Shifts an integer value to the left (in zeroes) by a specified number of bits, pushing the result onto the evaluation stack.

public static var Shl : OpCode;

Remarks

The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:

Format Assembly Format Description
62 shl Shifts an integer to the left (shifting in zeros).

The stack transitional behavior, in sequential order, is:

  1. A value is pushed onto the stack.
  2. The amount of bits to be shifted is pushed onto the stack.
  3. The number of bits to be shifted and the value are popped from the stack; the value is shifted left by the specified number of bits.
  4. The result is pushed onto the stack.

The shl instruction shifts the value (type int32, int64 or natural int) left by the specified number of bits. The number of bits is a value of type int32, int64 or natural int. The return value is unspecified if the number of bits to be shifted is greater than or equal to the width (in bits) of the supplied value.

Shl inserts a zero bit in the lowest position on each shift.

The following Emit constructor overload can use the shl opcode:

  • ILGenerator.Emit(OpCode)
