Java has CopyOnWriteArrayList, but C# does not have it. For that, the SynchronizedCollection Class in C#, should be preferred.The SyncronizedCollection has a thread-safe collection containing objects of a type. Here is the syntax.public class SynchronizedCollection : IList, ICollection, IEnumerable, IEnumerable, IList, ICollectionAbove, T is the type of object.The following are the properties of the SyncronizedCollection class in C# −Sr.No.Property Name & Description1CountCounts the number of elements in the thread-safe collection.2Item[Int32]Gets an element from the thread-safe collection with a specified index.3ItemsGets the list of elements contained in the thread-safe collection.4SyncRootGets the object used to synchronize access to the thread-safe collection.Read More
Use the CSS :only-child selector to style every element that is the only child of its parent.ExampleYou can try to run the following code to implement the :only-child selectorLive Demo p:only-child { background: orange; } Heading This is a paragraph. This is a paragraph. This is a paragraph. This is a paragraph. Output
The Logistic regression is a linear model used for binomial regression. It is used in medical science and to predict a customer’s tendency to purchase a product. It makes use of predictor variables for this purpose.Logistic Regression allows easier analysis of results in the form of odds ratios and statistical hypothesis testing.A generalized linear model has taken input for a non-linear link function. The linear model has the following form −z = c1x1 + c2x2 + … cnxn + i = ct x + iHere,c is the coefficient vector, i is the intercept value x is the observation vector
To create a Column store table, you need to enter “Column” keyword in Create table command.Create column Table Test_ColumnTB1 ( Cust_ID INTEGER, Cust_NAME VARCHAR(10), PRIMARY KEY (Cust_ID) );
To make code reusable in C#, use Interfaces. Interfaces define properties, methods, and events, which are the members of the interface. Interfaces contain only the declaration of the members. It is the responsibility of the deriving class to define the members. It often helps in providing a standard structure that the deriving classes would follow.For example, Shape Interface −public interface IShape { void display(); }Above we have declared an Interface Shape. You can notice that it begins with a capital “I”. It is a common convention that interfaces names begin with “I”.We have not added an access specifier above ... Read More
To format string literals in C#, use the String.Format method.In the following example, 0 is the index of the object whose string value gets inserted at that particular position −using System; namespace Demo { class Test { static void Main(string[] args) { decimal A = 15.2 m; string res = String.Format("Temperature = {0}°C.", A); Console.WriteLine(res); } } }In the following example, let us format string for double type.Example Live Demousing System; class Demo { public static void Main(String[] args) { ...

To format output in C#, let us see examples to format date and double type.Set formatted output for Double type.Example Live Demousing System; class Demo { public static void Main(String[] args) { Console.WriteLine("Three decimal places..."); Console.WriteLine(String.Format("{0:0.000}", 987.383)); Console.WriteLine(String.Format("{0:0.000}", 987.38)); Console.WriteLine(String.Format("{0:0.000}", 987.7899)); Console.WriteLine("Thousands Separator..."); Console.WriteLine(String.Format("{0:0, 0.0}", 54567.46)); Console.WriteLine(String.Format("{0:0, 0}", 54567.46)); } }OutputThree decimal places... 987.383 987.380 987.790 Thousands Separator... 54, 567.5 54, 567Set formatted output for DateTimeExample Live Demousing System; static class Demo { static void Main() ...

Declare a list.List < string > l = new List < string > ();Now, add elements to the list.// elements l.Add("Accessories"); l.Add("Footwear"); l.Add("Watches");Now convert it into a string.string str = string.Join(" ", l.ToArray());Let us see the final code to convert a list to string in C# −Exampleusing System; using System.Collections.Generic; class Demo { static void Main() { List < string > l = new List < string > (); // elements l.Add("Accessories"); l.Add("Footwear"); l.Add("Watches"); string str = string.Join(" ", l.ToArray()); Console.WriteLine(str); } }
To print duplicates from a list of integers, use the ContainsKey.Below, we have first set the integers.int[] arr = { 3, 6, 3, 8, 9, 2, 2 };Then Dictionary collection is used to get the count of duplicate integers.Let us see the code to get duplicate integers.Example Live Demousing System; using System.Collections.Generic; namespace Demo { public class Program { public static void Main(string[] args) { int[] arr = { 3, 6, ...
