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
}
