如何使用 C# 只读属性？ 使用 get set 还是 lambda？

Question

namespace BrowserCompatabilityTests
{
    public static class Selectors
    {
        public static string activateDeviceButton = "#root > div > div > div > 
        div.row.activate--full-page > div:nth-child(2) > form > 
        div.form__actions.flex > button";
    }
}

I was asked to update this activateDevice field to a readonly getter property. Is there a C# convention to use {get,set} or lambda?

Answer 1

试试这个变体，它只设置一次属性值。

public static string activateDeviceButton { get; } = "#root > div > div > div > div.row.activate--full-page > div:nth-child(2) > form > div.form__actions.flex > button";

Answer 2

Look into getter and setter properties. Here is how it would potentially look:

public static string activateDeviceButton { get {return value;}}

Answer 3

You may declare ReadOnly properties either with a get (without set):

public string activateDeviceButton { get{ return someValue;} }

Or with a Lambda Expression:

   public string activateDeviceButton => someValue;
