c# - StatusStrip の水平分割線

Question

アプリケーションで、Windows.Formsの水平分割線の色を変更したいStatusStrip、またはこの線を非表示にしたい。何か案は？

これは私が言及しているものです：

ファイル: Program.cs

using System;
using System.Data;
using System.Drawing;
using System.Data.Linq;
using System.Windows.Forms;

namespace test {
    class Program {

        [STAThread]

        static void Main() {
            Application.Run(new FormMain());
        }
    }
}

ファイル: FormMain.cs

using System;
using System.Data;
using System.Drawing;
using System.Data.Linq;
using System.Windows.Forms;

namespace test {
    class Vars {
        public class Colors {
            public static Color BackRed = Color.FromArgb(040, 000, 000);
            public static Color ForeRed = Color.FromArgb(240, 120, 120);
            public static Color BackGrn = Color.FromArgb(000, 040, 000);
            public static Color ForeGrn = Color.FromArgb(120, 240, 120);
            public static Color BackBlu = Color.FromArgb(000, 000, 040);
            public static Color ForeBlu = Color.FromArgb(120, 120, 240);
        }
    }

    class FormMain : Form {
        MenuStrip menuStrip = new MenuStrip();
        StatusStrip statusStrip = new StatusStrip();

        public FormMain() {
            this.FormMain_Setup();
        }

        private void FormMain_Setup() {
            this.Top = 20;
            this.Left = 20;
            this.Width = 1200;
            this.Height = 675;
            this.BackColor = Vars.Colors.BackBlu;
            this.ForeColor = Vars.Colors.ForeBlu;
            this.MaximizeBox = false;
            this.StartPosition = FormStartPosition.Manual;
            this.FormBorderStyle = FormBorderStyle.Fixed3D;
            this.KeyDown += FormMain_KeyDown;
            this.FormMain_MenuStrip_Setup();
            this.FormMain_StatusStrip_Setup();
        }

        private void FormMain_StatusStrip_Setup() {
            this.statusStrip.Height = 30;
            this.statusStrip.AutoSize = false;
            this.statusStrip.BackColor = Vars.Colors.BackRed;
            this.statusStrip.ForeColor = Vars.Colors.ForeRed;
            this.statusStrip.SizingGrip = false;
            this.Controls.Add(statusStrip);
        }

        private void FormMain_MenuStrip_Setup() {
            this.menuStrip.Height = 30;
            this.menuStrip.AutoSize = false;
            this.menuStrip.BackColor = Vars.Colors.ForeGrn;
            this.menuStrip.ForeColor = Vars.Colors.BackGrn;
            this.Controls.Add(menuStrip);
        }

        private void FormMain_KeyDown(object sender, KeyEventArgs e) {
            this.FormMain_Exit();
        }

        private void FormMain_Exit() {
            this.Close();
        }
    }
}
