View).Columns[3].DisplayMemberBinding = new Binding { Path = new PropertyPath(nameof(Models.Warehouse.Region)), Converter = new Region() };
            ((GridView)_list.View).Columns[4].DisplayMemberBinding = new Binding { Path = new PropertyPath(nameof(Models.Warehouse.Direction)) };

            ((GridView)_list.View).Columns[9].DisplayMemberBinding = new Binding { Path = new PropertyPath(nameof(Models.Warehouse.PositionY)) };
            _list.ItemsSource = r;
        }
        private class Region : IValueConverter
        {
            public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
            {
                Models.kuContext k = new Models.kuContext();
                int id = (int)value;

                if (c != null)
                {
                    return c.Name;
                }
                return "";
            }

            public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
            {
                throw new NotImplementedException();
            }
        }

 textbox:

        t1 t = new t1 { a="1",b="2"};
        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            
            tb.SetBinding(TextBox.TextProperty, new Binding { Path = new PropertyPath("a") });//lable    l1.SetBinding(Label.ContentProperty, ("FilePath"));

        }

            public string b { get { return _b; } set { _b = value; OnPropertyChanged(new PropertyChangedEventArgs("b")); } }

            public event PropertyChangedEventHandler PropertyChanged;
            public void OnPropertyChanged(PropertyChangedEventArgs e)
            {
                if (PropertyChanged != null)
                {
                    PropertyChanged(this, e);
                }
            }
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {

        }

        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            var aa = t;
        }
//第二种写法
class Bean : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;                   //属性改变时触发的事件
        private string filePath;                                                    //文件路径名

        {
            get
            {
                return this.filePath;
            }
            set
            {
                if (this.filePath != value)           //如果当前的变量值不等于先前的文件名，说明需要更新文件名
                {
                    this.filePath = value;                                          //更新文件名

                    {
                        //通知绑定此变量的textbox在前台更新
                        PropertyChanged(this, new PropertyChangedEventArgs("FilePath"));
                    }
                }
            }
        }
    }

combobox/listbox:

            BindingList<Models.NameValue<string>> csex = new BindingList<Models.NameValue<string>>();
            foreach (var item in Enum.GetNames(typeof(Models.CustomerSex)))
            {
                csex.Add(new Models.NameValue<string> { Name = item, Value = item });
            }
            s1_c_sex.ItemsSource = csex;
            s1_c_sex.DisplayMemberPath = "Name";
            s1_c_sex.SelectedValuePath = "Value";
