<<= 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
*/
