Question

我正在使用EF6从模型第一次改为代码我首先从数据库选项中使用Code来生成我的类。

这些将与WPF应用程序一起使用。不幸的是，生成的项目没有ObservableCollections，也没有实现INotiftyPropertyChanged。

我想知道有没有办法自动化这个（通过改变c＃生成的类的行为，首先从DB选项中选择代码。否则我将不得不通过手工进行更改，这将是因为我们有100多张桌子，所以非常繁琐。

示例生成类（注意属性和类不实现INotiftyPropretyChanged，ICollections初始化为HashSets，当我们想要ObersvableCollections时），这些要求用于与WPF / XAML进行数据绑定原因：

{
    using System;
    using System.Collections.Generic;
    using System.ComponentModel.DataAnnotations;
    using System.ComponentModel.DataAnnotations.Schema;
    using System.Data.Entity.Spatial;

    [Table("TerminalSession")]
    public partial class TerminalSession
    {
        public TerminalSession()
        {
            TerminalCheckpoints = new HashSet<TerminalCheckpoint>();
            TerminalFloats = new HashSet<TerminalFloat>();
            TerminalTransactions = new HashSet<TerminalTransaction>();
        }

        public int TerminalSessionID { get; set; }

        public int? TerminalID { get; set; }

        public DateTime? StartDate { get; set; }

        public DateTime? EndDate { get; set; }

        public virtual ICollection<TerminalCheckpoint> TerminalCheckpoints { get; set; }

        public virtual ICollection<TerminalFloat> TerminalFloats { get; set; }

        public virtual ICollection<TerminalTransaction> TerminalTransactions { get; set; }
    }
}

我们真正想要的代码：

{
    using System;
    using System.Collections.Generic;
    using System.ComponentModel.DataAnnotations;
    using System.ComponentModel.DataAnnotations.Schema;
    using System.Data.Entity.Spatial;

    [Table("TerminalSession")]
    public partial class TerminalSession : INotifyPropertyChanged
    {
        private int _terminalSessionId;
        private int? _terminalId;
        private DateTime? _startDate;
        private DateTime? _endDate;

        public TerminalSession()
        {
            TerminalCheckpoints = new ObservableCollection<TerminalCheckpoint>();
            TerminalFloats = new ObservableCollection<TerminalFloat>();
            TerminalTransactions = new ObservableCollection<TerminalTransaction>();
        }

        public int TerminalSessionID
        {
            get { return _terminalSessionId; }
            set
            {
                if (value == _terminalSessionId) return;
                _terminalSessionId = value;
                OnPropertyChanged();
                _terminalSessionId = value;
            }
        }

        public int? TerminalID
        {
            get { return _terminalId; }
            set
            {
                if (value == _terminalId) return;
                _terminalId = value;
                OnPropertyChanged();
                _terminalId = value;
            }
        }

        public DateTime? StartDate
        {
            get { return _startDate; }
            set
            {
                if (value == _startDate) return;
                _startDate = value;
                OnPropertyChanged();
                _startDate = value;
            }
        }

        public DateTime? EndDate
        {
            get { return _endDate; }
            set
            {
                if (value == _endDate) return;
                _endDate = value;
                OnPropertyChanged();
                _endDate = value;
            }
        }

        public virtual ObservableCollection<TerminalCheckpoint> TerminalCheckpoints { get; set; }

        public virtual ObservableCollection<TerminalFloat> TerminalFloats { get; set; }

        public virtual ObservableCollection<TerminalTransaction> TerminalTransactions { get; set; }
        public event PropertyChangedEventHandler PropertyChanged;

        [NotifyPropertyChangedInvocator]
        protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
        {
            PropertyChangedEventHandler handler = PropertyChanged;
            if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));

        }
    }
}

选项我在visual studio中选择。 enter image description here
