- How to implement the single responsibility principle using C#?
- A class should have only one reason to change. Definition - In this case, responsibility is considered as a reason for change. This principle states that if we have two reasons for changing a class, we must split the functionality into two classes. Each class handles only one responsibility, and if we need to make a change in the future, we will make it in the class that handles it. When we need to make changes to a class that has more responsibilities, that change may affect other functionality related to other responsibilities of that class. Sample Code Before Single Responsibility Principle usingSystem;usingSystem.Net.Mail;namespaceSolidPrinciples.Single.Responsibility

- C# program to calculate total number of digits in a number
- Let's assume the number we have is 12. We declared and initialized a uint variable by assigning a decimal literal. uintval=12; The binary representation of 12 is −1100. The number of digits above is 4, so to find the total number of digits, use the Math.log() method −uintres=(uint)Math.Log(val,2.0)+1; Example You can try running the following code to calculate the total number of digits in a number.

- C# program to check if there are K consecutive 1's in a binary number
- To check if there are consecutive 1's in a binary number, you need to check 0 and 1. First, set a bool array for 0 and 1 i.e. false and true -bool[]myArr={false,true,false,false,false,true,true,true}; for 0, set the count to 0-if(myArr [i]==false) count=0; For 1, increment the count and set the result. The Max() method returns the larger of the two numbers -count++;res=Math.Max(res,count);Example The following is to check whether there are K consecutive 1's in a binary number

- Final local variables in C#
- To make a local variable final, use the read-only keyword in C# because it is not possible to implement the final keyword. The read-only keyword allows a variable to be assigned a value only once. Fields marked "read-only" can only be set once during object construction and cannot be changed. Let's look at an example. Below, we set the empCount field to be read-only and cannot be changed once assigned. Example classDepartment{ readonlyintempCount; Employee(intempCount){ &nb

- How to rotate an array k times using C#?
- Given an array and a number k, the problem states that we need to rotate the array k times. If the given number is 3, the array must be rotated 3 times. Create a function reverse that takes an array, a starting position, and an ending position as parameters. In the first step, the reverse method is called from 0 to the length of the array. In the second step, the reverse method is called from 0 to k-1. In the third step, the reverse method is called from k+1 to the array length. Example Demonstration usingSystem;namespaceConsoleApplication{ publicclassArrays{

- What is the usage of DelegatingHandler in Asp.Net webAPI C#?
- In a message handler, a series of message handlers are chained together. The first handler receives the HTTP request, does some processing, and then hands the request to the next handler. At some point, a response is created and returned to the chain. This pattern is called delegate handler. In addition to the built-in server-side message handlers, we can also create our own server-side HTTP message handlers. To create a custom server-side HTTP message handler in ASP.NET Web API, we use DelegatingHandler. We have to create a class derived from System.Net.Http.DelegatingHandler. The custom class should then
