Copy some part of an array

[sinojen]

I have a problem; I have an array, I want to copy the first x number of variables from the array to a new array (for example variable 0 to 4). Duplicated variables should not be included.
Let's say the array is: 1 8 2 8 7 33 8 27. And I want to copy 5 variables, then the new array should include 1 8 2 7 3

Quick example should help you out. I threw two textboxes and a command button on a form. The code behind the button was:

        Dim aStart() As String = Split(Me.TextBox1.Text, ",")
        Dim AResult(4) As String

        For i As Int32 = 0 To 4
            Dim ArrayPlace As Int32 = 0
            For j As Int32 = 0 To aStart.Count - 1
                If Not AResult.Contains(aStart(j)) Then
                    AResult(i) = aStart(j)
                    Exit For
                End If
            Next
        Next

        Me.TextBox2.Text = Join(AResult, ",")

Should help you get started.

thank you, but I it don't work. I use ASP.NET here, and I am a beginner.
the number x is stored in a variable.

ASP.Net can be driven by either VB or C#. So do you mean you are using C#??

Also, what I gave you was just a sample....not to be your exact code.

You can easily modify this to include some variables, such as

Dim AResult(intPlacesToGrab) As String

For i As Int32 = 0 To intPlacesToGrab

And you only need to passthe code the necessary intPlacesToGrab variable. That will make it grab the number of values you want.

Please give us a bit more on your situation, what doesn't work, and what - if any - errors you are getting to better help you.

Microsoft .NET Framework version:2.0.50727.312
ASP.NET version:2.0.50727.833

I do write in Visual BASIC .net

I got an error:
Error BC30456

"Contains" is not a member of "System.Array

I am not an ASP.NET person at all (my company is sending me to a class next month on it). The above code was quickly thrown into a Windows Application and worked as expected in several tests.

You might try replacing:

If Not AResult.Contains(aStart(j)) Then

with

If AResult.IndexOf(aStart(j)) = -1 Then

That basically performs the same check and may be available in the Web namespaces. If not, I would take this sample I have provided and move over to the ASP.NET forum (

http://www.tek-tips.com/threadminder.cfm?pid=855),

letting them know this came from a Windows app, and ask them to help you modify it for ASP.

Good luck.

BC30452: Operator '-' is not defined

I think I ask in the ASP.NET forum. I did not know there was one here, until now. Thank you
