C# - Assignment Operators

Advertisements


There are following assignment operators supported by C#:

OperatorDescriptionExample
=Simple assignment operator, Assigns values from right side operands to left side operand C = A + B will assign value of A + B into C
+=Add AND assignment operator, It adds right operand to the left operand and assign the result to left operand C += A is equivalent to C = C + A
-=Subtract AND assignment operator, It subtracts right operand from the left operand and assign the result to left operand C -= A is equivalent to C = C - A
*=Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand C *= A is equivalent to C = C * A
/=Divide AND assignment operator, It divides left operand with the right operand and assign the result to left operand C /= A is equivalent to C = C / A
%=Modulus AND assignment operator, It takes modulus using two operands and assign the result to left operand C %= A is equivalent to C = C % A
<<=Left shift AND assignment operator C <<= 2 is same as C = C << 2
>>=Right shift AND assignment operator C >>= 2 is same as C = C >> 2
&=Bitwise AND assignment operator C &= 2 is same as C = C & 2
^=bitwise exclusive OR and assignment operator C ^= 2 is same as C = C ^ 2
|=bitwise inclusive OR and assignment operator C |= 2 is same as C = C | 2

Example

Try the following example to understand all the assignment operators available in C#:

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();
        }
    }
}

When the above code is compiled and executed, it produces the following result:

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
