newbie problem with array

This is VBNET2005

I feel like I'm missing something really obvious here.

I keep getting the error "Value of type 'string' cannot be converted
to '1 dimensional array of string'"

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles Button1.Click

        Dim inputstream As New
System.IO.StreamReader("c:\testfile.txt")

        Dim line As String

        line = inputstream.ReadLine()

        Dim testarray() As String = Split(line)

        TextBox1.Lines = testarray(1)

        inputstream.Close()

    End Sub
End Class

Any help appreciated.

EEjit,

I think that you can do

> Dim testarray() As String = Split(line)
>
> TextBox1.Lines = testarray(1)

Textbox1.text = testarray(1)
or
Textbox1.lines = testararray.length

I hope this helps,

This will result in an error as the Lines property of the TextBox is an
array of strings and not an integer.

I was once searching for that lines property because it is in a mater of way
the equivalent to the multiline option. I could not find it anymore. This
showes that it was not deleted, however completely removed from my memory.

Thanks for pointing me on this.

\\\
Me.TextBox1.Lines = testarray
///

- or -

\\\
Me.TextBox1.Text = testarray(1)
///

depending on what you want to archieve.
