怎么把Dictionary<string,string >中的键和值输出来呀。

Dictionary<string,string > dic= new Dictionary<string, string>();
dic.Add("userName","jiou");
把userName和jiou输出来。

Answer 1

Dictionary<string, string> test = new Dictionary<string, string>();
test.Add("userName", "jiou");
test.Add("u2", "xx");

foreach (var dic in test)
{
Console.Write("key: {0}\nvalue: {1}\n", dic.Key, dic.Value);
}

Console.ReadKey();

Answer 2

foreach (string item in dic.Keys)
{
//键集合
}
foreach (string item in dic.Values)
{
//值集合
}

还有问题hi我~

Answer 3

Dictionary<string, string> dic = new Dictionary<string, string>();
dic.Add("userName", "jiou");
foreach (KeyValuePair<string, String> d in dic)
{
Console.WriteLine(d.Value);
}

Answer 4

//后续代码
System.Collections.IEnumerator iEnumerator = dic.Keys.GetEnumerator();
while (iEnumerator.MoveNext()) {
// 输出 iEnumerator.Current
// 输出 dic[iEnumerator.Current.ToString()]
}

Answer 5

Dictionary值能通过键去找值。
Dictionary.Keys;返回键的集合。
Dictionary.Values;返回值的集合。
