C＃支持以下赋值运算符 -
| 操作者 | 描述 | 例 |
|---|---|---|
| = | 简单赋值运算符，将右侧操作数的值分配给左侧操作数 | C = A + B将A + B的值分配给C |
| += | 添加AND赋值运算符，它将右操作数添加到左操作数并将结果赋给左操作数 | C + = A等于C = C + A. |
| -= | 减去AND赋值运算符，它从左操作数中减去右操作数，并将结果赋给左操作数 | C - = A相当于C = C - A. |
| *= | 乘以AND赋值运算符，它将右操作数与左操作数相乘，并将结果赋值给左操作数 | C * = A等于C = C * A. |
| /= | 除法AND赋值运算符，它将左操作数除以右操作数，并将结果赋值给左操作数 | C/= A相当于C = C/A. |
| %= | 模数AND赋值运算符，使用两个操作数获取模数，并将结果赋给左操作数 | C％= A等于C = C％A |
| <<= | 左移AND赋值运算符 | C << = 2与C = C << 2相同 |
| >>= | 右移AND赋值运算符 | C >> = 2与C = C >> 2相同 |
| &= | 按位AND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 |
| |= | 按位包含OR和赋值运算符 | C | = 2与C = C |相同 2 |
例子 (Example)
以下示例演示了C＃中可用的所有赋值运算符 -
using System;
namespace OperatorsAppl {
class Program {
static void Main(string[] args) {
int a = 21;
int c;
c = a;
Console.WriteLine("Line 1 - = Value of c = {0}", c);
c += a;
Console.WriteLine("Line 2 - += Value of c = {0}", c);
c -= a;
Console.WriteLine("Line 3 - -= Value of c = {0}", c);
c *= a;
Console.WriteLine("Line 4 - *= Value of c = {0}", c);
c /= a;
Console.WriteLine("Line 5 - /= Value of c = {0}", c);
c = 200;
c %= a;
Console.WriteLine("Line 6 - %= Value of c = {0}", c);
c <<= 2;
Console.WriteLine("Line 7 - <<= Value of c = {0}", c);
c >>= 2;
Console.WriteLine("Line 8 - >>= Value of c = {0}", c);
c &= 2;
Console.WriteLine("Line 9 - &= Value of c = {0}", c);
c ^= 2;
Console.WriteLine("Line 10 - ^= Value of c = {0}", c);
c |= 2;
Console.WriteLine("Line 11 - |= Value of c = {0}", c);
Console.ReadLine();
}
}
}
编译并执行上述代码时，会产生以下结果 -
Line 1 - = Value of c = 21
Line 2 - += Value of c = 42
Line 3 - -= Value of c = 21
Line 4 - *= Value of c = 441
Line 5 - /= Value of c = 21
Line 6 - %= Value of c = 11
Line 7 - <<= Value of c = 44
Line 8 - >>= Value of c = 11
Line 9 - &= Value of c = 2
Line 10 - ^= Value of c = 0
Line 11 - |= Value of c = 2
