Set value to another form

Question

I have to form Form1 and Form2

Form1 source

namespace WindowsFormsApplication1
{
    public partial class Form1 :          


        

Answer 1

Use Constructor method , here is example

In form2

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

In form1 click event

private void label1_Click(object sender, System.EventArgs e)
{
Form2 frm=new Form2(textBox1.Text);
frm.Show();
}
