How to use an assignment operator in C#?
Assign value to a variable using the assignment operator in C# −
The following are the assignment operators in C# −
| Operator | Description | Example |
|---|---|---|
| = | Simple assignment operator, Assigns values from right side operands to left side operand | C = A + B assigns 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 |
The following is an example −
Example
using System;
namespace OperatorsAppl {
class Program {
static void Main(string[] args) {
int a = 21;
int c;
c = a;
Console.WriteLine("Assignment Operator: {0}", c);
c += a;
Console.WriteLine("+= Value: {0}", c);
c -= a;
Console.WriteLine("+= Value: {0}", c);
c *= a;
Console.WriteLine("*= Value: {0}", c);
c /= a;
Console.WriteLine("/= Value: {0}", c);
c = 200;
c %= a;
Console.WriteLine("%= Value: {0}", c);
c <<= 2;
Console.WriteLine("<<= Value: {0}", c);
Console.ReadLine();
}
}
}Output
Assignment Operator: 21 += Value: 42 += Value: 21 *= Value: 441 /= Value: 21 %= Value: 11 <<= Value: 44
