Firstly, let us create a dictionary −var d = new Dictionary(5);Now add the key and value −// add key and value d.Add("car", 25); d.Add("bus", 28); d.Add("motorbike", 17);Use orderby to order by values −var val = from ele in d orderby ele.Value ascending select ele;We have set ascending above to sort ...

The Array.SyncRoot property is used to get an object that can be used to synchronize access to the Array. The classes that have arrays can also use the SyncRoot property to implement their own synchronization.Enumerating through a collection is not a thread safe procedure.

The Array.IsSynchronized property in C gets a value indicating whether access to the Array is synchronized.The IsSynchronized property is implemented by Arrays because it is needed by the System.Collections.ICollection interface. Classes using arrays can also implement own synchronization using the SyncRoot property.The following is the syntax −public bool IsSynchronized { ... Read More

To determine if a string has unique characters or not, firstly check a word in the string with the next word −for (int j = i + 1; j < val.Length; j++) {    if (val[i] == val[j]) }If you find a match, that would mean the string do not ... Read More

Interning of string optimizes memory and performance.Through this, you can put strings in the runtime's shared string pool.Let us see an example −Example Live Demousing System; using System.Text; public class Demo {    public static void Main() {       string str1 = new StringBuilder().Append("Car is a ").Append("Vehicle").ToString();   ...
