Using a delegate to pass a value

public partial class Form2:form
{
Public Form2 ()
{
InitializeComponent ();
}
Public Form2 (String Str,delegate de): this ()//Call the current empty constructor
{
Label1. Text = str; Assign value
this.de = de;//Assignment
}
private void Form2_load (object sender, EventArgs e)
{

}
Private Delegate de;//define delegate Type field
private void Button1_Click (object sender, EventArgs e)
{
String strmsg = TextBox1.Text;
if (de! = null)
{
De (strmsg); Delegate type
}
This. Close ();
}
}

 public Main1 ()
        {
             InitializeComponent ();
       }

private void Button1_Click (object sender, EventArgs e)
{
string content = TextBox1.Text;
Form2 frm2 = new Form2 (CONTENT,MSGSTR); Initialize constructors and assign values, with arguments requiring a delegate type (note: delegate type)
Frm2. Show ();
}
private void MsgStr (String str)
{
TextBox2.Text = str;
}
}
