Decimal constants in C#
The decimal type in C# provides built-in constants to retrieve the minimum and maximum possible values for decimal numbers. These constants are useful for validation, range checking, and initialization purposes. Syntax Following is the syntax for declaring a decimal constant − decimal variableName = value M; Following is the syntax for accessing decimal constants − decimal.MaxValue // Maximum possible decimal value decimal.MinValue // Minimum possible decimal value Decimal Constants The decimal type provides two important constants − decimal.MaxValue − Returns the largest possible decimal ...
Read MoreC# OverflowException
The OverflowException in C# is thrown when an arithmetic operation results in a value that exceeds the range of the target data type. This commonly occurs during type conversions, arithmetic operations, or when parsing strings that contain values outside the acceptable range. Common Scenarios OverflowException is typically thrown in the following situations − Converting a string to an integer when the value exceeds int.MaxValue or int.MinValue Arithmetic operations that result in overflow (in checked context) Casting between numeric types where the source value is too large for the target type ...
Read MoreC# Program to check if a number is Positive, Negative, Odd, Even, Zero
In C#, you can determine if a number is positive, negative, odd, even, or zero using simple conditional statements and arithmetic operations. This involves checking the sign of the number and using the modulus operator to determine if a number is divisible by 2. Logic for Number Classification To classify a number, we use the following approaches − Positive/Negative/Zero: Compare the number with zero using relational operators. Odd/Even: Use the modulus operator (%) to check if the remainder when divided by 2 is zero. Number Classification Logic ...
Read MoreC# program to display factors of entered number
A factor of a number is any integer that divides the number evenly without leaving a remainder. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12 because each of these numbers divides 12 exactly. To find factors of a number in C#, we use the modulus operator (%) to check if the remainder is zero when dividing the number by potential factors. Algorithm The algorithm to find factors involves the following steps − Start with 1 and iterate through all numbers up to the given number For each number, check ...
Read MoreC# Program to display temporary file names
The Path.GetTempPath() method in C# retrieves the path of the system's temporary folder where temporary files are stored. This method is useful when your application needs to create temporary files or work with the system's designated temporary directory. Syntax Following is the syntax for using Path.GetTempPath() method − string tempPath = Path.GetTempPath(); Return Value The method returns a string representing the path to the system's temporary directory. On Windows, this is typically the path specified by the TEMP or TMP environment variables. On Unix-like systems, it's usually /tmp/. Using GetTempPath() to Display ...
Read MoreThe "0" custom format specifier in C#
The "0" custom format specifier in C# is a zero placeholder that ensures a digit appears in each specified position. If the value being formatted has a digit in that position, it displays the digit; otherwise, it displays a zero. This format specifier is particularly useful for creating fixed-width numeric displays, padding numbers with leading zeros, or ensuring decimal places are always shown. Syntax Following is the syntax for using the "0" custom format specifier − number.ToString("000") // For integers with leading zeros number.ToString("0.00") // For decimals with ...
Read MoreC# program to count upper and lower case characters in a given string
To count uppercase and lowercase characters in a string, we can iterate through each character and check if it falls within specific ASCII ranges. For uppercase letters, we check if the character is between 'A' and 'Z', while for lowercase letters, we check if it's between 'a' and 'z'. Syntax Following is the syntax for checking uppercase characters − if (myStr[i] >= 'A' && myStr[i] = 'a' && myStr[i] = 'a' && myStr[i] = 'A' && myStr[i]
Read MoreC# program to Display Hostname and IP address
To find the hostname of the current machine, use the Dns.GetHostName() method in C#. This method returns the host name of the local computer as a string. To get the IP addresses, use the IPHostEntry.AddressList property which provides an array of all IP addresses associated with the hostname. Syntax Following is the syntax for getting the hostname − string hostName = Dns.GetHostName(); Following is the syntax for getting IP addresses − IPHostEntry hostEntry = Dns.GetHostEntry(hostName); IPAddress[] addresses = hostEntry.AddressList; Example The following code demonstrates how to display hostname and ...
Read MoreC# program to replace all spaces in a string with '%20'
When working with strings in C#, you may need to replace spaces with '%20' for URL encoding or other formatting purposes. The Replace() method provides a simple way to substitute all occurrences of a character or substring with another value. Syntax Following is the syntax for using the Replace() method − string newString = originalString.Replace(oldValue, newValue); Parameters oldValue − The string or character to be replaced newValue − The string or character to replace with Return Value The method returns a new string with all occurrences of the specified ...
Read MoreWhat is the difference between a class and an object in C#?
When you define a class, you define a blueprint or template for a data type. The object is an instance of that class − a concrete implementation created from the blueprint. A class defines the structure and behavior, while objects are the actual entities that hold data and perform actions. The methods and variables that constitute a class are called members of the class. To access class members, you use the dot (.) operator after the object name. The dot operator links the name of an object with the name of a member. Class vs Object ...
