How to pass parameter in windows form from one form to another?

This is how we can pass parameter from one form to another:

Here is form1:

Parent Form (frmParent)

//Write the code on click event

  frmParent frmObj = new frmParent(strUserID, strRole);

  frmObj.ShowDialog();

Here is form2:

Child Form (frmChild)

public partial class frmChild: Form

    {

      private string strUserID = string.Empty;

private string strRole = string.Empty;

        public frmChild(string strUserID, string strRole)

        {

            this. strUserID = strUserID;

            this. strRole = strRole;

            InitializeComponent();

          

            TextBox1.Text = strUserID;

        }

}
