Why can't I assign null to decimal with ternary operator?

Question

I can\'t understand why this won\'t work

decimal? compRetAmount = !string.IsNullOrEmpty(txtLineCompRetAmt.Text) 
    ? decimal.Parse(txtLineCompRetAmt.Text.R         


        

Answer 1

Try this:

decimal? compRetAmount = !string.IsNullOrEmpty(txtLineCompRetAmt.Text) ? 
                         decimal.Parse(txtLineCompRetAmt.Text.Replace(",", "")) : 
                         (decimal?) null;

The problem is that the compiler does not know what type nullhas. So you can just cast it to decimal?
