Send your textbox cotrol with parametr of your Delete method:


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

    public void butDelete_Click(object sender, EventArgs e)
    {
        Delete delete = new Delete();
        delete.Delete(txtName);
    }
}


class Delete
{
    public Delete(Control control)
    {
         var txtBox = control as TextBox;
         if (txtBox == null)
            return;
         txtBox.ResetText();
    }
}

Pass text box object as parameter.

class Delete
{
    public Delete(TextBox txtName)
    {
        txtName.ResetText();
    }
}
