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..

UHD 4K vs DCI 4K 해상도 차이점 UHD 4K 및 DCI 4K는 디스플레이 및 영화 산업에서 사용되는 두 가지 해상도입니다. UHD 4K : 3840 x 2160 픽셀 DCI 4K : 4096 x 2160 픽셀 UHD(Ultra-High-Definition) 4K는 Full HD(1920 x 1080) 해상도의 4배인 3840 x 2160 픽셀의 해상도를 말합니다. 소비자용 4K TV 및 모니터에 사용되는 표준 해상도입니다. 반면 DCI(Digital Cinema Initiatives) 4K는 4096 x 2160 픽셀의 해상도를 말하며 UHD 4K보다 화면비가 약간 더 넓습니다. 이 해상도는 영화관의 디지털 영화 프로젝션에 사용되며 고급 전문 영화 제작 및 포스트 프로덕션의 표준입니다. 화질..
