C＃反射获取字段或属性按名称

有没有办法提供一个名称，一个函数，然后返回这个名字的特定对象在任一领域或财产的价值？我试图解决它与空COALESCE运营商，但显然并不喜欢不同类型的（这也是有点怪我，因为空为空）。我可以分开它出来到是否为空，但必须有一个更好的方式来做到这一点。这里是我的功能，以及两行比较对象不进行编译，但我会离开他们在那里表现出什么，我试图做的。

Is there a way to supply a name to a function that then returns the value of either the field or property on a given object with that name? I tried to work around it with the null-coalesce operator, but apparently that doesn't like different types (which is also a bit weird to me because null is null). I could separate it it out into if nulls, but there has to be a better way to do this. Here is my function, and the two lines with Comparison objects don't compile, but I will leave them in there to show what I am trying to do.

private void SortByMemberName<T>(List<T> list, string memberName, bool ascending)
{
   Type type = typeof (T);
   MemberInfo info = type.GetField(memberName) ?? type.GetProperty(memberName);

   if (info == null)
   {
        throw new Exception("Member name supplied is neither a field nor property of type " + type.FullName);
   }

   Comparison<T> asc = (t1, t2) => ((IComparable) info.GetValue(t1)).CompareTo(info.GetValue(t2));
   Comparison<T> desc = (t1, t2) => ((IComparable) info.GetValue(t2)).CompareTo(info.GetValue(t1));

    list.Sort(ascending ? asc : desc);
}

我听说过一种叫做动态LINQ可以用来，但为了学习，我做我的方式。

I have heard of something called dynamic linq that could be used, but for the sake of learning, I am doing it my way.
