C# - StringDictionary - how to get keys and values using a single loop?

Question

I am using StringDictionary collection to collect Key Value Pairs.

E.g.:

StringDictionary KeyValue = new StringDictionary(); KeyValue.Add("A", "Load"); KeyValue.Add("C", "Save"); 

During retrieval i have to form two foreach to get keys and Values (i.e)

foreach(string key in KeyValue.Values) {    ... }  foreach(string key in KeyValue.Keys) {    ... } 

Is there any way to get the pair in single foreach ?

Answer 1

You can do a foreach loop on the dictionary, which will give you a DictionaryEntry in each iteration. You can access the Key and Value properties from that object.

foreach (DictionaryEntry value in KeyValue) {     // use value.Key and value.Value } 

Answer 2

The StringDictionary can be iterated as DictionaryEntry items:

foreach (DictionaryEntry item in KeyValue) {    Console.WriteLine("{0} = {1}", item.Key, item.Value); } 

I would suggest that you use the more recent Dictionary<string,string> class instead:

Dictionary<string, string> KeyValue = new Dictionary<string, string>(); KeyValue.Add("A", "Load"); KeyValue.Add("C", "Save");  foreach (KeyValuePair<string, string> item in KeyValue) {    Console.WriteLine("{0} = {1}", item.Key, item.Value); }
