（HashTable）根据哈希表中的键获取值 [英] (HashTable)get value according to his key in hashtable

问题描述

我制作哈希表或添加一些键和值

就像那样

Hashtable Htbl = new Hashtable（）;

Htbl。添加（C100，思域）;

Htbl.Add（C200，Carolla）;

Htbl.Add（C300，BMW ）;

Htbl.Add（C400，Aulto）;



现在我想根据用户给出的价值它的关键是通过console.readline（）



简称（根据哈希表中的键获取值）



plz帮我

i make a hashtable or add some key and value
just like that
Hashtable Htbl = new Hashtable();
Htbl.Add("C100", "Civic");
Htbl.Add("C200", "Carolla");
Htbl.Add("C300", "BMW");
Htbl.Add("C400", "Aulto");

now i want to get value according to user give its key through console.readline()

in short(get value according to his key in hashtable)

plz help me

推荐答案

string _keyByUser =C100; //或者让用户输入密钥

string _valueStoredInHashTable = Htbl [ _keyByUser] .ToString（）;

string _keyByUser = "C100";//alternatively make user enter the key
string _valueStoredInHashTable = Htbl[_keyByUser].ToString();

看看这里它说明课程相当不错

Have a look here it explains the class pretty good

YOur probably looking for:

Console.WriteLine("For key = \"rtf\", value = {0}.", openWith["rtf"]);

Hashtable Htbl = new Hashtable();
Htbl.Add("C100", "Civic");
Htbl.Add("C200", "Carolla");
Htbl.Add("C300", "BMW");
Htbl.Add("C400", "Aulto");

int n = 1;
string test = Htbl [n].ToString();
Console.Writeline(test);

现在迭代循环以获取所有值...
