Numeric formats C# with Example

// Integral types as hex 
string.Format("Hexadecimal: byte2: {0:x2}; byte4: {0:X4}; char: {1:x2}", 123, (int)'A'); 
// Integers with thousand separators 
string.Format("Integer, thousand sep.: {0:#,#}; fixed length: >{0,10:#,#}<", 1234567); 
// Integer with leading zeroes 
string.Format("Integer, leading zeroes: {0:00}; ", 1); 
// Decimals 
string.Format("Decimal, fixed precision: {0:0.000}; as percents: {0:0.00%}", 0.12); 
Output: 
Hexadecimal: byte2: 7b; byte4: 007B; char: 41 
Integer, thousand sep.: 1,234,567; fixed length: > 1,234,567< 
Integer, leading zeroes: 01; 
Decimal, fixed precision: 0.120; as percents: 12.00%
