<<= Operator (C# Reference)

The left-shift assignment operator.

Remarks

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).

Example

class MainClass9
{
    static void Main()
    {
        int a = 1000;
        a <<= 4;
        Console.WriteLine(a);
    }
}
/*
Output:
16000
*/
