Modifying parameter values before sending to Base constructor

Question

The title may be a bit ambiguous, but I couldn\'t think of a better way to word this.

I realize that I can not call a derived constructor prior to calling a base con

Answer 1

You say

I realize that I can not call a derived constructor prior to calling a base constructor

But then you show this code

public DerivedClass(int i)
    : base(value)
{
    // Is it possible to set "value" here?
    // Logic
}

When that code block is entered you base class constructor has already run. You can however modify the value in an expression before passing it to the base constructor (with some obvious constraints). However, you will not have access to 'value' unless it is an input to the constructor.
