Error in datetime variable

I want you to observe the below stuff very keenly:

Quote:

string carName = "";
DateTime dateFrom = "";

Whats special in the below code??? Why does it compile???

Quote:

string carName = "";
DateTime dateFrom = DateTime.Parse("");

What if i do?

Quote:

DateTime dateFrom = Convert.ToDateTime("");

Last question:

What if you ask me 50$ and i give you 50Rs what is the difference?


Thanks

Yes. Next!


Oh, you want more details? OK...
if you try to compile that, you will get an error:

Cannot implicitly convert type 'string' to 'System.DateTime'

Because you can't just assign a string to a DateTime any more than you can push a square peg in a round hole.
DateTime is not a string data type: it's a value which represents the number of milliseconds since and arbitrary point of time. Even if you wanted to assign a "blank" value to it, you can't, because just like integer it doesn't have a concept of "blank number" - it has a zero, just like integers do (DateTime.MinValue) but it doesn't have a "blank" value, so even if your tried the "proper" way to assign a string value to a DateTime by using DateTime.Parse or DateTime.ParseExact it would throw an exception if you tried to parse a blank string!

Think about what you are trying to achieve and there may be a better way to try and get there - but that isn't going to work!
