VB.NET Core Classes in a Nutshell

Name

OpCode

Synopsis

This structure describes a single MSIL instruction. It is used by the ILGenerator.Emit() method. Alternatively, use a field from the OpCodes class to supply a specific instruction without needing to create an OpCode object. Instructions are characterized by several pieces of information, represented as properties, such as OpCode, Operand, and flow control.

Public Structure OpCode

   Public ReadOnly Property Name As String  
   Public ReadOnly Property OpCodeType As OpCodeType  
   Public ReadOnly Property OperandType As OperandType  
   Public ReadOnly Property Size As Integer  
   Public ReadOnly Property StackBehaviourPop As StackBehaviour  
   Public ReadOnly Property StackBehaviourPush As StackBehaviour  
   Public ReadOnly Property Value As Short
