ComboBox.SelectedItem

写一个类:

    public class ActivityDto
    {

        private string name;
        private string value;
        private string para;

        public string Name
        {

            get { return name; }
            set { name = value; }
        }

        public string Value
        {

            get { return value; }
            set { this.value = value; }
        }

        public string Para
        {

            get { return para; }
            set { para = value; }
        }
    }

给一个ComboBox绑定值：

            List<ActivityDto> dtolist=List<ActivityDto>();

            dtolist.AddRange(..);

            cboActivity.DataSource=dtolist

            cboActivity.DisplayMember = “Name”;
            cboActivity.ValueMember = “Value”;
            cboActivity.SelectedIndex = 0;

取值：

        ActivityDto dto = cboActivity.SelectedItem as ActivityDto;
