Display numbers in C#

In C#, you can put a comma after every number in a string and convert an integer to a string with padding zeros using various methods. Here are some examples:

Putting a Comma After Every Number

int number = 123456789;
string formattedNumber = string.Format("{0:n0}", number);

In this example, the number variable contains an integer value. The string.Format method is called with the format string "{0:n0}" as the first argument, and the number variable as the second argument. The n0 format specifier specifies that a comma should be added after every three digits of the number. The resulting string is stored in the formattedNumber variable.

Converting int to String with Padding Zeros

int number = 123;
string paddedNumber = number.ToString("D5");

In this example, the number variable contains an integer value. The ToString method is called on the number variable with the format string "D5" as the argument. The D format specifier specifies that the number should be formatted with leading zeros to a minimum width of 5 digits. The resulting string is stored in the paddedNumber variable. Note that the number of zeros in the format string should be adjusted based on the desired minimum width of the resulting string.

C# display integer in console

int number = 42;
Console.WriteLine(number);

Formatting numbers in C#

int number = 1234567;
Console.WriteLine("{0:N}", number);  // Outputs: 1,234,567

C# display float with specific precision

float floatValue = 3.14159265359f;
Console.WriteLine("{0:F2}", floatValue);  // Outputs: 3.14

Displaying double values in C#

double doubleValue = 123.456789;
Console.WriteLine(doubleValue);

C# format currency string

decimal currencyValue = 12345.67m;
Console.WriteLine("{0:C}", currencyValue);  // Outputs: $12,345.67

C# convert number to string

int number = 42;
string numberString = number.ToString();

Displaying hexadecimal numbers in C#

int number = 255;
Console.WriteLine("{0:X}", number);  // Outputs: FF

C# scientific notation display

double scientificValue = 1.23e4;
Console.WriteLine("{0:E}", scientificValue);  // Outputs: 1.230000E+004

Formatting percentage values in C#

double percentageValue = 0.75;
Console.WriteLine("{0:P}", percentageValue);  // Outputs: 75.00%

C# display numbers with leading zeros

int number = 42;
Console.WriteLine("{0:D3}", number);  // Outputs: 042

Displaying negative numbers in parentheses in C#

int negativeNumber = -42;
Console.WriteLine("{0:(#)}", negativeNumber);  // Outputs: (42)

C# display numbers with trailing zeros

double number = 42.5000;
Console.WriteLine("{0:F2}", number);  // Outputs: 42.50

Displaying binary numbers in C#

int number = 42;
Console.WriteLine(Convert.ToString(number, 2));  // Outputs: 101010

Displaying roman numerals in C#

int number = 42;
string romanNumeral = ToRoman(number);
Console.WriteLine(romanNumeral);  // Outputs: XLII

// Function to convert integer to Roman numeral
static string ToRoman(int number)
{
    // Implementation logic to convert to Roman numeral
}
