WPF combobox

先写一个数据类Grade.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Collections.ObjectModel;

namespace ImgProWPF

{

    public class Grade

    {

        public string Name { set; get; }

    }

    public class GradeAdd:ObservableCollection<Grade>

    {

        public GradeAdd()

        {

            this.Add(new Grade { Name = "0" });

            this.Add(new Grade { Name = "0.5" });

            this.Add(new Grade { Name = "1" });

            this.Add(new Grade { Name = "2" });

            this.Add(new Grade { Name = "3" });

            this.Add(new Grade { Name = "4" });

            this.Add(new Grade { Name = "5" });

        }

    }

}

在MainWindow.xaml里调用

xmlns:local="clr-namespace:ImgProWPF"

 <Grid.Resources>

       <local:GradeAdd x:Key="grade"/>

 </Grid.Resources>

<ComboBox x:Name="comPersonalGrade" Grid.Column="1" Grid.Row="12" SelectedItem="0" ItemsSource="{StaticResource grade}" DisplayMemberPath="Name"/>

以上为绑定里数据，可以看到内容

下面为获得选中的内容

            Grade gradeP = (Grade)comPersonalGrade.SelectedItem;

            string gradep = gradeP.Name.ToString();
