Formatting

Dim sResult As String 
sResult = System.String.Format("{0:MM\/dd\/yyyy}", System.DateTime.Now())

Formatting Dates

Dim dtDateTime As System.DateTime 
dtDateTime As New System.DateTime(2002, 1, 6, 18, 30, 20) 

ToLongDateString

This format does not always display correctly and will depend on local settings.
It only displays the following format when the settings are US

System.DateTime dtDateTime; 
dtDateTime = new System.DateTime(2020,1,6,18,30,20); 
dtDateTime.ToLongDateString = "Sunday, January 06, 2020" 

When the settings are UK the format is as follows:

dtDateTime.ToLongDateString = "January 06, 2002" 

ToShortDateString

This format does not always display correctly and will depend on local settings.

dtDateTime.ToShortDateString = 01/06/2002

Dim sDateString As String 
sDateString = Now().ToString("dd mmm yy") 
sDateString = System.DateTime.ToString(Now())
