C# में Dictionary.ContainsValue () विधि का उपयोग यह जांचने के लिए किया जाता है कि Dictionary
सिंटैक्स
public bool ContainsValue (TValue val);
ऊपर, वैल खोजा जाने वाला मान है।
आइए अब Dictionary.ContainsValue () विधि को लागू करने के लिए एक उदाहरण देखें -
उदाहरण
using System; using System.Collections.Generic; public class Demo { public static void Main(){ Dictionary<string, string> dict = new Dictionary<string, string>(); dict.Add("One", "John"); dict.Add("Two", "Tom"); dict.Add("Three", "Jacob"); dict.Add("Four", "Kevin"); dict.Add("Five", "Nathan"); Console.WriteLine("Count of elements = "+dict.Count); Console.WriteLine("\nKey/value pairs..."); foreach(KeyValuePair<string, string> res in dict){ Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value); } if (dict.ContainsValue("Kevin")) Console.WriteLine("Value found!"); else Console.WriteLine("Value isn't in the dictionary!"); dict.Clear(); Console.WriteLine("Cleared Key/value pairs..."); foreach(KeyValuePair<string, string> res in dict){ Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value); } Console.WriteLine("Count of elements now = "+dict.Count); } }
आउटपुट
यह निम्नलिखित आउटपुट देगा -
Count of elements = 5 Key/value pairs... Key = One, Value = John Key = Two, Value = Tom Key = Three, Value = Jacob Key = Four, Value = Kevin Key = Five, Value = Nathan Value found! Cleared Key/value pairs... Count of elements now = 0
आइए अब Dictionary.ContainsValue () विधि को लागू करने के लिए एक और उदाहरण देखें -
उदाहरण
using System; using System.Collections.Generic; public class Demo { public static void Main(){ Dictionary<string, string> dict = new Dictionary<string, string>(); dict.Add("One", "Chris"); dict.Add("Two", "Steve"); dict.Add("Three", "Messi"); dict.Add("Four", "Ryan"); dict.Add("Five", "Nathan"); Console.WriteLine("Count of elements = "+dict.Count); Console.WriteLine("\nKey/value pairs..."); foreach(KeyValuePair<string, string> res in dict){ Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value); } if (dict.ContainsValue("Angelina")) Console.WriteLine("Value found!"); else Console.WriteLine("Value isn't in the dictionary!"); dict.Clear(); Console.WriteLine("Cleared Key/value pairs..."); foreach(KeyValuePair<string, string> res in dict){ Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value); } Console.WriteLine("Count of elements now = "+dict.Count); } }
आउटपुट
यह निम्नलिखित आउटपुट देगा -
Count of elements = 5 Key/value pairs... Key = One, Value = Chris Key = Two, Value = Steve Key = Three, Value = Messi Key = Four, Value = Ryan Key = Five, Value = Nathan Value isn't in the dictionary! Cleared Key/value pairs... Count of elements now = 0
