如何獲取密鑰和值數組對象

Question

我想要得到數組對象鍵和值

Answer 1

你可以這樣做：

foreach(KeyValuePair<string, string> kv in st[u]) 
{ 
    string key = kv.Key; 
    string val = kv.Value; 
    //Business logic here 
} 

Answer 2

您可以用KeyValuePair嘗試獲得鍵和數組中的值。

foreach(KeyValuePair<string, string> kvp in m) 
{ 
Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value); 

} 

Answer 3

Hashtable hashtable = new Hashtable(); 
    hashtable[1] = "One"; 
    hashtable[2] = "Two"; 
    hashtable[13] = "Thirteen"; 

    foreach (DictionaryEntry entry in hashtable) 
    { 
     Console.WriteLine("{0}, {1}", entry.Key, entry.Value); 
    } 
You can use hashtable like this
