    一、实现效果

    1.1实现的功能

    ①添加信息到字典中;

    ②根据键获取值;

    ③根据值获取键;

    ④修改指定键的值;

    请问如何详细解释C概念?

    ⑤修改指定值为相同信息;

    ⑥根据键移除信息;

    ⑦根据值移除信息;

    1.2实现的功能效果图

    二、实现核心

    三、使用方法

    3.1引用命名空间

    using Utils;

    3.2使用示例

    using System; using System.Collections.Generic; using Utils; namespace Test_Dictionary { class Program { static void Main(string[] args) { Console.WriteLine("Hello World!"); //获取到字典信息 Dictionary<string, string> dic = GetDictionary(); Console.WriteLine($"1-开始获取到的字典的所有信息如下:"); ShowInfoOfDic(dic); //根据键获取到对应的值 string queryKey = "L1"; Console.WriteLine($"当前查询的键是:{queryKey}"); string tmpValue = DictionaryHelper.GetValueOfKey(dic,queryKey); Console.WriteLine($"2-获取到——键:L1对应的值是:{tmpValue}"); //根据值获取到对应的所有键 string queryValue = "23.4"; Console.WriteLine($"当前查询的值是:{queryValue}"); List<string> tmpKey = DictionaryHelper.GetKeyOfValue(dic, queryValue); ShowInfoOfList(tmpKey); //修改指定键的值 string needModifyKey = "L4"; string replaceValue1 = "66"; Console.WriteLine($"当前需要修改的键是:{needModifyKey}_替换为的值是:{replaceValue1}"); DictionaryHelper.ModifyInfoOfKey(dic, needModifyKey, replaceValue1); Console.WriteLine($"修改的键是:{needModifyKey}_替换为的值是:{replaceValue1}后所有内容如下:"); ShowInfoOfDic(dic); //修改指定值为相同信息 string needModifyValue = "23.6"; string replaceValue = "33.9"; Console.WriteLine($"当前需要修改的值是:{needModifyValue}_替换为的值是:{replaceValue}"); DictionaryHelper.ModifyInfoOfValue(dic,needModifyValue,replaceValue); Console.WriteLine($"修改的值是:{needModifyValue}_替换为的值是:{replaceValue}后所有内容如下:"); ShowInfoOfDic(dic); //根据键移除信息 string curRemoveKey = "L3"; Console.WriteLine($"当前移除的键是:{curRemoveKey}"); DictionaryHelper.RemoveInfoOfKey(dic,curRemoveKey); Console.WriteLine($"移除的键是:{curRemoveKey}后所有内容如下:"); ShowInfoOfDic(dic); //根据值移除信息 string curRemoveValue = "23.4"; Console.WriteLine($"当前移除的值是:{curRemoveValue}"); DictionaryHelper.RemoveInfoOfValue(dic, curRemoveValue); Console.WriteLine($"移除的值是:{curRemoveValue}后所有内容如下:"); ShowInfoOfDic(dic); Console.ReadLine(); } //获取一个字典 public static Dictionary<string, string> GetDictionary() { Dictionary<string, string> dic = new Dictionary<string, string>(); DictionaryHelper.AddInfoToDic(dic, "L1","23.4"); DictionaryHelper.AddInfoToDic(dic, "L2", "23.6"); DictionaryHelper.AddInfoToDic(dic, "L3", "23.8"); DictionaryHelper.AddInfoToDic(dic, "L4", "23.4"); DictionaryHelper.AddInfoToDic(dic, "L5", "23.6"); DictionaryHelper.AddInfoToDic(dic, "L6", "23.4"); return dic; } //显示字典中的所有信息 private static void ShowInfoOfDic(Dictionary<string,string> dic) { if (dic == null || dic.Count < 1) return; foreach (var item in dic) { Console.WriteLine($"键:{item.Key} 值:{item.Value}"); } Console.WriteLine($"--------------显示信息完成______当前字典:{dic.GetType().Name} 共有数据:{dic.Count} 条\r\n"); } //显示列表信息 private static void ShowInfoOfList(List<string> list) { if (list == null || list.Count < 1) return; foreach (var item in list) { Console.WriteLine($"对应内容:{item}"); } Console.WriteLine($"--------------显示信息完成______当前列表:{list.GetType().Name} 共有数据:{list.Count} 条\r\n"); } }//Class_end }
