%= Operator

The modulus assignment operator.

lhs %= expr

Where:

lhs
A storage location, property, or indexer.
expr
An expression.

Remarks

An expression using the %= assignment operator, such as

x %= y

is equivalent to

x = x % y

except that x is only evaluated once. The % operator is predefined for numeric types to compute the remainder after division.

The %= operator cannot be overloaded directly, but user-defined types can overload the % operator (see operator).

Example

// cs_operator_modulus_assignment.cs
using System;
class Test 
{
   public static void Main() 
   {
      int a = 5;
      a %= 3;
      Console.WriteLine(a);
   }
}

Output
