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

You can create a static method on derived class and put your logic there:

public enum InputType {
    Number = 1,
    String = 2,
    Date = 3
}

public class BaseClass {
    public BaseClass(InputType t) {
        // Logic
    }
}

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

    private static InputType GetInputType(Int32 parameter) {
        // Do something with parameter
        // and return an InputType

        return (InputType)Enum.Parse(typeof(InputType), parameter);
    }
}
