How to Convert Textboxes to Array/List in VB.NET/C#

Array of Textboxes using VB.NET/C# / Loop through Textboxes in VB.NET

Here is a simple code that loops through all the controls on a Windows form and Appends the Array/List with the values

Sub GetTextBoxValues()

        Dim arTextBoxVal() As String
        Dim arTBCnt As Integer = 0
        Dim ListTB As New List(Of String)

        For Each ctlText In Me.Controls
            If TypeOf ctlText Is TextBox Then
                ReDim Preserve arTextBoxVal(arTBCnt)
                arTextBoxVal(arTBCnt) = DirectCast(ctlText, TextBox).Text
                ListTB.Add(DirectCast(ctlText, TextBox).Text)
                arTBCnt += 1
            End If
        Next

    End Sub

How to Add an Array to List using C# /.NET

Add Range to List using C# / .NET

Let us take our own IPL example. The current IPL has eight teams that are part of the list

            List lstIPLTeams = new List();

            lstIPLTeams.Add("Mumbai Indians");
            lstIPLTeams.Add("Chennai SuperKings");
            lstIPLTeams.Add("Kolkatta KnightRiders");
            lstIPLTeams.Add("Deccan Chargers");
            lstIPLTeams.Add("Rajastan Royals");
            lstIPLTeams.Add("Delhi DareDevils");
            lstIPLTeams.Add("KingsXI Punjab");
            lstIPLTeams.Add("RC Bangalore");

From next year two new teams- Pune and Kochi - will be part of IPL

Hence we are adding those two teams to an Array and adding the array using AddRange method

            string[] NewIPLTeams = { "Pune", "Kochi" };
            lstIPLTeams.AddRange(NewIPLTeams);

            Console.WriteLine("\nList After Add Range");
            Console.WriteLine("=======================");
            foreach (string IPL in lstIPLTeams)
            {
                Console.WriteLine(IPL.ToString());
            }

This will add Pune and Kochi to end of the list
