问正则表达式替换-有没有更好的方法来切换声明和赋值

EN

using System;

class Settings {
    public int ValueA { get; set; }
    public string ValueB { get; set; }
    public void CopySettings(Settings other) {
        ValueA = other.ValueA;
        ValueB = other.ValueB;
    }
}

class Program {
    static void Main(string[] args) {
        Settings a = new Settings() { ValueA = 3, ValueB = "something" };
        Settings b = new Settings();
        // and then you can do one the following, which will copy all settings
        // in both cases...
        b.CopySettings(a);
        a.CopySettings(b);
    }
}
