运算符是指示编译器执行特定数学或逻辑操作的符号。
以下是 C# 中的赋值运算符。
| 运算符 | 描述 | 示例 |
|---|---|---|
| = | 简单赋值运算符，将右侧操作数的值赋给左侧操作数 | C = A + B 将 A + B 的值赋给 C |
| += | 加法与赋值运算符，将右侧操作数与左侧操作数相加，并将结果赋给左侧操作数 | C += A 等同于 C = C + A |
| -= | 减法与赋值运算符，它将左操作数减去右操作数，并将结果赋给左操作数 | C -= A 等同于 C = C - A |
| *= | 乘法与赋值运算符，它将右操作数与左操作数相乘，并将结果赋给左操作数 | C *= A 等同于 C = C * A |
| /= | 除法与赋值运算符，它将左操作数除以右操作数，并将结果赋给左操作数 | C /= A 等同于 C = C / A |
| %= | 模数与赋值运算符，使用两个操作数取模，并将结果赋给左操作数操作数 | C %= A 等同于 C = C % A |
| <<= | 左移与赋值运算符 | C <<= 2 与 C = C << 2 相同 |
| >>= | 右移与赋值运算符 | C >>= 2 与 C = C >> 2 相同 |
| &= | 按位与赋值运算符 | C &= 2 与 C = C & 相同2 |
| ^= | 按位异或和赋值运算符 | C ^= 2 与 C = C ^ 2 相同 |
| |= | 按位异或和赋值运算符 | C |= 2 与 C = C | 2 相同 |
示例
using System;
namespace Demo {
class Program {
static void Main(string[] args) {
int a = 21;
int c;
c = a;
Console.WriteLine("Value of c = {0}", c);
c += a;
Console.WriteLine("Value of c = {0}", c);
c -= a;
Console.WriteLine("Value of c = {0}", c);
c *= a;
Console.WriteLine("Value of c = {0}", c);
c /= a;
Console.WriteLine("Value of c = {0}", c);
c = 200;
c %= a;
Console.WriteLine("Value of c = {0}", c);
c <<= 2;
Console.WriteLine("Value of c = {0}", c);
c >>= 2;
Console.WriteLine("Value of c = {0}", c);
c &= 2;
Console.WriteLine("Value of c = {0}", c);
c ^= 2;
Console.WriteLine("Value of c = {0}", c);
c |= 2;
Console.WriteLine("Value of c = {0}", c);
Console.ReadLine();
}
}
}
输出
Value of c = 21 Value of c = 42 Value of c = 21 Value of c = 441 Value of c = 21 Value of c = 11 Value of c = 44 Value of c = 11 Value of c = 2 Value of c = 0 Value of c = 2
