＆＃39; EmployeeDetails＆＃39;没有实现接口成员＆＃39; System.ComponentModel.INotifyPropertyChanged.PropertyChanged＆＃39;

Question

我正在尝试实现Inotifypropertychange接口，例如

public class EmployeeDetails:INotifyPropertyChanged
{
 private int employeeID;
    public int EmployeeID
    {
        get { return employeeID; }
        set { employeeID = value; this.NotifyPropertyChanged("EmployeeId"); }
    }

    private string employeeName;
    public string EmployeeName
    {
        get { return employeeName; }
        set { employeeName = value; this.NotifyPropertyChanged("EmployeeName"); }
    }

    private decimal salary;
    public decimal Salary
    {
        get { return salary; }
        set { salary = value; this.NotifyPropertyChanged("Salary"); }
    }
    public event PropertyChangedEventHandler propertychange;

    public void NotifyPropertyChanged(string name)
    {
        if (propertychange != null)
            propertychange(this, new PropertyChangedEventArgs(name));
    }
    public EmployeeDetails(int employeeId, string employeeName, decimal salary)
    {
        EmployeeID = employeeID;
        EmployeeName = employeeName;
        Salary = salary;
    }

    public EmployeeDetails()
    {
        // TODO: Complete member initialization
    }

}

在调试时，它显示以下错误：

'EmployeeDetails'未实现接口成员'System.ComponentModel.INotifyPropertyChange

我遗漏了哪些特定代码，请帮忙 我已经加入了system.component汇编。

Answer 1

您可以使用此代码

public class EmployeeDetails : INotifyPropertyChanged
{
  ...
}

右键单击INotifyPropertyChanged，首先执行resolve reference并选择实现接口
