This is a culture problem

try to use ParseExact:

DateTime.ParseExact(Request.Params["dFrom"], "MM/dd/yyyy", CultureInfo.InvariantCulture)

Hope this helps.

I was having this same problem, it was working locally as dd-mm-yy but after publishing my site to the server I got error: "String was not recognized as a valid DateTime" so I changed it to mm-dd-yy and it worked on the server but then locally I was getting the error, I'm assuming because my asp.net host is in USA so the server date format is different from here in Australia. So to fix this annoying problem I simply changed the date setting in my control panel to mm-dd-yy and now no more DateTime errors :)

Supply to convert culture(IFormatProvider). http://msdn.microsoft.com/en-us/library/9xk1h71t.aspx

You might want to try using DateTime.Parse() instead of Convert.ToDateTime

DateTime dFrom = DateTime.Parse(Request.Params["dFrom"]);
DateTime dTo = DateTime.Parse(Request.Params["dTo"]);

ParseExact with the culture information is probably a better answer than this, see alexl's answer – lxalln Apr 15 '11 at 10:25

You could try DateTime.Parse(string) and see if it gets a better result, otherwise the GET-string should be in another format. Also the CurrentCulture could modify the output.
