c#遍历dictionary的几种方法
Dictionary<string, int> list = new Dictionary<string, int>();
list.Add("d", 1);
//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]]);
