如何从该属性的 getter/setter 中获取属性名称? [英] How to get property name from within getter/setter of that property?

问题描述

假设我们有如下属性

public string SomeProperty
{
    get
    {
        var propName = "SomeProperty";
        return "<" + propName + ">";
    }
}

如何通过读取程序集信息本身将上述变量 propName 的值设置为属性名称?

How can I set value of the above variable propName to be the property name by reading from the assembly information itself?

我们为什么需要这个?

我正在使用 此处 这将帮助我显示绑定属性的设计模式"值 - 通常是绑定值在设计模式下显示为空字符串.在设计模式"数据上下文类中，我想为我可能拥有的每个绑定属性返回属性名称.

I'm using the WPF d:DataContext as mentioned in here which will help me to display a 'design-mode' value for bound properties - very often, the bound values are displayed as empty string in design mode. And in the 'design-mode' data-context class, I want to return the property name for every binding properties I may have.

希望这能解释您的担忧.

推荐答案

过了一会儿，我想出了一个如下的解决方案，对我来说很方便.

After a while I figure out a solution as below, which is quite convenient to me.

    string SomeProperty
    {
        get
        {
            return GetDesignModeValue(() => this.SomeProperty);
        }
    }

    string GetDesignModeValue<T>(Expression<Func<T>> propertyExpression)
    {
        var propName = (propertyExpression.Body as MemberExpression).Member.Name;
        var value = string.Format(
            "<{0}>"
            , propName);
        return value;
    }

因此，从现在开始，我们在设计模式下显示绑定属性的 mocking 值要容易得多.

So, from now on, it is much much easier for us to show the binding properties' mocking value when in design mode.

我希望有一天你会发现它有帮助！
