C # Learning Diary---Boolean type of data type

Boolean type of value type:

Boolean types are used to denote the two concepts of ' true ' and ' false ', although they may seem simple, but they are very widely used. We know that computers use binary to represent a variety of data, with only 0 or 1 inside it. The Boolean type represents a logical variable of only 2, True or False.

In this case, we contrast the C + +, the meaning of Boolean type C/C + +, which means "true" or "false" values, 0 means ' false ' other than 0 of the number means ' true ' this irregular expression is discarded in C #. True, False in C # cannot be substituted with other values, there is no conversion between an integer type and a Boolean type, which means that converting an integer type to a Boolean type is illegal.

BOOL X=1//Error

BOOL X=true or x = false//correct

Next, define a Boolean variable and output:

Using System;  Using System.Collections.Generic;  Using System.Linq;  Using System.Text;    Namespace Example  {      class program      {          static void Main (string[] args)          {              bool b=true;            Console.WriteLine (b);}}  

The result is:

     True
