C#遍历Dictionary方法



Dictionary<string, int> d = new Dictionary<string, int>();

foreach (KeyValuePair<string, int> pair in d)
{

Console.WriteLine("{0}, {1}",
pair.Key,
pair.Value);
}

Dictionary<string, int> list = new Dictionary<string, int>();
//C#3.0以上版本

foreach (var item in list)
{
Console.WriteLine(item.Key + item.Value);
}

//KeyValuePair<T,K>
foreach (KeyValuePair<string, int> kv in list)
{
Console.WriteLine(kv.Key + kv.Value);
}

//通过键的集合取

foreach (string key in list.Keys)
{
Console.WriteLine(key + list[key]);
}

//直接取值
foreach (int val in list.Values)
{
Console.WriteLine(val);
}

//非要采用for的方法也可
List<string> test = new List<string>(list.Keys);
for (int i = 0; i < list.Count; i++)
{
Console.WriteLine(test[i] + list[test[i]]);

}

IDictionary dictionary = new Hashtable();
foreach (DictionaryEntry entry in dictionary)
{
Object key = entry.Key;
Object val = entry.Value;
