Solving the 'Virtual method call in constructor' issue

Question

I am making a software in c#. I am using an abstract class, Instruction, that has these bits of code:

protected Instruction(InstructionSet instr         


        

Answer 1

You could pass in the real instruction into the base class constructor:

protected Instruction(..., Instruction realInstruction)
{
    //Some stuff

    if (DoesUseRealInstruction) {
        RealInstruction = realInstruction;
    }
}

public DerivedInstruction(...)
    : base(..., GetRealInstruction(...))
{
}

Or, if you really want to call a virtual function from your constructor (which I highly discorage you from) you could suppress the ReSharper warning:

// ReSharper disable DoNotCallOverridableMethodsInConstructor
    RealInstruction = GetRealInstruction(instructionSet, Argument);
// ReSharper restore DoNotCallOverridableMethodsInConstructor
