C# Boolean In C#, a boolean is a data type that can have one of two values: true or false. Boolean values are typically used to represent the result of a comparison or a logical operation. You can declare a boolean variable like this: bool b = true; You can also use boolean operators to perform logical operations on boolean values. The most common boolean operators are: && (logical and): returns..

C# Strings In C#, a string is a sequence of characters that represent text. Strings are reference types and are implemented as instances of the System.String class. Here are some basic operations you can perform with strings in C#: Creating a string: string s1 = "hello"; string s2 = "world"; string s3 = s1 + " " + s2; // s3 is "hello world" Getting the length of a string: string s = "hello"; int..

C# Nullables C# nullable types were introduced to allow variables to have a value or a null reference. In C#, by default, value types (such as int, double, and bool) cannot be assigned a null value. Nullable types allow you to assign a null value to a value type by wrapping the value type in a Nullable structure. To declare a nullable type, you can use the ? modifier after the value type. For ex..

C# Operators C# provides a variety of operators that you can use to perform operations on variables and values. These operators include: Arithmetic operators: + (addition) - (subtraction) * (multiplication) / (division) % (modulus) ++ (increment) -- (decrement) Assignment operators: = (simple assignment) += (addition assignment) -= (subtraction assignment) *= (multiplication assignment) /= (divi..

C# Type Casting C# type casting is the process of converting a value of one data type to another data type. There are two types of type casting in C#: implicit casting and explicit casting. Implicit casting, also known as widening conversion, is the automatic conversion of a value of a smaller data type to a larger data type. For example, converting an int to a long. Implicit casting does not re..

C# Constants Constants are variables whose values cannot be changed once they are assigned. They are declared using the "const" keyword and can only be assigned a value at the time of declaration. Constants are typically used to define values that will remain fixed throughout the execution of a program, such as mathematical constants or values that are used frequently throughout the code. Here's..

C# Variables In C#, a variable is a named storage location that holds a value. Before you can use a variable in C#, you need to declare it with a data type. To declare a variable, you use the following syntax: data_type variable_name; Here's an example of declaring a variable: 1 2 int age; cs In this example, we're declaring a variable called age of type int. To assign a value to a variable, you..

C# Data Types In C#, there are two main categories of data types: value types and reference types. Value types are simple data types that store their value directly on the stack. They include: Numeric types: int, float, double, decimal, short, long, byte, sbyte, ushort, uint, and ulong. Boolean type: bool. Character type: char. Enumerations: enum. Reference types are more complex data types that..

C# Overview C# (pronounced "C sharp") is a modern, object-oriented programming language that was developed by Microsoft. It was first introduced in 2000 as part of Microsoft's .NET Framework, and since then it has become a popular choice for developing a wide variety of applications, including desktop software, web applications, and mobile apps. C# is designed to be simple, efficient, and type-s..

ArgumentException: Partial byte sequence encountered in the input. The error message "Partial byte sequence encountered in the input" is commonly encountered in .NET applications when working with encoded text, particularly when decoding UTF-8 encoded text into a string or char type. This error occurs when the input data is not a valid encoded sequence of characters, or when a partial encoded se..
