Question

My objects often has nullable types properties that used as SQL commands parameters.

I initialize them next way:

public int? Amount
{
    get
    {
        int i;
        int? amount = null;
        if (Int32.TryParse(Request["amount"], out i))
        {
            amount = i;
        }
        return amount;
    }
}

command.Parameters.Add("@amount").Value = (object)this.Amount ?? DbNull.Value;

How can I rewrite such initialization code to make it shorter or faster?

I like little bit rewrite of Randolpho’s and Marc’s code:

return Int32.TryParse(Request["amount"], out i)) ? (int?)i : (int?)null;
