Tom,
As Shiva suggests, you can use String.IndexOfAny, something like: If strTest.IndexOfAny("ABC".ToCharArray) <> -1 Then
Debug.WriteLine("Found characters")
Else
Debug.WriteLine("Did NOT find characters!")
End If
Or
If strTest.IndexOfAny(New Char() {"A"c, "B"c, "C"c}) <> -1 Then
NOTE: "A"c is a char literal, while "A" is a string literal.
Depending on how often I was using the above, I would consider making the
char array Static to the routine.
Static anyOf() As Char = New Char() {"A"c, "B"c, "C"c}
If strTest.IndexOfAny(anyOf) <> -1 Then
Hope this helps

Tom,
You cannot, you should or use a Regex or use a loop with the normal indexof
Where the performance decission when to use the regex is in my opinion about
20 words to search for.

Tom,
I think you are going to have to create your own routine...
I would consider using a RegEx in that routine.
Const pattern As String = "cat|dog|sleep"
Static theRegEx As New System.Text.RegularExpressions.Regex(pattern,
Text.RegularExpressions.RegexOptions.Compiled)
If theRegEx.IsMatch(strTest) Then
Debug.WriteLine("Found strings")
Else
Debug.WriteLine("Did NOT find strings!")
End If
Of course if "cat","dog", "sleep" are dynamic, you could build the pattern
with String.Join:
Dim pattern As String = String.Join("|", New String() {"cat", "dog",
"sleep"})
If System.Text.RegularExpressions.Regex.IsMatch(patte rn, strTest)
Then
Which I used would depending on the whether or not the strings I was looking
for were static or dynamic & how often the routine was being called...
Hope this helps

First I tested if 'String' contains a 'Contains' method, but it doesn't
contain such a method.
BTW: My solution can be simply adapted by replacing 'AndAlso' with 'OrElse'
in order to check for the occurance of one (or more) of the substrings in
the string.
Its harder with RegEx to check to see if it contains all

Especially for longer strings, the way I propagate may be inefficient, but I

Longer input or longer list of words?
RegEx has no syntax that states "this & that" per se (you would need to
create a convoluted pattern), it only has "this or that" (via "this|that")
so checking for one of significant number of words with a regex is
relatively easy (see my other post). Checking for all of a list of words
with RegEx would be significantly hard!
As I've stated before, I would not worry about performance until the routine
was proven to be a performance problem. I would go with one of the two RegEx
I gave earlier based on if the list of words was static or dynamic... If the
RegEx proved to have a performance problem then I would replace the
Algorithm with a more efficient one... (if one could be found that was truly
more efficient in the context of the routine).
Hope this helps

No, actually all I would want to know is if any of the strings exists in the
line. I want it to work pretty much the way the SQL IN verb works. i.e.
where Status in ('ACTIVE','OTHER')
Which brings up an interesting question: Is there any kind of IN verb
anywhere in VB.NET or the .NET framework?
But thanks for all the suggestions; I think I will try to make up a function
or something that I can call to do this.

Herfried: Yep, I can do it this way, and that is pretty much how I have been
doing it. I just thought there had to be some other intrinsic built-in way
of doing it without having to write the code. That would be a good function
to have in the .NET framework.
I wonder if using a RegEx or using your method would be faster?

I think the theoretically fastest implementation would be an adapted version
of the Boyer Moore algorithm or the KMP pattern matching algorithm. By
calling 'InStr' three times (for looking for the occurance of three strings
in the text) there may be comparisons done that don't need to be done with a

Herfried,
I was thinking about just making a sample method as is the indexofArray and
than with strings, cannot be that hard when you everytime move the index of
a string one position and test it than against the string when the position
is less than the lenght of the search word.
Than would the instr be faster than the indexof, however it would be a
little bit strange routine when I would make this, because I would use the
substring instead of the Mid.
Both should be very easy to be done and probably be the fastest routine, and
when you are sure it are bytes and no unicodes even faster to be done with a
bytearray.
However with methods in previouw message I did mean all methods which are
standard in dotnet as regex, indexof, etc.

Tom,
As we all suggested there is no builtin "In" function per se.
I would use the RegEx as its IMHO the "simplest" & "cleanest"
implementation! However! you need to understand RegEx to be comfortable
using it, luckily this regex is easy. Also you may need to get over the
perception that RegEx is slow. Yes it has some inherit overhead the other
methods do not, however that overhead may be warranted for the simplicity of
the routine. Also based on the context the overhead of the RegEx may be
lower, significantly lower, then other routines.
Note: I would only use the RegEx method for checking Strings, if I was
creating an "In" for other types I would pick an algorithm that was more
friendly for that type.
Here's one possibility for an "In" function based on RegEx.
Public Shared Function [In](ByVal input As String, ByVal ParamArray
words() As String) As Boolean
Dim pattern As String = String.Join("|", words)
Return System.Text.RegularExpressions.Regex.IsMatch(input , pattern)
End Function
Then to use it you simple need to:
strTest = "The cat jumped over the sleepy dog."
If [In](strTest, "cat","dog", "sleep") Then
Debug.WriteLine("Found strings")
Else
Debug.WriteLine("Did NOT find strings!")
End If
If the above RegEx version proved to be a performance problem I would then
consider using a For Each loop.
Public Shared Function [In](ByVal input As String, ByVal ParamArray
words() As String) As Boolean
For Each word As String In words
If input.IndexOf(word) <> -1 Then
Return True
End If
Next
Return False
End Function
I would consider creating an object that contained a list of words, which
had a method the checked to see if a string had one of those words.
Public Class ValidValues
Private ReadOnly m_regex As System.Text.RegularExpressions.Regex
Public Sub New(ByVal ParamArray words() As String)
Dim pattern As String = String.Join("|", words)
m_regex = New System.Text.RegularExpressions.Regex(pattern,
System.Text.RegularExpressions.RegexOptions.Compil ed)
End Sub
Public Function IsMatch(ByVal value As String) As Boolean
Return m_regex.IsMatch(value)
End Function
End Class
Dim values As New ValidValues("cat", "dog", "sleep")
If values.IsMatch(strTest) Then
Debug.WriteLine("Found strings")
Else
Debug.WriteLine("Did NOT find strings!")
End If
Return
Dim statusValues As New ValidValues("ACTIVE","OTHER")
If statusValues.IsMatch(Status) Then
...
Notice in both cases that the actual method (algorithm) of matching is
hidden (encapsulated) within either the object or the function itself. Which
allows you to replace the Algorithm with a more efficient one if needed...
Whether I used the Function or Class would depend on how the function or
class was being within my program... Using Refactoring http://www.refactoring.com I can change between the two...
As the others pointed out there are other equally valid ways to implement
the above. There are also methods that have yet to be mentioned, such as
using a HashTable or using a DataSet, plus still others. Which one you
should use REALLY depends on the context of what you are doing!
For example if your status value is in a DataTable, you can use a filter
statement that include an "In" statement, on either DataTable.Select or
DataView.RowFilter. Like wise of the list of valid statues are in a
DataTable, you could use DataTable.Rows.Find assuming that the status was
the primary key to that table, or use filter & either DataTable.Select or
DataView.RowFilter...
Hope this helps
