C# 怎么提供像字典Dictionary那样的初始化方法

Question

new Dictionary<string, string>             {                 {"a","n" },                 {"b","n" },                 {"c","n" },                 {"d","n" },                 {"e","n" },                 {"f","n" },             };

Answer 1

public class TestA<Tkey,TValue> :IEnumerable<Tkey>
    {      
        public void Add(Tkey key,TValue value)
        {

        }        public IEnumerator<Tkey> GetEnumerator()
        {            throw new NotImplementedException();
        }

        IEnumerator IEnumerable.GetEnumerator()
        {            throw new NotImplementedException();
        }
    }

用ILSpy看下Dictionary就可以了。

Answer 2

这个初始化方式叫做属性构造器。
