Array Search and Sort Methods in vb.net

Array Search and Sort Methods in vb.net

You can now have arrays search themselves or sort themselves. Here’s an example showing how to use both the sort and search methods of the Array object. The syntax for these two methods is as follows:

Array.Sort(myArray)

And

arrayIndex = Array.BinarySearch(myArray, “Name”)

To see this feature in action, put a Button and a TextBox control on a form and change the TextBox’s MultiLine property to True. Then enter the following

====================================================================

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim myarray(3) As String

myarray.SetValue("zoo", 0)

myarray.SetValue("brief", 1)

myarray.SetValue("area", 2)

myarray.SetValue("trim", 3)

Dim x As String

Dim show As String

x = Chr(13) & Chr(10)

Dim i As Integer

For i = 0 To 3

show = show & myarray(i) & x

Next

TextBox1.Text = show & x & x & "Array:" & x

Array.Sort(myarray)

show = ""

For i = 0 To 3

show = show & myarray(i) & x

Next

TextBox2.Text = show & x & "SORTED:" & x

Dim anrrayIndex As Integer

anrrayIndex = Array.BinarySearch(myarray, "area")

show = CStr(anrrayIndex)

MsgBox("The word area was found at the " & show & " index within the array")

End Sub
