DateTime.ToString() format question

[Jimmy [Used-Disks]]

It seems that I cannot not pass "h", "hh", "H", or "HH" (but nothing else)
to the ToString() method of a DateTime. It raises an excaption: "Input
string was not in a correct format."

So my question is: How can I convert the date time to a string, if I only
want the hours to show?

Thanks -

This is actually by design. For details read the Standard DateTime Format
Strings & Custom DateTime Format Strings.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpcondatetimeformatstrings.asp

A single character is interpreted as a Standard DataTime format, "H" & "h"
are not standard DateTime format strings. Hence those two cause exceptions.
A Custom DateTime format needs to be at least 2 characters.

Under VS.NET 2003 (.Net 1.1) "HH" & "hh" do not cause exceptions.

If you want just the hour, why not use the Hours property, then format that?

Dim d As DateTime
Dim s As String = d.Hour.ToString()

Of course you will get a 24 hour hour.

Hope this helps
Jay
