c# 赋值运算符

Assignment operators (Assignment (=) and compound assignments (+=, -+, *=, /=, %=)) are used to assign the value or an expression's result to the left side variable, following are the set of assignment operators,

赋值运算符(Assignment( = )和复合赋值( + = ， -+ ， * = ， / = ， ％= ))用于将值或表达式的结果赋给左侧变量，以下是赋​​值运算符集，

1. "=" – it is used to assign value or an expression's result to the left side variable

   “ =” –用于将值或表达式的结果分配给左侧变量

2. "+=" – it is used to add second operand to the existing operand's value and assigns it back (a+=b is equal to a=a+b)

   “ + =” –用于将第二个操作数添加到现有操作数的值并将其赋值回去(a + = b等于a = a + b)

3. "-=" – it is used to subtract second operand from the existing operand's value and assigns it back (a-=b is equal to a=a-b)

   “-=” –用于从现有操作数的值中减去第二个操作数并将其赋值回去(a- = b等于a = ab)

4. "/=" – it is used to divide second operand from the existing operand's value and assigns it back (a/=b is equal to a=a+b)

   “ / =” –用于将第二个操作数与现有操作数的值相除并将其赋值回去(a / = b等于a = a + b)

5. "*=" – it is used to multiply second operand with the existing operand's value and assigns it back (a*=b is equal to a=a*b)

   “ * =” –用于将第二个操作数与现有操作数的值相乘并赋值回去(a * = b等于a = a * b)

6. "%=" – it is used to get the remainder by dividing second operand with the existing operand's value and assigns it back (a%=b is equal to a=a%b)

   “％=” –用于通过将第二个操作数除以现有操作数的值来获得余数，并将其赋值回去(a％= b等于a = a％b)

Example:

例：

    Input:
int a = 10;
int b = 3;
//operations & outputs
a = 100;    //value of a will be 100
a += b;     //value of a will be 103
a -= b;     //value of a will be 100
a *= b;     //value of a will be 300
a /= b;     //value of a will be 100
a %= b;     //value of a will be 1

C# code to demonstrate example of assignment operators

C＃代码演示赋值运算符的示例

// C# program to demonstrate example of
// assignment operators
using System;
using System.IO;
using System.Text;
namespace IncludeHelp
{class Test
{// Main Method
static void Main(string[] args)
{int a = 10;
int b = 3;
Console.WriteLine("a: {0}", a);
a = 100; //assigment
Console.WriteLine("a: {0}", a);
a += b;
Console.WriteLine("a: {0}", a);
a -= b;
Console.WriteLine("a: {0}", a);
a *= b;
Console.WriteLine("a: {0}", a);
a /= b;
Console.WriteLine("a: {0}", a);
a %= b;
Console.WriteLine("a: {0}", a);
//hit ENTER to exit the program
Console.ReadLine();
}
}
}

Output

输出量

a: 10
a: 100
a: 103
a: 100
a: 300
a: 100
a: 1
