How to pass data from one form to another in Windows Forms like Session in Web

In Windows Form Application concept of Session is not available. Please refer the below code for verification.

In Form1 i am having two TextBox for UserName and Password and a Button to Login. I am assigning the UserName TextBox value to static variable after successful authentication.

C#

Form1.cs

private void btnLogin_Click(object sender, EventArgs e)
{
    //After successful verification
    Class1.userName = this.txtUserName.Text;
    Form2 f2 = new Form2();
    f2.Show();
    this.Hide();
}

In Form2 load event i am just displaying the UserName in Label.

private void Form2_Load(object sender, EventArgs e)
{
    this.lblUserInfoName.Text = string.Format("Welcome {0}", Class1.userName);
}

This is my static class

public static class Class1
{
    public static string userName;
}

VB.Net

Form1.vb

Private Sub btnLogin_Click(ByVal sender As Object, ByVal e As EventArgs)
    Class1.userName = Me.txtUserName.Text
    Dim f2 As Form2 = New Form2()
    f2.Show()
    Me.Hide()
End Sub

In Form2 load event i am just displaying the UserName in Label.

Private Sub Form2_Load(ByVal sender As Object, ByVal e As EventArgs)
    Me.lblUserInfoName.Text = String.Format("Welcome {0}", Class1.userName)
End Sub

This is my static class

Module Class1
    Public Shared userName As String
End Module
