使用System.Windows.Form不为灰色

Question

I've created a windows form called Grades and when I click the Submit button, it displays the "System.Windows.Form" onto the label and then the text I've entered onto the textbox. For example, it displays "System.Windows.Form Tom". Now I've been researching online and people say that I should add it as a reference. I already did that and it seems as though that the using statement isn't greyed in like the other using statements. Please Help!

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Grades
{
     public partial class frmGrades : Form
     {
        public frmGrades()
        {
            InitializeComponent();
        }

        private void btnSubmit_Click(object sender, EventArgs e)
        {
           lblDisplayStudentName.Text = Convert.ToString(txtBoxStudentName);
           lblDisplayMessage.Text = Convert.ToString(txtBoxStudentGrade);
        }
    }
}

Answer 1

You need to get the text property of the textbox :

lblDisplayStudentName.Text = txtBoxStudentName.Text;
lblDisplayMessage.Text = txtBoxStudentGrade.Text;
