XmlDictionary and XmlDictionaryString classes to create WCF Message

It is common when you will create Message, you may use below classes

Let us investigate purpose of each class one by one.

XmlDictionary class allows us to create a private pair of Key and Value. This key-value pair can be used to represent

1. Element name
2. Attribute name
3. XML namespace declaration.

XmlDictionary class uses XmlDictionaryString class object to create key value pair. If you see below code, we are creating a XmlDictionary object and List of XmlDictionaryString.

dct is object of XmlDictionary and while adding string value in this it returns XmlDictionaryString object.

XmlDictionary dct = new XmlDictionary();
            List<XmlDictionaryString> lstData = new List<XmlDictionaryString>();
            lstData.Add(dct.Add("Bat"));
            lstData.Add(dct.Add("Ball"));
            lstData.Add(dct.Add("Wicket"));
            foreach (var r in lstData)
            {
                Console.WriteLine("Key  = {0}  and Value = {1}", r.Key, r.Value);
            }
            Console.ReadKey(true);

If you run above code you will get output as below,

We are simply adding returned XmlDictionaryString object to list of XmlDictionaryString.
