An expression of the form
x <<= y
is evaluated as
x = x << y
except that x is only evaluated once. The << operator shifts x
left by an amount specified by y
.
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 = 1000; a <<= 4; Console.WriteLine(a); } }
16000
