What is Dictionaries in c#

A dictionary is a program data collection in C# programming. A system for keeping key-value pairs. A distinct key identifies each element in the C# dictionary data, and the matching program holds the value. When you need to rapidly check-up program values based on their keys, C# dictionaries come in handy.

In C#, dictionaries are implemented using the Dictionary<tkey, tvalue> class. Program keys are represented by the type tkey, and program values by the type tvalue. Program values may be of any kind, whereas keys must always be distinct inside the dictionary.

Programs written in C# that use dictionaries offer quick key lookup. When you look for a value in a dictionary using a key. In order to locate the appropriate value rapidly, the dictionary does a hash lookup. Because of this, dictionaries are a useful data structure for a variety of applications.

Using methods like Add, Remove, and trygetvalue, you may add, remove, and alter key-value pairs in a dictionary. Using foreach loops or LINQ queries, you may iterate through the keys and values in a dictionary as well.

Array in c#

An array in C# programming is a group of identically typed items that are kept in close range to one another in memory. A certain number of C# program objects can be stored in the array. And the C# array size cannot be modified during program execution. Which is supplied when the array is defined in the C# program.

The [] syntax in C# programming is used to build an array. Where the kinds of the array’s items are stated between brackets. Here is an illustration of how to make an array of integers.

Operator in c#

A program operator in the C# programming language is a symbol or keyword that executes a certain program operation on one or more operands. Which values or variables will be used in the C# program operation? C# programming gives a range of operators to the computer programmer. It may be utilized for a variety of program operations, including arithmetic, bitwise, logical, comparison, and others.

Here are a few illustrations of the most typical categories of operators used in C# programming.

Arithmetic operators: +, -, *, /, %

  • These operators are used in basic arithmetic operations. For example, for addition, subtraction, multiplication, division and modulus.

Comparison operators: ==, !=, <, >, <=, >=

  • These operators are used to compare two program values and return a Boolean result, which indicates whether the program variable comparison is true or false.

Logical operators: &&, ||, !

  • These operators are used to perform logical C# program operations such as AND, OR, and NOT.

Assignment operators: =, +=, -=, *=, /=, %=

  • These operators are used to assign a value to a C# variable or perform an arithmetic operation and assign the result to the variable.

Bitwise operators: &, |, ^, ~, <<, >>

  • These operators are used to perform bitwise operations on integer values. Like AND, OR, XOR, NOT, left shift and right shift, etc.
  • C# programming also provides you with many other operators. Such as the ternary operator?:, the null coalescing operator ??, and the conditional operator.

Operators are a fundamental part of C# programming, and are used extensively in expressions and statements to perform a variety of C# program operations.

C# with string

A string in C# is a collection of alphabetic letters. That denotes text or a string of words. Strings are one of the most extensively used data types in C#, and they are utilized for a broad variety of computer activities. Including handling data, presenting program results, and saving user input, among other things.

Here are a few C# examples of string use.

Declaring and initializing a string variable.

String teststring = “Welcome to mitacademys!”;

This code declares a string variable named teststring and initializes it with the value “Welcome to mitacademys!”.

C# switch statement

A switch statement in C# programming is a program control statement that enables you to run several programs blocks of code depending on the value of a variable or expression.

The fundamental syntax for a switch statement in C# programming is shown here.

Switch (expression)


    Case test1:

        // execute block of code statement when test is 1


    Case test2:

        // execute block of code statement when test is 2


    Case test3:

        // execute block of code statement when test is 3


    // you can add multiple switch case statement according to need


        // default statement only run while above all statements false



Typically, a variable or a program expression that evaluates to a program value may be used as the expression in a C# program switch statement and can be used to compare the value of each case. A colon and the block of code that will run if the expression equals the value follow each case. After the code for the matching case has been performed, the switch block is terminated using the break statement.

C# switch case statement in c#

In C# programming, the case statement and switch statement are frequently used to evaluate a program expression and run several program code blocks depending on the result of the expression.

An example of a switch statement with numerous case statements in a C# program is shown below.

Int c_value = 3;

Switch (c_value)


    Case 1:

        Console.writeline(“This is Python”);


    Case 2:

        Console.writeline(“This is Java”);


    Case 3:

        Console.writeline(“This is C# programming”);



        Console.writeline(“nothing else from above”);



In this illustration, the case block of code is executed after the switch statement has evaluated the value of the variable number. The program outputs “c_value is 3” because the value of c_value is 3, which causes the third case block to be run.

Any value that does not fit one of the case statements is handled by the default statement. In this illustration, the default block will be performed and the message “c_value is not 1, 2, or 3” will be produced if the number’s c_value is not one of the three.

To prevent the code from “falling” into the following case statement, each case statement must be followed by a break statement. If the break statement is absent. Thus, until a break statement or the end of a switch statement is reached, the program code will keep running.

In addition to supporting case statements, C#’s switch statement also executes default statements. The value of the expression being evaluated if none of the case statements match it. The default statement is therefore not required, although it is a good idea to add it to deal with unexpected or incorrect data.
