C#基础-005字符介绍

namespace 字符
{
class Program
{
static void Main(string[] args)
{
char a = ‘时’;
char b = ‘建’;
Console.WriteLine((int)a + (int)b);//50416是字符’时’和’建’的Unicod之和
char c = ‘0’;
Console.WriteLine((int)c);//4是0的ASCII码值
Console.ReadKey();
//+=、-=、*=、/= 的使用
int num1 = 1;
num1 += 1;//num1 = num1 + 1;
Console.WriteLine(num1);//2
int num2 = 2;
num2 -= 1;//num2 = num2 - 1;
Console.WriteLine(num2);//1
int num3 = 3;
num3 = 5;//num3 = num3 5;
Console.WriteLine(num3);//15
int num4 = 6;
num4 /= 2;//num4 = num4 / 2;
Console.WriteLine(num4);//3
Console.ReadKey();
char shi = ‘时’;
Console.WriteLine((int)shi);//强制类型转换，26102
char jian = ‘建’;
Console.WriteLine(jian)//建
Console.WriteLine(” ” + shi + jian);//字符串在字符前和中间，运算结果是字符串
Console.WriteLine(shi + ” ” + jian);
Console.WriteLine(shi + jian + ” “);//字符串在字符后，运算结果也是字符串，但是前面的字符是按数字运算的，整体是字符串类型
Console.ReadKey();
}
}
}
//注：字符和数字是一一对应的，每一个字符都对应于一个阿拉伯数字
