Different Ways of Passing Values from One Form to another in VB.NET and C#

Label1.Text = Form1.TextBox1.Text

Public Sub New(ByVal value As String)

        InitializeComponent()

        Label1.Text = value

End Sub 

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

Dim f As New Form2(TextBox1.Text)

      f.Show()

End Sub

‘ This will Call the Instance of the Open form on the zero index.
Dim f As Form1 = Application.OpenForms(0)
Label1.Text = f.TextBox1.Text

        public void SetValue(string value)
        {
            label1.Text=value;
        }

           Form2 f = new Form2();
           f.SetValue(textBox1.Text);
           f.Show();

    public Form2(string value)
    {
       InitializeComponent();
       label1.Text = value;
    }

   private void button2_Click(object sender, EventArgs e)
   {
         Form2 f = new Form2(textBox1.Text);
         f.Show();
   }

Form1 f = (Form1)Application.OpenForms[0];
label1.Text = f.TextBoxValue;
