Numerical hexadecimal conversion C #

 

In daily applications, commonly used numeric hexadecimalDecimal, octal, hexadecimal, and binary.

In. net, it is very simple and convenient to implement digital conversion. There are two general implementation methods:

• More common methods

System. Convert. toint ?? (?, Int frombase) // frombase indicates the base number, which can be 2, 8, 16 system. Convert. tostring (?, Int tobase) // tobase is the hexadecimal format to be converted. It can be 2, 8, or 16.

• It is applicable to interchange between 10-and 16-digit systems.

Int. parse (string S, system. Globalization. numberstyles. hexnumber) // and Int. tostring ("X ") //

Example of the first method:

string hexNumber = "0F";int digitNumber = System.Convert.ToInt32 ( hexNumber, 16 );hexNumber = System.Convert.ToString ( digitNumber, 16 );

Example of the second method:

int digitNumber = 100;string hexNumber = digitNumber.ToString ( "X" );digitNumber = int.Parse ( hexNumber, System.Globalization.NumberStyles.HexNumber );

Tostring ("? ") Common formatting methods:

Symbol	Description	Example	Output result	Remarks
C	Currency	(3.8). tostring ("C ")	￥3.80	Display Method of currency result, and System. Globalization. cultureinfo. currentculture Settings
D	Decimal digital	(38). tostring ("D6 ")	000038	"In" D6"6"Indicates the length of the returned string.
E	Scientific type	(3800). tostring ("e ")	3.800000e + 004
F	Float	(38). tostring ("F3 ")	38.000	"In" F3"3"Is the number of decimal places
G	General	(38). tostring ("G ")	38
N		(12345). tostring ("N ")	12,345.00
X	Hexadecimal	(38). tostring ("X ")	26
