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 perform multiplication.
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 *= 6; Console.WriteLine(a); } }
