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