上代码
#region 测试Dictionary<TKey,TValue>如何添加键重复的内容public class MyDictionaryComparer : IEqualityComparer<string>{public bool Equals(string x, string y){return x!=y;}public int GetHashCode(string obj){//throw new NotImplementedException();return obj.GetHashCode();}}public static void csDictionary(){Dictionary<string, string> dict = new Dictionary<string, string>(new MyDictionaryComparer());List<string> ts = new List<string>();// 输出内容到控制台Console.WriteLine("请输入第一个字符串:");while (true){string str = Console.ReadLine();if (string.IsNullOrEmpty(str)){continue;}ts.Add(str);var strarr = str.Split(',');dict.Add(strarr[0], strarr[1]);Console.WriteLine("Dictionary");foreach (var item in dict){Console.WriteLine("键:"+item.Key + ";值:" + item.Value);}Console.WriteLine("List");foreach (var item in ts){Console.WriteLine("值:" + item);}}}#endregion</pre>
效果图:
正常情况下向Dictionary添加相同的键会报错,但是实现IEqualityComparer<TKey>接口 以后就不会报错了;
