如何获取对象属性的默认值? [英] How to get the default value of an object property?

问题描述

一些代码:

foreach (System.Reflection.PropertyInfo pi in myObject.GetType().GetProperties())
{
    if (pi.CanWrite)
    {
        object value = pi.GetValue(Properties, null);

        // if (value is not default)
        // {
        X.addAttribute(pi.Name, value);
        // }
    }
}

如果该属性位于其DefaultValue，我想做的就是不调用'X.addAttribute ...'行.我认为可以通过某种方式获取属性的DefaultValue，以便进行比较?

What I'm trying to do is not-call the line 'X.addAttribute...' if the property is at its DefaultValue. I assume there's some way of getting the DefaultValue of a property so I can do a comparison?

出于我的目的，我试图获取DefaultValueAttribute定义的默认"值.

For my purpose I am trying to get the 'default' value as defined by DefaultValueAttribute.

我们非常感谢您的帮助，

Any help is appreciated, cheers.

推荐答案

假设您要获取DefaultValue属性，请在PropertyInfo对象上使用GetCustomAttributes.

Assuming you're trying to get the DefaultValue attribute, use GetCustomAttributes on your PropertyInfo objects.
