unable to return the textbox value to condition checking Input string was not in a correct format

Question

I am trying to display the message box as per the textbox i am getting the error, anybody please help on this :

namespace WindowsApplication7
{
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        this.label1.Text = textBox1.Text;
    }

    private void label1_TextChanged(object sender, EventArgs e)
    {
        if (int.Parse(label1.Text) >= 120)
        {
            MessageBox.Show("Dot Net Perls is awesome.",
    "Important Message");

        }
    }
 }
}

That means that the value of `label1` is not convertible to an integer, which the error message states. — VDWWD, Jul 21 '18 at 12:30

Try this :

        int value= 0;
        if (int.TryParse(textBox1.Text, out value))
        {
            if (value>= 120)
                MessageBox.Show("Dot Net Perls is awesome.",
                         "Important Message");
        }
