在DateTime值中转换Cookie字符串

Question

I need convert one Cookie string value in DateTime value in c#.

The cookie is valid because if try this:

Response.Write(Request.Cookies["dt"].Value + "<br />");

In output I have:

08/07/2015

I can't convert this Cookie string on DateTime.

I have tried this method:

DateTime DataCookie;    
DataCookie = DateTime.ParseExact(Request.Cookies["dt"].Value, "yyyy-MM-dd", CultureInfo.InvariantCulture);

But I have thie error:

String was not recognized as a valid DateTime.

Wath's a wrong?

Answer 1

Clearly, your format and string doesn't exactly match.

From documentation ;

Converts the specified string representation of a date and time to its DateTime equivalent using the specified format and culture-specific format information. The format of the string representation must match the specified format exactly.

Use dd/MM/yyyy format instead.

DataCookie = DateTime.ParseExact(Request.Cookies["dt"].Value,
                                 "dd/MM/yyyy", 
                                 CultureInfo.InvariantCulture);
