How to parse a date as iso in VB.NET

Question

I am trying to parse a date in vb.net as below.

Dim EndDate As Date = Date.Now.ToString("yyyy-MM-dd")
If Date.TryParseExact(txtEndDate.Text, "yyyy-MM-dd", CultureInfo.InvariantCulture, DateTimeStyles.None, EndDate) Then
  EndDate = txtEndDate.Text
Else
  txtEndDate.Text = EndDate
End If

I cannot understand why my code above outputs 00:00:00

DESIRED RESULT

If date input is not valid ISO date "yyyy-MM-dd" then

Set txtEndDate.Text and EndDate to date today as ** ISO .

---

EXAMPLE

if I pass in 2016-15-10

EndDate gets set to #10/15/2016 12:00:00 AM#

if I pass in asfd

EndDate gets set to #1/1/0001 12:00:00 AM#

Answer 1

Would you not just do this:

Dim EndDate As String = Date.Now.ToString("yyyy-M-d")
If Not Date.TryParseExact(txtEndDate.Text, "yyyy-M-d", CultureInfo.InvariantCulture, DateTimeStyles.None, EndDate) Then
  txtEndDate.Text = Date.Now.ToString("yyyy-M-d")
End If

If it is successful then EndDate will be returned as expected however if not then just set to today as you were above.
