C # convert data between binary, octal, decimal, and hexadecimal

Supplement: C # implements binary, octal, 10hexadecimal, and hexadecimal conversion freely.

In. NET FrameworkThe system. Convert class provides comprehensive conversion functions between various types and values. Two of these methods can be used to easily convert various hexadecimal values:

convert. toint32 (string value, int frombase) :

You can convert strings of different hexadecimal values to numbers. The frombase parameter is in the hexadecimal format and can only be 2, 8, 10, or 16:

For example, the result of convert. toint32 ("0010", 2) execution is 2;

Convert. tostring (INT value, int tobase ):

You can convert a number to a string format of different hexadecimal values. The tobase parameter can only be 2, 8, 10, or 16:

For example, the result of convert. tostring (0010) execution is"

 

/ decimal to binary

console. writeline (" binary representation of decimal 166:" + convert. tostring (166, 2);

/ decimal to octal conversion

console. writeline (" octal decimal 166:" + convert. tostring (166, 8);

/ convert decimal to hexadecimal

console. writeline (" hexadecimal representation of decimal 166:" + convert. tostring (166, 16);

/ binary to decimal

console. writeline (" decimal 111101:" + convert. toint32 ("111101", 2);

/ octal to decimal

console. writeline (" octal 44 in decimal format:" + convert. toint32 ("44", 8);

/ hexadecimal to decimal

Console. writeline (""+ Convert. toint32 (" cc ", 16 ));
