Hi abualmazen,

Refer below sample.

Code

private void Form1_Load(object sender, EventArgs e)
{
    Label lbl = new Label();
    lbl.Name = "lblMessage";
    lbl.Text = "ASPSNippets.com";
    Button btn = new Button();
    btn.Name = "btnShow";
    btn.Text = "Get"; 
    btn.Height = 25;
    btn.Width = 70;
    flowLayoutPanel1.Controls.Add(lbl);
    flowLayoutPanel1.Controls.Add(btn);
    btn.Click += new EventHandler(GetValue);
}

private void GetValue(object sender, EventArgs e)
{
    foreach (Control c in flowLayoutPanel1.Controls)
    {
        if(c.GetType()==typeof(Label))
        {
            MessageBox.Show(c.Text);
        }
    }
}

VB.Net

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)Handle Me.Load
        Dim lbl As Label = New Label()
        lbl.Name = "lblMessage"
        lbl.Text = "ASPSNippets.com"
        Dim btn As Button = New Button()
        btn.Name = "btnShow"
        btn.Text = "Get"
        btn.Height = 25
        btn.Width = 70
        flowLayoutPanel1.Controls.Add(lbl)
        flowLayoutPanel1.Controls.Add(btn)
        AddHandler btn.Click, AddressOf Me.GetValue
    End Sub
    Private Sub GetValue(ByVal sender As Object, ByVal e As EventArgs)
        For Each c As Control In flowLayoutPanel1.Controls
            If c.GetType() = GetType(Label) Then
                MessageBox.Show(c.Text)
            End If
        Next
    End Sub
