<<= Operator (C# Reference)

The left-shift assignment operator.

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 the number of bits specified by y.

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

// cs_operator_left_shift_assignment.cs
using System;
class MainClass
    static void Main() 
        int a = 1000;
        a <<= 4;
