利用panel進行並列多行的架構與利用button實現圖片和文字共存

1.利用panel形式，可以進行多行的展示

        private void PB_Click(object sender, EventArgs e)
        {
            if (sender is Button)
            {
                Button temp = (Button)sender;
                if (temp.TabIndex == FormIndex)
                {
                    return;
                }
                else
                {
                    FormIndex = temp.TabIndex;
                }
            }
           else
            {
               FormIndex=0;
            
            }

                for (int i = 0; i < this.MdiChildren.Length; i++)
                {
                    ((Form)(this.MdiChildren[i])).Close();
                }
                Form Frm = null;

                //1.登錄
                //2.單元格管理
                //3.IO管理
                //4.工藝
                //5.產品
                //6.生產
                //7.分析
                //8.警報
                //9.設置

                if (FormIndex==0)
                {
                    Frm = new Frm_Login();
                }
                if (FormIndex == 1)
                {
                    Frm = new Frm_Cell();
                }
                if (FormIndex == 2)
                {
                    Frm = new Frm_IO();
                }
                if (FormIndex ==3)
                {
                    Frm = new Frm_Preset();
                }
                if (FormIndex == 4)
                {
                    Frm = new Frm_Recipe();
                }
                if (FormIndex ==5)
                {
                    Frm = new Frm_Product();
                }

                if (FormIndex == 6)
                {
                    Frm = new Frm_Analysis();
                }
                if (FormIndex ==7)
                {
                    Frm = new Frm_Alarm();
                }
                if (FormIndex == 8)
                {
                    Frm = new Frm_Setting();
                }
              
                 Frm.MdiParent = this;
                 Frm.Size = this.PanForm.Size;
                 Frm.WindowState = FormWindowState.Maximized;
                 this.PanForm.Controls.Add(Frm);
                 Frm.Dock = DockStyle.Fill;
                 Frm.Show();
            
        }

利用button來實現文字與圖片共存效果

            this.BT_Product.Anchor = System.Windows.Forms.AnchorStyles.None;
            this.BT_Product.BackColor = System.Drawing.Color.Transparent;
            this.BT_Product.FlatAppearance.BorderColor = System.Drawing.Color.White;
            this.BT_Product.FlatAppearance.BorderSize = 0;
            this.BT_Product.FlatStyle = System.Windows.Forms.FlatStyle.Flat;
            this.BT_Product.Font = new System.Drawing.Font("Arial", 10F, System.Drawing.FontStyle.Bold);
            this.BT_Product.Image = global::PanMAN.Properties.Resources.Staubli_painting1;
            this.BT_Product.ImageAlign = System.Drawing.ContentAlignment.TopCenter;
            this.BT_Product.Location = new System.Drawing.Point(52, 358);
            this.BT_Product.Name = "BT_Product";
            this.BT_Product.Size = new System.Drawing.Size(88, 61);
            this.BT_Product.TabIndex = 5;
            this.BT_Product.Text = "生產管理";
            this.BT_Product.TextAlign = System.Drawing.ContentAlignment.BottomCenter;
            this.BT_Product.UseVisualStyleBackColor = true;
            this.BT_Product.Click += new System.EventHandler(this.PB_Click);
