您可能会使用字典，例如
Dictionary<string,object> properties;
我认为在大多数情况下，类似的事情都是这样完成的。
无论如何，使用set和get访问器创建“真实”属性不会获得任何好处，因为它将仅在运行时创建，并且您不会在代码中使用它。
这是一个示例，显示了可能的过滤和排序实现（无错误检查）：
using System;using System.Collections.Generic;using System.Linq;namespace ConsoleApplication1 { class ObjectWithProperties { Dictionary<string, object> properties = new Dictionary<string,object>(); public object this[string name] { get { if (properties.ContainsKey(name)){ return properties[name]; } return null; } set { properties[name] = value; } } } class Comparer<T> : IComparer<ObjectWithProperties> where T : IComparable { string m_attributeName; public Comparer(string attributeName){ m_attributeName = attributeName; } public int Compare(ObjectWithProperties x, ObjectWithProperties y) { return ((T)x[m_attributeName]).CompareTo((T)y[m_attributeName]); } } class Program { static void Main(string[] args) { // create some objects and fill a list var obj1 = new ObjectWithProperties(); obj1["test"] = 100; var obj2 = new ObjectWithProperties(); obj2["test"] = 200; var obj3 = new ObjectWithProperties(); obj3["test"] = 150; var objects = new List<ObjectWithProperties>(new ObjectWithProperties[]{ obj1, obj2, obj3 }); // filtering: Console.WriteLine("Filtering:"); var filtered = from obj in objects where (int)obj["test"] >= 150 select obj; foreach (var obj in filtered){ Console.WriteLine(obj["test"]); } // sorting: Console.WriteLine("Sorting:"); Comparer<int> c = new Comparer<int>("test"); objects.Sort(c); foreach (var obj in objects) { Console.WriteLine(obj["test"]); } } }}
