WPF CollectionView 의 SortDescriptions 를 이용해 데이터 정렬하기

 

CollectionView 의 SortDescriptions 를 데이터 정렬 기능을 알아봅니다.

Person.cs

using System.ComponentModel;
 
namespace WpfApp
{
    public class Person : INotifyPropertyChanged
    {
        /// <summary>
        /// 속성변경 이벤트입니다.
        /// </summary>
        public event PropertyChangedEventHandler PropertyChanged;
 
        /// <summary>
        /// 이름입니다.
        /// </summary>
        string name = "";
 
        /// <summary>
        /// 별명입니다.
        /// </summary>
        string nickName = "";
 
        /// <summary>
        /// 이름입니다.
        /// </summary>
        public string Name
        {
            set
            {
                this.name = value;
                OnPropertyChanged(nameof(Name));
            }
            get { return name; }
        }
 
        /// <summary>
        /// 별명입니다.
        /// </summary>
        public string NickName
        {
            set
            {
                nickName = value;
                OnPropertyChanged(nameof(NickName));
            }
            get { return nickName; }
        }
 
        /// <summary>
        /// 속성 값이 변경될 때 발생합니다.
        /// </summary>
        /// <param name="propertyName"></param>
        protected virtual void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }
}
