C#对Dictionary内容的通用操作是什么(dictionary,开发技术)

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；

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；

三、使用方法

3.1引用命名空间

usingUtils;

3.2使用示例

usingSystem;usingSystem.Collections.Generic;usingUtils;namespaceTest_Dictionary{classProgram{staticvoidMain(string[]args){Console.WriteLine("HelloWorld!");//获取到字典信息Dictionary<string,string>dic=GetDictionary();Console.WriteLine($"1-开始获取到的字典的所有信息如下：");ShowInfoOfDic(dic);//根据键获取到对应的值stringqueryKey="L1";Console.WriteLine($"当前查询的键是：{queryKey}");stringtmpValue=DictionaryHelper.GetValueOfKey(dic,queryKey);Console.WriteLine($"2-获取到——键：L1对应的值是：{tmpValue}");//根据值获取到对应的所有键stringqueryValue="23.4";Console.WriteLine($"当前查询的值是：{queryValue}");List<string>tmpKey=DictionaryHelper.GetKeyOfValue(dic,queryValue);ShowInfoOfList(tmpKey);//修改指定键的值stringneedModifyKey="L4";stringreplaceValue1="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stringneedModifyValue="23.6";stringreplaceValue="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stringcurRemoveKey="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stringcurRemoveValue="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publicstaticDictionary<string,string>GetDictionary(){Dictionary<string,string>dic=newDictionary<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");returndic;}//显示字典中的所有信息privatestaticvoidShowInfoOfDic(Dictionary<string,string>dic){if(dic==null||dic.Count<1)return;foreach(varitemindic){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privatestaticvoidShowInfoOfList(List<string>list){if(list==null||list.Count<1)return;foreach(variteminlist){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}
