C#中的map集合

C#中的Directory相当于Java中的Map集合

C# 中的map集合遍历取值方法如下：

 Dictionary map = new Dictionary();

 map.Add("1", "Chinese");
 map.Add("2", "Math");
 map.Add("3", "English");

 Console.WriteLine("Dictionary遍历方式：");
 Console.WriteLine("方法1：");
 foreach (var v in map )
 {
     Console.WriteLine("Key:" + v.Key + ";Value:" + v.Value);
 }

 Console.WriteLine("方法2：");
 foreach (KeyValuePair kvp in map )
 {
     Console.WriteLine("Key:" + kvp.Key + ";Value:" + kvp.Value);
 }

 Console.WriteLine("方法3：");
 foreach (string key in map.Keys)
 {
     Console.WriteLine("Key:" + key + ";Value:" + myDictionary[key]);
 }

 Console.WriteLine("方法4：");
 foreach (string value in map.Values)
 {
     Console.WriteLine("Value:"+value);
 }
