यह जाँचने के लिए कि सॉर्टेडलिस्ट ऑब्जेक्ट में C# में एक विशिष्ट कुंजी है या नहीं, कोड इस प्रकार है -
उदाहरण
using System; using System.Collections; public class Demo { public static void Main() { SortedList list = new SortedList (); list.Add("A", "Books"); list.Add("B", "Electronics"); list.Add("C", "Appliances"); list.Add("D", "Pet Supplies"); list.Add("E", "Clothing"); list.Add("F", "Footwear"); Console.WriteLine("Value associated with key E = "+list["E"]); list["E"] = "HDD"; Console.WriteLine("Value associated with key E [Updated] = "+list["E"]); Console.Write("Does the list has key C? = "+list.Contains("C")); } }
आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा -
Value associated with key E = Clothing Value associated with key E [Updated] = HDD Does the list has key C? = True
उदाहरण
आइए अब एक और उदाहरण देखें -
using System; using System.Collections; public class Demo { public static void Main(String[] args) { SortedList sortedList = new SortedList(); sortedList.Add("A", "1"); sortedList.Add("B", "2"); sortedList.Add("C", "3"); sortedList.Add("D", "4"); sortedList.Add("E", "5"); sortedList.Add("F", "6"); sortedList.Add("G", "7"); sortedList.Add("H", "8"); sortedList.Add("I", "9"); sortedList.Add("J", "10"); Console.WriteLine("SortedList elements..."); foreach(DictionaryEntry d in sortedList) { Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value); } Console.WriteLine("Count of SortedList key-value pairs = "+sortedList.Count); sortedList.RemoveAt(3); Console.WriteLine("\nEnumerator to iterate through the SortedList..."); IDictionaryEnumerator demoEnum = sortedList.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = "+ demoEnum.Value); Console.WriteLine("Count of SortedList key-value pairs (Updated) = "+sortedList.Count); Console.WriteLine("\nDoes the list has key C? = "+sortedList.Contains("C")); Console.WriteLine("Does the list has key M? = "+sortedList.Contains("M")); } }
आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा -
SortedList elements... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = D, Value = 4 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Count of SortedList key-value pairs = 10 Enumerator to iterate through the SortedList... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Count of SortedList key-value pairs (Updated) = 9 Does the list has key C? = True Does the list has key M? = False
