Question

我正在使用C＃中的数据绑定编写winforms应用程序。我最近发现我写了很多属性，如下面的代码所示。编写这些代码是可以的，但我想也许我会错过一些东西，也许我可以编写更少代码并使代码看起来更干净？

这样做是否有自动化方式？
像Codedom或我不知道的任何框架？

public class SampleClass : INotifyPropertyChanged
{
    public Boolean Enabled
    {
        get { return _enabled; }
        set
        {
            if (_enabled == value) return;

            _enabled = value;

            // broadcast the change
            RaisePropertyChanged(PropertyName_Enabled);

            // this object is modified
            this.Modified = true;
        }
    }

    public Single Degree
    {
        get { return _degree; }
        set
        {
            if (_degree == value) return;

            _degree = value;

            // broadcast the change
            RaisePropertyChanged(PropertyName_Degree);

            // this object is modified
            this.Modified = true;
        }
    }

    // Define the property name this class exposes and notifies
    public static readonly String PropertyName_Enabled = "Enabled";
    public static readonly String PropertyName_Degree = "Degree";

    private Boolean _enabled;
    private Single _degree;    
}

只需创建一个code snippet：

（这与您展示的代码不完全相同，但您可以轻松地根据您的具体需求进行调整）

不可否认，代码看起来不会更清晰，但至少你会花更少的时间来编写代码;）

有没有办法为我的类自动生成那些数据绑定就绪属性？
