Can Contains Property Have many items(VB2008)

Salam

I have this code
if itm.Contains(".jpg") Or itm.Contains(".png") Or itm.Contains(".bmp") Or itm.Contains(".mpg") Or itm.Contains(".wmv")
' some code here
End If

Can contains be multible instead of using Or.

Hi Ahmad Al-najjr;

The parameter of the Contains is a simple string of one search criteria and not multiple.

You can have code as shown in the code snippet below.

Fernando
Imports System.Text.RegularExpressions
 
' Data source
Dim itm As New List(Of String)()
itm.AddRange(New String() {"File1.jpg", "File1.png", "File1.bmp", "File1.mpg", "File1.wmv", "File1.txt"})
 
' Find out if any of the strings in itm have the values jpg|png|bmp|mpg|wmv
' If any do assign those string to the list itmFound
Dim itmFound As List(Of String) = itm.FindAll(Function(f) Regex.IsMatch(f, "(jpg|png|bmp|mpg|wmv)"))
 
If itmFound.Count > 0 Then
    'some code here 
End If

To add the other file types change this line of code:
 
Dim itmFound As List(Of String) = itm.FindAll(Function(f) Regex.IsMatch(f, "(jpg|png|bmp|mpg|wmv)"))
 
To this:
 
Dim itmFound As List(Of String) = itm.FindAll(Function(f) Regex.IsMatch(f, "\.(jpg|png|bmp|mpg|wmv|mp4|avi|mp3)"))
