How to Validate Date based on format “MM/dd/YYYY” in VB.NET

Here is the sample code snippet which I wrote to do date validation for a particular format and culture.

   1: Private Function validateDateFormat(ByVal strDate As String) As Boolean

   2:     Dim isValid As Boolean = True

   3:     Dim provider As CultureInfo = CultureInfo.GetCultureInfo("en-us")

   4:     Dim formats As String = "d" '"MM/dd/yyyy"

   5:     Dim dateValue As DateTime

   6:     Try

   7:         If DateTime.TryParseExact(strDate, formats, provider, DateTimeStyles.None, dateValue) Then

   8:             isValid = True

   9:         Else

  10:             isValid = False

  11:         End If

  12:     Catch ex As Exception

  13:  

  14:     End Try

  15:     Return isValid

  16: End Function

You can change the formats and CultureInfo to your own custom information. Here is my pervious blog which describes how formatting date time can be done using string object.
