C#属性数组 [英] C# array of properties

问题描述

我有几个get属性，它们希望像函数数组一样循环遍历.我希望能够做这样的事情

I have several get properties that I would like to be able to loop through like an array of functions. I would like to be able to do something like this

public int prop1 { get; }
public string prop2 { get; }
public int[] prop3 { get; }
public int prop4 { get; }
public string prop5 { get; }
public string prop6 { get; }

Func<var> myProperties = { prop1, prop2, prop3, prop4, prop5, prop6 };

ArrayList myList = new ArrayList();
foreach( var p in myProperties)
{
    myList.Add(p);
}

这段代码很破损，但是我认为它传达了我想要做的事情的想法.有人知道我该怎么做到吗?

This code is very broken, but I think it conveys the idea of what I would like to be able to do. Anyone know how I can achieve this?

推荐答案

您可以使用反射来访问您类型中的属性:

You could use reflection to access the properties within your type:

class MyType
{
    public int prop1 { get; }
    public string prop2 { get; }
    public int[] prop3 { get; }
    public int prop4 { get; }
    public string prop5 { get; }
    public string prop6 { get; }

    public List<string> GetAllPropertyValues()
    {
        List<string> values = new List<string>();
        foreach (var pi in typeof(MyType).GetProperties())
        {
            values.Add(pi.GetValue(this, null).ToString());
        }

        return values;
    }
}

请注意，反射速度较慢，如果有更好的方法，则不应使用此功能.例如，当您知道只有6个属性时，只需逐一浏览它们即可.

Note that reflection is slow and you shouldn’t use this if there is a better way. For example when you know that there are only 6 properties, just go through them individually.
