How do I declare a single Object instance then reuse it in each ComboBox?

Expand Post »

All these New Object()s are identical (and in fact, much longer!) How do I declare a single instance then reuse it in each ComboBox .Items.AddRange()? I am using Visual Studio 2008/Visual Basic.

VB.NET Syntax (Toggle Plain Text)
verticalBarComboBox.Items.AddRange(New Object() {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"})
 backSlashComboBox.Items.AddRange(New Object() {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"})
 colonComboBox.Items.AddRange(New Object() {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"})
 quoteComboBox.Items.AddRange(New Object() {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"})
verticalBarComboBox.Items.AddRange(New Object() {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"})
 backSlashComboBox.Items.AddRange(New Object() {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"})
 colonComboBox.Items.AddRange(New Object() {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"})
 quoteComboBox.Items.AddRange(New Object() {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"})

Thanks!

Re: How do I declare a single Object instance then reuse it in each ComboBox?

As RamyMahrous said use an array. If you deceide to add or remove anything later you only need to do it in one place.

VB.NET Syntax (Toggle Plain Text)
    Dim ary As String() = {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"}
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        verticalBarComboBox.Items.AddRange(ary)
        backSlashComboBox.Items.AddRange(ary)
        colonComboBox.Items.AddRange(ary)
        quoteComboBox.Items.AddRange(ary)
    End Sub
    Dim ary As String() = {" single space", "- hyphen", " -  <single space>hyphen<single space>", "` open single quote", "=", "~", "!"}

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        verticalBarComboBox.Items.AddRange(ary)
        backSlashComboBox.Items.AddRange(ary)
        colonComboBox.Items.AddRange(ary)
        quoteComboBox.Items.AddRange(ary)
    End Sub

Thanks to both!

As this is my first VB project, I needed the code snippet.
