Solution 1

IndexOf is the only way to check without case sensitivity, but you could use Linq methods:

VB

Dim searchFor As String() = New String() {"lorum", "ipsum"}
Dim contains As Boolean = searchFor.Any(Function(s) data.IndexOf(s, StringComparison.OrdinalIgnoreCase) > 0)

You have a syntax error in your If statement:

Try:

VB.NET

If subject.IndexOf("lorem", 0, StringComparison.CurrentCultureIgnoreCase) > -1  OrElse subject.IndexOf("ipsum", 0, StringComparison.CurrentCultureIgnoreCase) > -1 Then
